Generic local distinguishability and completely entangled subspaces
Jonathan Walgate, A. J. Scott
A subspace of a multipartite Hilbert space is completely entangled if it contains no product states. Such subspaces can be large with a known maximum size, S, approaching the full…
Local Distinguishability of Any Three Quantum States
Somshubhro Bandyopadhyay, Jonathan Walgate
We prove that any three linearly independent pure quantum states can always be locally distinguished with nonzero probability regardless of their dimension, entanglement, or multip…
On the logical structure of Bell theorems without inequalities
Anne Broadbent, Hilary A. Carteret, Andre Allan Methot +1
Bell theorems show how to experimentally falsify local realism. Conclusive falsification is highly desirable as it would provide support for the most profoundly counterintuitive fe…
Optimal fingerprinting strategies with one-sided error
A. J. Scott, Jonathan Walgate, Barry C. Sanders
Fingerprinting enables two parties to infer whether the messages they hold are the same or different when the cost of communication is high: each message is associated with a small…
Classical and quantum fingerprinting with shared randomness and one-sided error
Rolf T. Horn, A. J. Scott, Jonathan Walgate +3
Within the simultaneous message passing model of communication complexity, under a public-coin assumption, we derive the minimum achievable worst-case error probability of a classi…
Nonlocality, Asymmetry, and Distinguishing Bipartite States
Jonathan Walgate, Lucien Hardy
Entanglement is an useful resource because some global operations cannot be locally implemented using classical communication. We prove a number of results about what is and is not…
