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]
