Experimental Bayesian Quantum Phase Estimation on a Silicon Photonic Chip
Stefano Paesani,Antonio Gentile,Raffaele Santagati,Jianwei Wang,Nathan Wiebe,David P. Tew,Jeremy L. O'Brien,Mark G. Thompson +7 more
TL;DR: A recently proposed adaptive Bayesian approach to quantum phase estimation is implemented and used to simulate molecular energies on a silicon quantum photonic device and is verified to be well suited for prethreshold quantum processors by investigating its superior robustness to noise and decoherence.
Journal ArticleDOI
Experimental quantum Hamiltonian learning

TL;DR: In this paper, a quantum simulator and Bayesian inference is used to determine the unknown Hamiltonian of a quantum system using a photonic simulator and a solid-state system, which is shown to be able to characterize the operation of the quantum photonic device.
