Input phase noise in Gaussian Boson sampling
Magdalena Parýzková, Craig S. Hamilton, Igor Jex +2
Gaussian boson sampling is an important protocol for testing the performance of photonic quantum simulators. As such, various noise sources have been investigated that degrade the…
Quantum metrology in a nonlinear-interferometer with feedback
Shivani Singh, Craig S. Hamilton, Igor Jex
In this paper, we propose a nonlinear interferometer with feedback loops and explore its efficiency for phase estimation. We analyse two feedback schemes, one where both modes of t…
Recurrence in discrete-time quantum stochastic walks
Martin Stefanak, Vaclav Potocek, Iskender Yalcinkaya +2
Interplay between quantum interference and classical randomness can enhance performance of various quantum information tasks. In the present paper we analyze recurrence phenomena i…
Boson Sampling from Non-Gaussian States
Craig S. Hamilton, Igor Jex
Boson sampling has emerged as an important tool to demonstrate the difference between quantum and classical computers and has attracted the interest of experimentalists and theoret…
Analysis and minimization of bending losses in discrete quantum networks
G. M. Nikolopoulos, A. Hoskovec, I. Jex
We study theoretically the transfer of quantum information along bends in two-dimensional discrete lattices. Our analysis shows that the fidelity of the transfer decreases consider…
Quantum Walk with Jumps
H. Lavička, V. Potoček, T. Kiss +2
We analyze a special class of 1-D quantum walks (QWs) realized using optical multi-ports. We assume non-perfect multi-ports showing errors in the connectivity, i.e. with a small pr…
