Simulating nonlocal no-signaling boxes
Mátyás Koniorczyk, Péter Naszvadi, András Bodor +3
We present a computer framework to simulate two-party boxes that exhibit nonclassical no-signaling correlations through a Web-based application programming interface (RESTful Web A…
Self-consistent quantum measurement tomography based on semidefinite programming
Marco Cattaneo, Matteo A. C. Rossi, Keijo Korhonen +4
We propose an estimation method for quantum measurement tomography (QMT) based on semidefinite programming (SDP), and discuss how it may be employed to detect experimental imperfec…
The Bonsai algorithm: grow your own fermion-to-qubit mapping
Aaron Miller, Zoltán Zimborás, Stefan Knecht +2
Fermion-to-qubit mappings are used to represent fermionic modes on quantum computers, an essential first step in many quantum algorithms for electronic structure calculations. In t…
Analytical evaluation of the coefficients of the Hu-Paz-Zhang master equation: Ohmic spectral density, zero temperature, and consistency check
G. Homa, J. Z. Bernád, A. Csordás
We investigate the exact master equation of Hu, Paz, and Zhang for a quantum harmonic oscillator at zero temperature with a Lorentz-Drude type Ohmic spectral density. This master e…
No-local-broadcasting theorem for non-signalling behaviours and assemblages
Adrian Solymos, Carlos Vieira, Cristhiano Duarte +1
The no-broadcasting theorem is a fundamental result in quantum information theory. It guarantees that a class of attacks on quantum protocols, based on eavesdropping and indiscrimi…
Highly optimized quantum circuits synthesized via data-flow engines
Peter Rakyta, Gregory Morse, Jakab Nádori +3
The formulation of quantum programs in terms of the fewest number of gate operations is crucial to retrieve meaningful results from the noisy quantum processors accessible these da…
