Quantum digital signatures without quantum memory.
TLDR
We present a QDS scheme where no quantum memory is required, which also needs just linear optics. Expand

Quantum digital signatures with quantum-key-distribution components
Digital signatures guarantee the authenticity and transferability of messages and are widely used in modern communication. The security of currently used classical digital signature schemes, however,Expand

Rigidity of quantum steering and one-sided device-independent verifiable quantum computation
The relationship between correlations and entanglement has played a major role in understanding quantum theory since the work of Einstein, Podolsky and Rosen (1935). Tsirelson (1980) proved that BellExpand

Optimised resource construction for verifiable quantum computation
TLDR
We present here a new construction that simplifies the required resources for any such verifiable protocol. Expand

Spacelike distance from discrete causal order
Any discrete approach to quantum gravity must provide some prescription as to how to deduce continuum properties from the discrete substructure. In the causal set approach it is straightforward toExpand

A histories perspective on characterizing quantum non-locality
We introduce a framework for studying non-locality and contextuality inspired by the path integral formulation of quantum theory. We prove that the existence of a strongly positive joint quantumExpand

Quantum Covers in Quantum Measure Theory
Sorkin’s recent proposal for a realist interpretation of quantum theory, the anhomomorphic logic or coevent approach, is based on the idea of a “quantum measure” on the space of histories. This is aExpand
