Optimal collection of radiation emitted by a trapped atomic ensemble
A. Kurkó, P. Domokos, A. Vukics +4
Trapped atomic ensembles are convenient systems for quantum information storage in the long-lived sublevels of the electronic ground state and its conversion to propagating optical…

Reducing the amount of single-qubit rotations in VQE and related algorithms
S. E. Rasmussen, N. J. S. Loft, T. Bækkegaard +2
With the advent of hybrid quantum classical algorithms using parameterized quantum circuits the question of how to optimize these algorithms and circuits emerges. In this paper we…

Realization of efficient quantum gates with a superconducting qubit-qutrit circuit
T. Bækkegaard, L. B. Kristensen, N. J. S. Loft +3
Building a quantum computer is a daunting challenge since it requires good control but also good isolation from the environment to minimize decoherence. It is therefore important t…
