Random subspaces for encryption based on a private shared Cartesian frame
Stephen D. Bartlett, Patrick Hayden, Robert W. Spekkens
A private shared Cartesian frame is a novel form of private shared correlation that allows for both private classical and quantum communication. Cryptography using a private shared…
Logical Pre- and Post-Selection paradoxes, measurement-disturbance and contextuality
M. S. Leifer, R. W. Spekkens
Many seemingly paradoxical effects are known in the predictions for outcomes of measurements made on pre- and post-selected quantum systems. A class of such effects, which we call…
Pre- and Post-selection paradoxes and contextuality in quantum mechanics
M. S. Leifer, R. W. Spekkens
Many seemingly paradoxical effects are known in the predictions for outcomes of intermediate measurements made on pre- and post-selected quantum systems. Despite appearances, these…
Entanglement under restricted operations: Analogy to mixed-state entanglement
Stephen D. Bartlett, Andrew C. Doherty, Robert W. Spekkens +1
We show that the classification of bi-partite pure entangled states when local quantum operations are restricted yields a structure that is analogous in many respects to that of mi…
