Quantum Dynamics of Kerr Optical Frequency Combs below and above Threshold: Spontaneous Four-Wave-Mixing, Entanglement and Squeezed States of Light
Yanne K. Chembo
In this article, we use quantum Langevin equations to provide a theoretical understanding of the non-classical behavior of Kerr optical frequency combs when pumped below and above…
Overcoming efficiency constraints on blind quantum computation
Carlos A. Pérez-Delgado, Joseph F. Fitzsimons
Blind quantum computation allows a user to delegate a computation to an untrusted server while keeping the computation hidden. A number of recent works have sought to establish bou…
Comparing different approaches for generating random numbers device-independently using a photon pair source
V. Caprara Vivoli, P. Sekatski, J. -D. Bancal +6
What is the most efficient way to generate random numbers device-independently using a photon pair source based on spontaneous parametric down conversion (SPDC)? We consider this q…
Creation of quantum error correcting codes in the ultrastrong coupling regime
T. H. Kyaw, D. A. Herrera-Martı, E. Solano +2
We propose to construct large quantum graph codes by means of superconducting circuits working at the ultrastrong coupling regime. In this physical scenario, we are able to create…
Quantum chimera states
David Viennot, Lucile Aubourg
We study a theoretical model of closed quasi-hermitian chain of spins which exhibits quantum analogues of chimera states, i.e. long life classical states for which a part of an osc…
Reversing the temporal envelope of a heralded single photon using a cavity
Bharath Srivathsan, Gurpreet Kaur Gulati, Alessandro Cerè +2
We demonstrate a way to prepare single photons with a temporal envelope that resembles the time reversal of photons from the spontaneous decay process. We use the photon pairs gene…
