Coherent and ultra-low-power EDSR with a flopping-mode spin qubit in germanium
Alexei Orekhov, Wonjin Jang, Pan Zhang +13
Hole spin qubits in semiconductor quantum dots (QDs) enable high-fidelity all-electric control, but conventional electric dipole spin resonance (EDSR) can require substantial rf dr…
Light-Hole Spin Qubits in Strained SiGe Lattice-Matched to Ge

Strained germanium (-Ge) quantum wells on metamorphic SiGe buffers have enabled advanced hole-based spin qubit devices. Alternatively, unstrained Ge with lattice-match…
Disassembling qLDPC codes for depth-optimal parity-check circuits
Minh T. P. Nguyen, Maximilian Rimbach-Russ, Stefano Bosco
Quantum low-density parity-check (qLDPC) codes offer a promising route to scalable fault-tolerant quantum computing, but their practical implementation requires efficient circuits…
Geometric signatures of the onset of many-body ergodicity
Chris Ventura-Meinersen, Edmondo Valvo, Stefano Bosco +2
Identifying universal, robust, and interpretable signatures of the onset of ergodicity remains a major challenge. The adiabatic gauge potential has been noted to act as a sensitive…
