Miles John Padgett (born 1 June 1963 [1] [2] ) is a Royal Society Research Professor of Optics in the School of Physics and Astronomy at the University of Glasgow. [7] He has held the Kelvin Chair of Natural Philosophy since 2011 [8] [5] [9] [10] [11] and served as Vice Principal for research at Glasgow from 2014 to 2020. [12] [13] [14] [15] [16]
Padgett was educated at the University of Manchester, the University of York, the University of St Andrews, and Trinity College, Cambridge, [2] where he was awarded a PhD in 1988.
Working with Les Allen, Padgett conducted pioneering work on optical angular momentum, [3] for which they were awarded 2009 the Young Medal. [4] The research group he leads is best known for its work on the fundamental properties of light's angular momentum, including optical tweezers and optical spanners, [17] the use of orbital angular momentum states to extend the alphabet of optical communication (with both classical and quantum light), and demonstrations of an angular form of the EPR paradox. [18] Padgett's research has been published in leading peer-reviewed scientific journals including Science , [19] [20] [21] [22] [23] Nature , [24] [25] Physical Review Letters , [3] and Optics Express [10] and Progress in Optics . [11] Padgett's research has been funded by the Engineering and Physical Sciences Research Council (EPSRC). [26]
Padgett was elected a Fellow of the Royal Society of Edinburgh (FRSE) in 2001, [27] in 2011 he was elected a Fellow of the Optical Society and in 2012 a Fellow of the Society of Photographic Instrumentation Engineers (SPIE). In 2014 he was elected a Fellow of the Royal Society (FRS) – the UK's National Academy of Science. [27] His nomination for the Royal Society reads:
Padgett is internationally recognised for his leadership in the field of optics and in particular of optical momentum. His best known contributions include an optical spanner for spinning micron-sized objects, use of orbital angular momentum to increase the data capacity of communication systems and an angular form of the Einstein-Podolsky-Rosen (EPR) quantum paradox. [7]
In 2009, with Les Allen, he won the Institute of Physics (IOP) Young Medal and in 2014 Padgett was awarded the Royal Society of Edinburgh's Lord Kelvin Medal. In 2015 he won the Science of Light Prize [28] from the European Physical Society [8] [29] , in 2017 the Max Born Award [30] of The Optical Society (OSA) and in 2019 the Rumford Medal [31] of the Royal Society. Padgett is a Fellow of the Institute of Physics (FInstP). [1]
Padgett was appointed Officer of the Order of the British Empire (OBE) in the 2020 Birthday Honours for services to scientific research and outreach. [32]
As of 2021, Padgett resides in Glasgow with his wife Heather Reid [33] [1] [34] [35] and their daughter, Jenna.
Optical tweezers are scientific instruments that use a highly focused laser beam to hold and move microscopic and sub-microscopic objects like atoms, nanoparticles and droplets, in a manner similar to tweezers. If the object is held in air or vacuum without additional support, it can be called optical levitation.
An optical vortex is a zero of an optical field; a point of zero intensity. The term is also used to describe a beam of light that has such a zero in it. The study of these phenomena is known as singular optics.

Demetri Psaltis is a Greek-American electrical engineer who was the Dean of the School of Engineering at École Polytechnique Fédérale de Lausanne from 2007 to 2017. Since 2024 he is a professor emeritus at EPFL. He is one of the founders of the term and the field of optofluidics. He is also well known for his past work in holography, especially with regards to optical computing, holographic data storage, and neural networks. He is an author of over 1100 publications, contributed more than 20 book chapters, invented more than 50 patents, and currently has a h-index of 105.
The angular momentum of light is a vector quantity that expresses the amount of dynamical rotation present in the electromagnetic field of the light. While traveling approximately in a straight line, a beam of light can also be rotating around its own axis. This rotation, while not visible to the naked eye, can be revealed by the interaction of the light beam with matter.
The orbital angular momentum of light (OAM) is the component of angular momentum of a light beam that is dependent on the field spatial distribution, and not on the polarization. OAM can be split into two types. The internal OAM is an origin-independent angular momentum of a light beam that can be associated with a helical or twisted wavefront. The external OAM is the origin-dependent angular momentum that can be obtained as cross product of the light beam position and its total linear momentum.
Orbital angular momentum multiplexing is a physical layer method for multiplexing signals carried on electromagnetic waves using the orbital angular momentum (OAM) of the electromagnetic waves to distinguish between the different orthogonal signals.

Roberto Morandotti is a physicist and full Professor, working in the Energy Materials Telecommunications Department of the Institut National de la Recherche Scientifique. The work of his team includes the areas of integrated and quantum photonics, nonlinear and singular optics, as well as terahertz photonics.
Electrons in free space can carry quantized orbital angular momentum (OAM) projected along the direction of propagation. This orbital angular momentum corresponds to helical wavefronts, or, equivalently, a phase proportional to the azimuthal angle. Electron beams with quantized orbital angular momentum are also called electron vortex beams.

In quantum computing, quantum memory is the quantum-mechanical version of ordinary computer memory. Whereas ordinary memory stores information as binary states, quantum memory stores a quantum state for later retrieval. These states hold useful computational information known as qubits. Unlike the classical memory of everyday computers, the states stored in quantum memory can be in a quantum superposition, giving much more practical flexibility in quantum algorithms than classical information storage.
