Converting single photons from an InAs/GaAs quantum dot into the ultraviolet: preservation of second-order correlations
Anica Hamer, David Fricker, Marcel Hohn +6
Wavelength conversion at the single-photon level is required to forge a quantum network from distinct quantum devices. Such devices include solid-state emitters of single or entang…
The connection between time-local and time-nonlocal perturbation expansions
K. Nestmann, M. R. Wegewijs
There exist two canonical approaches to describe open quantum systems by a time-evolution equation: the Nakajima-Zwanzig quantum master equation, featuring a time-nonlocal memory k…
Quantum Annealing with Trigger Hamiltonians: Application to 2-SAT and Nonstoquastic Problems
Vrinda Mehta, Fengping Jin, Hans De Raedt +1
We study the performance of quantum annealing for two sets of problems, namely, 2-satisfiability (2-SAT) problems represented by Ising-type Hamiltonians, and nonstoquastic problems…
Modelling for Quantum Error Mitigation
Tom Weber, Matthias Riebisch, Kerstin Borras +2
While we expect quantum computers to surpass their classical counterparts in the future, current devices are prone to high error rates and techniques to minimise the impact of thes…
