Contextuality without access to a tomographically complete set
Matthew F. Pusey, Lídia del Rio, Bettina Meyer
The non-classicality of single quantum systems can be formalised using the notion of contextuality. But can contextuality be convincingly demonstrated in an experiment, without ref…
Anomalous weak values and contextuality: robustness, tightness, and imaginary parts
Ravi Kunjwal, Matteo Lostaglio, Matthew F. Pusey
Weak values are quantities accessed through quantum experiments involving weak measurements and post-selection. It has been shown that 'anomalous' weak values (those lying beyond t…
Verifying the quantumness of a channel with an untrusted device
Matthew F. Pusey
Suppose one wants to certify that a quantum channel is not entanglement-breaking. I consider all four combinations of trusted and untrusted devices at the input and output of the c…
Quantum lost property: a possible operational meaning for the Hilbert-Schmidt product
Matthew F. Pusey, Terry Rudolph
Minimum error state discrimination between two mixed states ρand σcan be aided by the receipt of "classical side information" specifying which states from some convex decomposition…
