Complementarity of Private and Correctable Subsystems in Quantum Cryptography and Error Correction
Dennis Kretschmann, David W. Kribs, Robert W. Spekkens
We make an explicit connection between fundamental notions in quantum cryptography and quantum error correction. Error-correcting subsystems (and subspaces) for quantum channels ar…
The resource theory of quantum reference frames: manipulations and monotones
Gilad Gour, Robert W. Spekkens
Every restriction on quantum operations defines a resource theory, determining how quantum states that cannot be prepared under the restriction may be manipulated and used to circu…
Negativity and contextuality are equivalent notions of nonclassicality
Robert W. Spekkens
Two notions of nonclassicality that have been investigated intensively are: (i) negativity, that is, the need to posit negative values when representing quantum states by quasiprob…
Einstein, incompleteness, and the epistemic view of quantum states
Nicholas Harrigan, Robert W. Spekkens
Does the quantum state represent reality or our knowledge of reality? In making this distinction precise, we are led to a novel classification of hidden variable models of quantum…
