Timeline of quantum computing

This is a timeline of quantum computing .

1960s

• 1960
  • Stephen Wiesner invents conjugate coding. ^[1]

1970s

• 1970
  • James Park articulates the no-cloning theorem ^[2]

• 1973
  • Alexander Holevo publishes a paper showing that n qubits can carry more than n classical bits of information, but at most n classical bits are accessible (a result known as "Holevo's theorem" or "Holevo's bound").
  • Charles H. Bennett shows that computation can be done reversibly. ^[3]
• 1975
  • R. P. Poplavskii publishes "Thermodynamical models of information processing" (in Russian) ^[4] which showed the computational infeasibility of simulating quantum systems on classical computers, due to the superposition principle.
• 1976
  • Polish mathematical physicist Roman Stanisław Ingarden publishes a seminal paper entitled "Quantum Information Theory" in Reports on Mathematical Physics, vol. 10, 43–72, 1976. (The paper was submitted in 1975.) It is one of the first attempts at creating a quantum information theory, showing that Shannon information theory cannot directly be generalized to the quantum case, but rather that it is possible to construct a quantum information theory, which is a generalization of Shannon's theory, within the formalism of a generalized quantum mechanics of open systems and a generalized concept of observables (the so-called semi-observables).

1980s

• 1980
  • Paul Benioff describes the first quantum mechanical model of a computer. In this work, Benioff showed that a computer could operate under the laws of quantum mechanics by describing a Schrödinger equation description of Turing machines, laying a foundation for further work in quantum computing. The paper ^[5] was submitted in June 1979 and published in April 1980.
  • Yuri Manin briefly motivates the idea of quantum computing ^[6]
  • Tommaso Toffoli introduces the reversible Toffoli gate ^[7] , which, together with the NOT and XOR gates provides a universal set for reversible classical computation.
• 1980
  • At the First Conference on the Physics of Computation, held at MIT in May, Paul Benioff and Richard Feynman give talks on quantum computing. Benioff's built on his earlier 1980 work showing that a computer can operate under the laws of quantum mechanics. The talk was titled “Quantum mechanical Hamiltonian models of discrete processes that erase their own histories: application to Turing machines”. ^[8] In Feynman's talk, he observed that it appeared to be impossible to efficiently simulate an evolution of a quantum system on a classical computer, and he proposed a basic model for a quantum computer. ^[9]
• 1982
  • Paul Benioff further develops his original model of a quantum mechanical Turing machine. ^[10]
  • William Wootters and Wojciech Zurek, ^[11] and independently Dennis Dieks ^[12] rediscover the no-cloning theorem.
• 1984
  • Charles Bennett and Gilles Brassard employ Wiesner's conjugate coding for distribution of cryptographic keys. ^[13]
• 1985
  • David Deutsch, at the University of Oxford, describes the first universal quantum computer. Just as a Universal Turing machine can simulate any other Turing machine efficiently (Church-Turing thesis), so the universal quantum computer is able to simulate any other quantum computer with at most a polynomial slowdown.
• 1988
  • Yoshihisa Yamamoto (scientist) and K. Igeta propose the first physical realization of a quantum computer, including Feynman's CNOT gate. ^[14] Their approach uses atoms and photons and is the progenitor of modern quantum computing and networking protocols using photons to transmit qubits and atoms to perform two-qubit operations.
  • Gerard J. Milburn proposes a quantum-optical realization of a Fredkin gate. ^[15]
• 1989
  • Bikas K. Chakrabarti & collaborators from Saha Institute of Nuclear Physics, Kolkata, propose the idea that quantum fluctuations could help explore rugged energy landscapes by escaping from local minima of glassy systems having tall but thin barriers by tunneling (instead of climbing over using thermal excitations), suggesting the effectiveness of quantum annealing over classical simulated annealing. ^{[16] [17]}

