TL;DR: This paper uses the quantum approximate optimization algorithm in conjunction with a gradient-free Bayesian optimization to train the quantum machine, and finds evidence that classical optimization can be used to train around both coherent and incoherent imperfections.

Measures of Quantum Synchronization in Continuous Variable Systems
Andrea Mari,Alessandro Farace,Nicolas Didier,Nicolas Didier,Vittorio Giovannetti,Rosario Fazio +5 more
TL;DR: Two different measures which quantify the level of synchronization of coupled continuous variable quantum systems are introduced and they allow us to extend to the quantum domain the notions of complete and phase synchronization.

TL;DR: In this article, the authors show that parametric coupling techniques can be used to generate selective entangling interactions for multi-qubit processors by inducing coherent population exchange between adjacent qubits under frequency modulation.
Journal ArticleDOI
Fast Quantum Nondemolition Readout by Parametric Modulation of Longitudinal Qubit-Oscillator Interaction.
TL;DR: This work shows how to realize fast and high-fidelity quantum nondemolition qubit readout using longitudinal qubit-oscillator interaction, and presents an implementation of this longitudinal parametric readout in circuit quantum electrodynamics and a possible multiqubit architecture.
