Complete parameterization and parameter-space topology of discrete Wigner representations on phase space
Lucky K. Antonopoulos, Nicolas C. Menicucci
Toroidal discrete Wigner functions (DWFs) for finite-dimensional systems are non-unique. We completely parameterize and topologically classify the labeled single-qudit ${d\times d}…
Gaussian dynamics in the double Siegel disk
Giacomo Pantaleoni, Nicolas C. Menicucci
We show that deterministic multimode Gaussian channels admit a symmetric-space description. Passing from the n-mode Siegel disk to a doubled version of that space lets general Gaus…
Logical channel for heralded and pure loss with the Gottesman-Kitaev-Preskill code
Tom B. Harris, Takaya Matsuura, Ben Q. Baragiola +1
Photon loss is the dominant source of noise in optical quantum systems. The Gottesman-Kitaev-Preskill (GKP) bosonic code provides significant protection; however, even low levels o…
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…
Quantum-Enhanced Multi-Parameter Sensing in a Single Mode
Christophe H. Valahu, Matthew P. Stafford, Zixin Huang +7
Precision metrology underpins scientific and technological advancements. Quantum metrology offers a pathway to surpass classical sensing limits by leveraging quantum states and mea…