1990s

• 1991
  • Artur Ekert at the University of Oxford, expands on the original proposal by David Deutsch ^[18] , for entanglement-based secure communication. ^[19]
• 1992
  • David Deutsch and Richard Jozsa propose a computational problem that can be solved efficiently with the determinist Deutsch–Jozsa algorithm on a quantum computer, but for which no deterministic classical algorithm is possible. This was perhaps the earliest result in the computational complexity of quantum computers, proving that they were capable of performing some well-defined computational task more efficiently than any classical computer.
• 1993
  • Dan Simon, at Université de Montréal, invents an oracle problem for which a quantum computer would be exponentially faster than a conventional computer. This algorithm introduces the main ideas which were then developed in Peter Shor's factorization algorithm.
• 1994
  • Peter Shor, at AT&T's Bell Labs in New Jersey, discovers an important algorithm. It allows a quantum computer to factor large integers quickly. It solves both the factoring problem and the discrete log problem. Shor's algorithm can theoretically break many of the cryptosystems in use today. Its invention sparked a tremendous interest in quantum computers.
  • First United States Government workshop on quantum computing is organized by NIST in Gaithersburg, Maryland, in autumn.
  • Isaac Chuang and Yoshihisa Yamamoto (scientist) propose a quantum-optical realization of a quantum computer to implement Deutsch's algorithm. ^[20] Their work introduces dual-rail encoding for photonic qubits.
  • In December, Ignacio Cirac, at University of Castilla-La Mancha at Ciudad Real, and Peter Zoller at the University of Innsbruck propose an experimental realization of the controlled-NOT gate with cold trapped ions.
• 1995
  • The first United States Department of Defense workshop on quantum computing and quantum cryptography is organized by United States Army physicists Charles M. Bowden, Jonathan P. Dowling, and Henry O. Everitt; it takes place in February at the University of Arizona in Tucson.
  • Peter Shor proposes the first schemes for quantum error correction. ^[21]
  • Christopher Monroe and David Wineland at NIST (Boulder, Colorado) experimentally realize the first quantum logic gate – the controlled-NOT gate – with trapped ions, following the Cirac-Zoller proposal. ^[22]
• 1996
  • Lov Grover, at Bell Labs, invents the quantum database search algorithm. The quadratic speedup is not as dramatic as the speedup for factoring, discrete logs, or physics simulations. However, the algorithm can be applied to a much wider variety of problems. Any problem that has to be solved by random, brute-force search, can take advantage of this quadratic speedup (in the number of search queries).
  • The United States Government, particularly in a joint partnership of the Army Research Office (now part of the Army Research Laboratory) and the National Security Agency, issues the first public call for research proposals in quantum information processing.
  • Andrew Steane designs Steane codes for error correction. ^[23]
  • David P. DiVincenzo, from IBM, proposes a list of minimal requirements for creating a quantum computer. ^[24]
• 1997
  • David Cory, Amr Fahmy and Timothy Havel, and at the same time Neil Gershenfeld and Isaac L. Chuang at MIT publish the first papers realizing gates for quantum computers based on bulk nuclear spin resonance, or thermal ensembles. The technology is based on a nuclear magnetic resonance (NMR) machine, which is similar to the medical magnetic resonance imaging machine.
  • Alexei Kitaev describes the principles of topological quantum computation as a method for combating decoherence. ^[25]
  • Daniel Loss and David P. DiVincenzo propose the Loss-DiVincenzo quantum computer, using as qubits the intrinsic spin-1/2 degree of freedom of individual electrons confined to quantum dots. ^[26]
• 1998
  • First experimental demonstration of a quantum algorithm. A working 2-qubit NMR quantum computer is used to solve Deutsch's problem by Jonathan A. Jones and Michele Mosca at Oxford University and shortly after by Isaac L. Chuang at IBM's Almaden Research Center and Mark Kubinec and the University of California, Berkeley together with coworkers at Stanford University and MIT. ^[27]
  • First working 3-qubit NMR computer.
  • Bruce Kane proposes a silicon based nuclear spin quantum computer, using nuclear spins of individual phosphorus atoms in silicon as the qubits and donor electrons to mediate the coupling between qubits. ^[28]
  • First execution of Grover's algorithm on an NMR computer.
  • Hidetoshi Nishimori & colleagues from Tokyo Institute of Technology showed that quantum annealing algorithm can perform better than classical simulated annealing.
  • Daniel Gottesman and Emanuel Knill independently prove that a certain subclass of quantum computations can be efficiently emulated with classical resources (Gottesman–Knill theorem). ^[29]
• 1999
  • Samuel L. Braunstein and collaborators show that none of the bulk NMR experiments performed to date contained any entanglement, the quantum states being too strongly mixed. This is seen as evidence that NMR computers would likely not yield a benefit over classical computers. It remains an open question, however, whether entanglement is necessary for quantum computational speedup. ^[30]
  • Gabriel Aeppli, Thomas Felix Rosenbaum and colleagues demonstrate experimentally the basic concepts of quantum annealing in a condensed matter system.
  • Yasunobu Nakamura and Jaw-Shen Tsai demonstrate that a superconducting circuit can be used as a qubit. ^[31] This leads to a global effort to develop quantum computers using superconducting circuits, culminating in Google's demonstration of quantum supremacy using this technology in 2019.

