Cavity driven by a single photon: conditional dynamics and non-linear phase shift
A. R. R. Carvalho, M. R. Hush, M. R. James
We apply the stochastic master equations (quantum filter) derived by Gough et al. (Proc. 50th IEEE Conference on Decision and Control, 2011) to a system consisting of a cavity driv…
On the response of quantum linear systems to single photon input fields
Guofeng Zhang, Matthew R. James
The purpose of this paper is to extend linear systems and signals theory to include single photon quantum signals. We provide detailed results describing how quantum linear systems…
A quantum algorithm for obtaining the lowest eigenstate of a Hamiltonian assisted with an ancillary qubit system
Jeongho Bang, Seung-Woo Lee, Chang-Woo Lee +1
We propose a quantum algorithm to obtain the lowest eigenstate of any Hamiltonian simulated by a quantum computer. The proposed algorithm begins with an arbitrary initial state of…
Photonic Boson Sampling in a Tunable Circuit
Matthew A. Broome, Alessandro Fedrizzi, Saleh Rahimi-Keshari +4
Quantum computers are unnecessary for exponentially-efficient computation or simulation if the Extended Church-Turing thesis---a foundational tenet of computer science---is correct…
Surface code with decoherence: An analysis of three superconducting architectures
Joydip Ghosh, Austin G. Fowler, Michael R. Geller
We consider realistic, multi-parameter error models and investigate the performance of the surface code for three possible fault-tolerant superconducting quantum computer architect…
Testing genuine multipartite nonlocality in phase space
Seung-Woo Lee, Mauro Paternostro, Jinhyoung Lee +1
We demonstrate genuine three-mode nonlocality based on phase space formalism. A Svetlichny-type Bell inequality is formulated in terms of the -parameterized quasiprobability fun…
