Robert W. Spekkens is a Canadian theoretical quantum physicist working in the fields of quantum foundations and quantum information. [1] [2] [3]

Contents

He is known for his work on epistemic view of quantum states (in particular the Spekkens toy model), [4] [5] [6] quantum contextuality, [7] [8] [9] quantum resource theories [10] [11] and quantum causality. [12] [13]

He co-edited the book Quantum Theory: Informational Foundations and Foils. [14]

Career

Spekkens is a faculty member and the leader of the quantum causal inference initiative at Perimeter Institute for Theoretical Physics. [15] [16] He regularly teaches the course on quantum foundations in the Perimeter Scholars International master's program. [17] [18]

He is an adjunct faculty in the Department of Physics of the University of Waterloo [19] and an adjunct research fellow in the Centre for Quantum Dynamics of Griffith University in Brisbane, Australia. [15]
