Probing many-body correlations using quantum-cascade correlation spectroscopy

Lorenzo Scarpelli, Cyril Elouard, Mattias Johnsson +7

The radiative quantum cascade, i.e. the consecutive emission of photons from a ladder of energy levels, is of fundamental importance in quantum optics. For example, the two-photon…

Asymptotic Equipartition Theorems in von Neumann algebras

Omar Fawzi, Li Gao, Mizanur Rahaman

The Asymptotic Equipartition Property (AEP) in information theory establishes that independent and identically distributed (i.i.d.) states behave in a way that is similar to unifor…

High-performance repetition cat code using fast noisy operations

Francois-Marie Le Régent, Camille Berdou, Zaki Leghtas +2

Bosonic cat qubits stabilized by two-photon driven dissipation benefit from exponential suppression of bit-flip errors and an extensive set of gates preserving this protection. The…

A graph-state based synthesis framework for Clifford isometries

Timothée Goubault de Brugière, Simon Martiel, Christophe Vuillot

We tackle the problem of Clifford isometry compilation, i.e, how to synthesize a Clifford isometry into an executable quantum circuit. We propose a simple framework for synthesis t…

Dynamically enhancing qubit-photon interactions with anti-squeezing

M. Villiers, W. C. Smith, A. Petrescu +7

The interaction strength of an oscillator to a qubit grows with the oscillator's vacuum field fluctuations. The well known degenerate parametric oscillator has revived interest in…

Correlation functions for realistic continuous quantum measurement

Pierre Guilmin, Pierre Rouchon, Antoine Tilloy

We propose a self-contained and accessible derivation of an exact formula for the -point correlation functions of the signal measured when continuously observing a quantum syste…
