A Degenerate Singlet-Triplet Qubit with All-Electrical Orthogonal Control
Phuong X. Nguyen, Konstantinos Tsoukalas, Jann H. Ungerer +8
The paper demonstrates an all‑electrical method to achieve orthogonal control of a degenerate singlet‑triplet qubit formed by two hole spins in a germanium double quantum dot, enab…
Large quantum dot energy level shifts in anomalous photon-assisted tunneling
Jared Benson, C. E. Sturner, A. R. Huffman +12
Orbital energy splittings are important quantum dot parameters for the operation of hole spin qubits. They are known to depend on the lateral confinement of the quantum dots. Howev…
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…
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…
Modular Autonomous Virtualization System for Two-Dimensional Semiconductor Quantum Dot Arrays
Anantha S. Rao, Donovan Buterakos, Barnaby van Straaten +8
Arrays of gate-defined semiconductor quantum dots are among the leading candidates for building scalable quantum processors. High-fidelity initialization, control, and readout of s…
A two-dimensional 10-qubit array in germanium with robust and localised qubit control
Valentin John, Cécile X. Yu, Barnaby van Straaten +10
Quantum computers require the systematic operation of qubits with high fidelity. For holes in germanium, the spin-orbit interaction allows for \textit{in situ} electric fast and hi…
