Operational protocols cannot certify classicality
Chris Fields, James F. Glazebrook, Antonino Marcianò +1
The existence and practical utility of operational protocols that certify entanglement raises the question of whether operational protocols exist that certify the absence of entang…
Amplituhedra for generic quantum processes via the TQNN representation of UQC
Chris Fields, James F. Glazebrook, Antonino Marcianò +1
We study the relationship between computation and scattering both operationally (hence phenomenologically) and formally. We develop a representation of universal quantum computatio…
Whether a quantum computation employs nonlocal resources is operationally undecidable
Chris Fields, James F. Glazebrook, Antonino Marciano +1
Computational complexity characterizes the usage of spatial and temporal resources by computational processes. In the classical theory of computation, e.g. in the Turing Machine mo…
ER = EPR is an operational theorem
Chris Fields, James F. Glazebrook, Antonino Marciano +1
We show that in the operational setting of a two-agent, local operations, classical communication (LOCC) protocol, Alice and Bob cannot operationally distinguish monogamous entangl…
Communication protocols and QECC from the perspective of TQFT, Part II: QECCs as spacetimes
Chris Fields, James F. Glazebrook, Antonino Marciano
Topological quantum field theories (TQFTs) provide a general, minimal-assumption language for describing quantum-state preparation and measurement. They therefore provide a general…
Separability, Contextuality, and the Quantum Frame Problem
Chris Fields, James F. Glazebrook
We study the relationship between assumptions of state separability and both preparation and measurement contextuality, and the relationship of both of these to the frame problem,…
