Automated electrostatic characterization of quantum dot devices in single- and bilayer heterostructures
Merritt P. R. Losert, Dario Denora, Barnaby van Straaten +6
As quantum dot (QD)-based spin qubits advance toward larger, more complex device architectures, rapid, automated device characterization and data analysis tools become critical. Th…
Towards autonomous time-calibration of large quantum-dot devices: Detection, real-time feedback, and noise spectroscopy
Anantha S. Rao, Barnaby van Straaten, Valentin John +8
The performance and scalability of semiconductor quantum-dot (QD) qubits are limited by electrostatic drift and charge noise that shift operating points and destabilize qubit param…
A Three-Dimensional Array of Quantum Dots
Hanifa Tidjani, Dario Denora, Michael Chan +6
Quantum dots can confine single electrons or holes to define spin qubits that can be operated with high fidelity. Experimental work has progressed from linear to two-dimensional ar…
Distributing entanglement between distant semiconductor qubit registers using a shared-control shuttling link
Zarije Ademi, Marion Bassi, Cécile X. Yu +8
Semiconductor quantum processors have potential to scale to modular quantum computers, in which qubit registers are coupled by quantum links, enabling high connectivity and space f…
Optimising germanium hole spin qubits with a room-temperature magnet
Cecile X. Yu, Barnaby van Straaten, Alexander S. Ivlev +6
Germanium spin qubits exhibit strong spin-orbit interaction, which allow for high-fidelity qubit control, but also provide a strong dependence on the magnetic field. Superconductin…
Site-resolved magnon and triplon dynamics on a programmable quantum dot spin ladder
Pablo Cova Fariña, Daniel Jirovec, Xin Zhang +7
Quasi-particle dynamics in interacting systems in the presence of disorder challenges the notion of internal thermalization, but proves difficult to investigate theoretically for l…
