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…
Experimental error suppression in Cross-Resonance gates via multi-derivative pulse shaping
Boxi Li, Tommaso Calarco, Felix Motzoi
While quantum circuits are reaching impressive widths in the hundreds of qubits, their depths have not been able to keep pace. In particular, cloud computing gates on multi-qubit,…
