Quantum computing and artificial intelligence: status and perspectives
Giovanni Acampora, Andris Ambainis, Natalia Ares +36
This white paper discusses and explores the various points of intersection between quantum computing and artificial intelligence (AI). It describes how quantum computing could supp…
High-Fidelity Electron Spin Gates for Scaling Diamond Quantum Register
Timo Joas, Florian Ferlemann, Roberto Sailer +9
Diamond is a promising platform for quantum information processing as it can host highly coherent qubits that could allow for the construction of large quantum registers. A prerequ…
Circuit Design for a Star-shaped Spin-Qubit Processor via Algebraic Decomposition and Optimal Control
Yaqing X. Wang, Tommaso Calarco, Felix Motzoi +1
As quantum processing units grow in size and precision we enter the stage where quantum algorithms can be tested on actual quantum devices. To implement a given quantum circuit on…
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…
