Automated in situ optimization and disorder mitigation in a quantum device
Jacob Benestad, Torbjørn Rasmussen, Bertram Brovang +9
We investigate automated in situ optimization of the potential landscape in a quantum point contact device, using a gate array patterned atop the constriction. Optimiz…
Autonomous Bootstrapping of Quantum Dot Devices
Anton Zubchenko, Danielle Middlebrooks, Torbjørn Rasmussen +4
Semiconductor quantum dots (QDs) are a promising platform for multiple different qubit implementations, all of which are voltage controlled by programmable gate electrodes. However…
Data needs and challenges for quantum dot devices automation
Justyna P. Zwolak, Jacob M. Taylor, Reed W. Andrews +17
Gate-defined quantum dots are a promising candidate system for realizing scalable, coupled qubit systems and serving as a fundamental building block for quantum computers. However,…
Real-time two-axis control of a spin qubit
Fabrizio Berritta, Torbjørn Rasmussen, Jan A. Krzywda +9
Optimal control of qubits requires the ability to adapt continuously to their ever-changing environment. We demonstrate a real-time control protocol for a two-electron singlet-trip…
Autonomous estimation of high-dimensional Coulomb diamonds from sparse measurements
Anasua Chatterjee, Fabio Ansaloni, Torbjørn Rasmussen +5
Quantum dot arrays possess ground states governed by Coulomb energies, utilized prominently by singly occupied quantum dots, each implementing a spin qubit. For such quantum proces…
Estimation of Convex Polytopes for Automatic Discovery of Charge State Transitions in Quantum Dot Arrays
Oswin Krause, Torbjørn Rasmussen, Bertram Brovang +2
In spin based quantum dot arrays, material or fabrication imprecisions affect the behaviour of the device, which must be taken into account when controlling it. This requires measu…
Gate reflectometry in dense quantum dot arrays
Fabio Ansaloni, Heorhii Bohuslavskyi, Federico Fedele +12
Silicon quantum devices are maturing from academic single- and two-qubit devices to industrially-fabricated dense quantum-dot (QD) arrays, increasing operational complexity and the…
