Rapid biexciton state preparation in a quantum dot using on-off pulse-sequences
Dionisis Stefanatos, Emmanuel Paspalakis
We consider the problem of pulsed biexciton preparation in a quantum dot and show that a pulse-sequence with a simple on-off-on modulation can achieve complete preparation of the t…
Qubit-excitation-based adaptive variational quantum eigensolver
Yordan S. Yordanov, V. Armaos, Crispin H. W. Barnes +1
Molecular simulations with the variational quantum eigensolver (VQE) are a promising application for emerging noisy intermediate-scale quantum computers. Constructing accurate mole…
Performance of superadiabatic stimulated Raman adiabatic passage in the presence of dissipation and Ornstein-Uhlenbeck dephasing
Kostas Blekos, Dionisis Stefanatos, Emmanuel Paspalakis
In this paper we evaluate the performance of two superadiabatic stimulated Raman adiabatic passage (STIRAP) protocols derived from Gaussian and sin-cos pulses, under dissipation an…
Dynamical blockade in a bosonic Josephson junction using optimal coupling
Dionisis Stefanatos, Emmanuel Paspalakis
In this article we use time-dependent Josephson coupling to enhance unconventional photon blockade in a system of two coupled nonlinear bosonic modes which are initially loaded wit…
Quantum Superposition of Two Gravitational Cat States
Charis Anastopoulos, Bei-Lok Hu
We extend our earlier work on probing a gravitational cat state (gravcat)---see, arXiv:1504.03103 ---to the quantum superposition of two gravcats in an exemplary model and in Bose-…
Field assisted extraction and swelling of quantum coherence for moving Unruh-DeWitt detectors
Nikolaos K. Kollas, Dimitris Moustos, Kostas Blekos
We study the effects of motion for an Unruh-DeWitt detector, modeled as a two-level system, on the amount of coherence extracted, when it interacts with a massless scalar coherent…
