Strategies for quantum computing molecular energies using the unitary coupled cluster ansatz
Jonathan Romero,Ryan Babbush,Jarrod R. McClean,Cornelius Hempel,Peter J. Love,Alán Aspuru-Guzik +5 more
TL;DR: In this paper, a variational quantum eigensolver (VQE) was applied to the simulation of molecular energies using the unitary coupled cluster (UCC) ansatz, and new strategies to reduce the circuit depth for the implementation of UCC and improve the optimization of the wave function based on efficient classical approximations of the cluster amplitudes.

Discrete single-photon quantum walks with tunable decoherence.
Matthew A. Broome,Alessandro Fedrizzi,Benjimain P. Lanyon,Ivan Kassal,Alán Aspuru-Guzik,Andrew White +5 more
TL;DR: In this article, the authors present an intrinsically stable, deterministic implementation of discrete quantum walks with single photons in space, and explore the quantum-to-classical transition by introducing tunable decoherence.

B. P. Lanyon,James D. Whitfield,Geoff Gillett,M. E. Goggin,Marcelo P. Almeida,Ivan Kassal,Jacob Biamonte,Jacob Biamonte,Masoud Mohseni,Masoud Mohseni,Benjamin Powell,Marco Barbieri,Alán Aspuru-Guzik,Andrew White +13 more
TL;DR: In this article, the authors reported the application of the latest photonic quantum computer technology to calculate properties of the smallest molecular system: the hydrogen molecule in a minimal basis, and discussed how the technique can be expanded to solve large-scale chemical problems that lie beyond the reach of modern supercomputers.
