Analytical solutions for optimal photon absorption into inhomogeneous spin memories
József Zsolt Bernád, Michael Schilling, Yutian Wen +4
We investigate for optimal photon absorption a quantum electrodynamical model of an inhomogeneously-broadened spin ensemble coupled to a single-mode cavity. Solutions to this probl…

Coherent Control of a Long-Lived Nuclear Memory Spin in a Germanium-Vacancy Multi-Qubit Node
Nick Grimm, Katharina Senkalla, Philipp J. Vetter +6
The ability to process and store information on surrounding nuclear spins is a major requirement for group-IV color center-based repeater nodes. We demonstrate coherent control of…

The Role of Bases in Quantum Optimal Control
Alice Pagano, Matthias M Müller, Tommaso Calarco +2
Quantum Optimal Control (QOC) supports the advance of quantum technologies by tackling its problems at the pulse level: Numerical approaches iteratively work towards a given target…
