Gaussian states in quantum field theory: Exact representations of relative phase in superpositions of Gaussian states
Nicholas Funai
Gaussian quantum mechanics is a powerful tool regularly used in quantum optics to model linear and quadratic Hamiltonians efficiently. Recent interest in qubit-CV hybrid models has…
Emergent metric from wavelet-transformed quantum field theory
Šimon Vedl, Daniel J. George, Fil Simovic +5
We introduce a method of reverse holography by which a bulk metric is shown to arise from locally computable multiscale correlations of a boundary quantum field theory (QFT). The m…
Grand Unification of All Discrete Wigner Functions on Phase Space
Lucky K. Antonopoulos, Dominic G. Lewis, Jack Davis +2
Wigner functions help visualise quantum states and dynamics while supporting quantitative analysis in quantum information. In the discrete setting, many inequivalent constructions…
Faster-than-light signalling in the rotating-wave approximation
Nicholas Funai, Eduardo Martin-Martinez
We present new results on the causality violations introduced by the rotating wave approximation commonly used in quantum optics and high-energy physics. We find that the causality…
vs : Gauge invariance in quantum optics
Nicholas Funai, Jorma Louko, Eduardo Martin-Martinez
We compare the predictions of the fundamentally motivated minimal coupling () and the ubiquitous dipole coupling ($\hat{\boldsymbol{x…
