Quantum simulation of ultrastrongly coupled bosonic modes using superconducting circuits

S. Fedortchenko, S. Felicetti, D. Marković +5

The ground state of a pair of ultrastrongly coupled bosonic modes is predicted to be a two-mode squeezed vacuum. However, the corresponding quantum correlations are currently unobs…

Efficient quantum communications with multiplexed coherent state fingerprints

Niraj Kumar, Eleni Diamanti, Iordanis Kerenidis

We provide the first example of a communication model and a distributed task, for which there exists a realistic quantum protocol which is asymptotically more efficient than any cl…

Dynamical Observations of Self-Stabilising Stationary Light

Jesse L. Everett, Geoff T. Campbell, Young-Wook Cho +6

Precise control of atom-light interactions is vital to many quantum information protocols. In particular, atomic systems can be used to slow and store light to form a quantum memor…

Surface-modified Wannier-Stark states in a 1D optical lattice

A. Maury, M. Donaire, M. -P. Gorza +2

We study the energy spectrum of atoms trapped in a vertical 1D optical lattice in close proximity to a reflective surface. We propose an effective model to describe the interaction…

Semi-classical Dynamics of Superradiant Rayleigh Scattering in a Bose-Einstein Condensate

J. H. Müller, D. Witthaut, R. le Targat +3

Due to its coherence properties and high optical depth, a Bose-Einstein condensate provides an ideal setting to investigate collective atom-light interactions. Superradiant light s…

Continuous-Variable Instantaneous Quantum Computing is hard to sample

T. Douce, D. Markham, E. Kashefi +5

Instantaneous quantum computing is a sub-universal quantum complexity class, whose circuits have proven to be hard to simulate classically in the Discrete-Variable (DV) realm. We e…

High-efficiency WSi superconducting nanowire single-photon detectors for quantum state engineering in the near infrared

H. Le Jeannic, V. B. Verma, A. Cavaillès +6

We report on high-efficiency superconducting nanowire single-photon detectors based on amorphous WSi and optimized at 1064 nm. At an operating temperature of 1.8 K, we demonstrated…

Measurement of a microwave field amplitude beyond the standard quantum limit

M. Penasa, S. Gerlich, T. Rybarczyk +6

We report a quantum measurement beyond the standard quantum limit (SQL) for the amplitude of a small displacement acting on a cavity field. This measurement uses as resource an ent…

Detecting the spatial quantum uncertainty of bosonic systems

Vanessa Chille, Nicolas Treps, Claude Fabre +3

We present the quantum theory of the measurement of bosonic particles by multipixel detectors. For the sake of clarity, we specialize on beams of photons. We study the measurement…

Simple state preparation for contextuality tests with few observables

S. Camalet

We consider any noncontextuality inequality, and the state preparation scheme which consists in performing any von Neumann measurement on any initial state. For an inequality which…

Electron spin resonance from NV centers in diamonds levitating in an ion trap

Tom Delord, Louis Nicolas, Lucien Schwab +1

We report observations of the Electron Spin Resonance (ESR) of Nitrogen Vacancy (NV) centers in diamonds that are levitating in an ion trap. Using a needle Paul trap operating unde…

Quantum walks and non-Abelian discrete gauge theory

Pablo Arnault, Giuseppe Di Molfetta, Marc Brachet +1

A new family of discrete-time quantum walks (DTQWs) on the line with an exact discrete $U (N)$ gauge invariance is introduced. It is shown that the continuous limit of these DTQWs,…

High resolution transient and permanent spectral hole burning in Ce $^{3 +}$ :Y $_{2}$ SiO $_{5}$ at liquid helium temperatures

Jenny Karlsson, Adam N. Nilsson, Diana Serrano +5

We perform hole burning with a low drift stabilized laser within the zero phonon line of the 4f-5d transition in Ce $^{3 +}$ :Y $_{2}$ SiO $_{5}$ at 2K. The narrowest spectral holes appear f…