2000s

• 2000
  • Arun K. Pati and Samuel L. Braunstein proved the quantum no-deleting theorem. This is dual to the no-cloning theorem which shows that one cannot delete a copy of an unknown qubit. Together with the stronger no-cloning theorem, the no-deleting theorem has important implication, i.e., quantum information can neither be created nor be destroyed.

They show that they can generate a single photon in a controlled way without the need for randomly formed quantum dots or structural defects in a diamonds. ^{[250] [251]}

• 25 February – Scientists visualize a quantum measurement: by taking snapshots of ion states at different times of measurement via coupling of a trapped ion qutrit to the photon environment they show that the changes of the degrees of superpositions and therefore of probabilities of states after measurement happens gradually under the measurement influence. ^{[252] [253]}

• 2 March – Scientists report to have achieved repeated quantum nondemolition measurements of an electron's spin in a silicon quantum dot: measurements that don't change the electron's spin in the process. ^{[254] [255]}

• 11 March – Quantum engineers report to have managed to control the nucleus of a single atom using only electric fields. This was first suggested to be possible in 1961 and may be used for silicon quantum computers that use single-atom spins without needing oscillating magnetic fields which may be especially useful for nanodevices, for precise sensors of electric and magnetic fields as well as for fundamental inquiries into quantum nature. ^{[256] [257]}

• 19 March – An US Army laboratory announces that its scientists analysed a Rydberg sensor's sensitivity to oscillating electric fields over an enormous range of frequencies—from 0 to 10^12 Hertz (the spectrum to 0.3mm wavelength). The Rydberg sensor may potentially be used detect communications signals as it could reliably detect signals over the entire spectrum and compare favourably with other established electric field sensor technologies, such as electro-optic crystals and dipole antenna-coupled passive electronics. ^{[258] [259]}

• 23 March – Researchers report that they have found a way to correct for signal loss in a prototype quantum node that can catch, store and entangle bits of quantum information. Their concepts could be used for key components of quantum repeaters in quantum networks and extend their longest possible range. ^{[260] [261]}

• 15 April – Researchers demonstrate a proof-of-concept silicon quantum processor unit cell which works at 1.5 Kelvin – many times warmer than common quantum processors that are being developed. It may enable integrating classical control electronics with the qubit array and reduce costs substantially. The cooling requirements necessary for quantum computing have been called one of the toughest roadblocks in the field. ^{[262] [263] [264] [265] [266] [267]}

• 16 April – Scientists prove the existence of the Rashba effect in bulk perovskites. Previously researchers have hypothesized that the materials' extraordinary electronic, magnetic and optical properties – which make it a commonly used material for solar cells and quantum electronics – are related to this effect which to date hasn't been proven to be present in the material. ^{[268] [269]}

• 8 May – Researchers report to have developed a proof-of-concept of a quantum radar using quantum entanglement and microwaves which may potentially be useful for the development of improved radar systems, security scanners and medical imaging systems. ^{[270] [271] [272]}

• 12 May – Researchers report to have developed a method to selectively manipulate a layered manganite's correlated electrons' spin state while leaving its orbital state intact using femtosecond X-ray laser pulses. This may indicate that orbitronics – using variations in the orientations of orbitals – may be used as the basic unit of information in novel IT devices. ^{[273] [274]}

• 19 May – Researchers report to have developed the first integrated silicon on-chip low-noise single-photon source compatible with large-scale quantum photonics. ^{[275] [276] [277] [278]}

• 11 June – Scientists report the generation of rubidium Bose–Einstein condensates (BECs) in the Cold Atom Laboratory aboard the International Space Station under microgravity which could enable improved research of BECs and quantum mechanics, whose physics are scaled to macroscopic scales in BECs, support long-term investigations of few-body physics, support the development of techniques for atom-wave interferometry and atom lasers and has verified the successful operation of the laboratory. ^{[279] [280] [281]}

• 15 June – Scientists report the development of the smallest synthetic molecular motor, consisting of 12 atoms and a rotor of 4 atoms, shown to be capable of being powered by an electric current using an electron scanning microscope and moving even with very low amounts of energy due to quantum tunneling. ^{[282] [283] [284]}

• 17 June – Quantum scientists report the development of a system that entangles two photon quantum communication nodes through a microwave cable that can send information inbetween without the photons ever being sent through, or occupying, the cable. On 12 June it was reported that they also, for the first time, entangled two phonons as well as erase information from their measurement after the measurement has been completed using delayed-choice quantum erasure. ^{[285] [286] [287] [288]}
