Journal ArticleDOI
Multimode entanglement in reconfigurable graph states using optical frequency combs
Yin Cai,Jonathan Roslund,Giulia Ferrini,Giulia Ferrini,Francesco Arzani,Xinye Xu,Claude Fabre,Nicolas Treps +7 more
TL;DR: An optical on-demand, reconfigurable multimode entangled state, using an intrinsically multimode quantum resource and a homodyne detection apparatus is demonstrated, which enables the interrogation of quantum correlations and fluctuations for any multimode Gaussian state.
Journal ArticleDOI
Number squeezing, quantum fluctuations and oscillations in mesoscopic Bose Josephson junctions
TL;DR: In this article, the ground state and dynamical evolution for a Bose Josephson junction realized by an ultracold Bose gas in a double-well trap were determined using a twomode Bose-Hubbard Hamiltonian.
Journal ArticleDOI

TL;DR: In this paper, a quantum approximate optimization algorithm was implemented on a hardware platform, consisting of two superconducting transmon qubits and one parametrically modulated coupler.
Journal ArticleDOI
Full characterization of a highly multimode entangled state embedded in an optical frequency comb using pulse shaping
TL;DR: In this article, a detailed analysis of the multimode quantum state embedded in an optical frequency comb generated by a Synchronously Pumped Optical Parametric Oscillator (SPOPO) is presented.
Journal ArticleDOI

TL;DR: This proof is extended to the continuous-variable (CV) domain by using squeezed states and homodyne detection, and by exploring the properties of postselected circuits, showing that, in order to render postselected computational classes in CVs meaningful, a logarithmic scaling of the squeezing parameter with the circuit size is necessary.
