Unwrapping phase fluctuations in one dimension
William Detmold, Gurtej Kanwar, Michael L. Wagman
Correlation functions in one-dimensional complex scalar field theory provide a toy model for phase fluctuations, sign problems, and signal-to-noise problems in lattice field theory…
Phase Unwrapping and One-Dimensional Sign Problems
William Detmold, Gurtej Kanwar, Michael L. Wagman
Sign problems in path integrals arise when different field configurations contribute with different signs or phases. Phase unwrapping describes a family of signal processing techni…
Algorithms, Bounds, and Strategies for Entangled XOR Games
Adam Bene Watts, Aram W. Harrow, Gurtej Kanwar +1
We study the complexity of computing the commuting-operator value of entangled XOR games with any number of players. We introduce necessary and sufficient criteria for an XOR…
