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…
Controllable interaction between photons and distant spins via vacuum Rabi oscillations
Xiao Xue, Jurgen Dijkema, Tobias Bonsen +7
Vacuum Rabi oscillations between a single photon and a single spin demonstrate the capability of harnessing light-matter interaction at the level of a single quantum of energy. Sin…
From Characterization To Construction: Generative Quantum Circuit Synthesis from Gate Set Tomography Data
King Yiu Yu, Aritra Sarkar, Erbing Hua +3
High-fidelity circuit execution on noisy intermediate-scale quantum devices is bottlenecked by compilation pipelines that disregard complex, correlated noise. To address this, this…
Suppressing spin qubit decoherence during shuttling via confinement modulation
Daniel Q. L. Nguyen, Maximilian Rimbach-Russ, Stefano Bosco
Reliable long-range qubit shuttling is a powerful tool for scalable quantum computing architectures. We investigate strategies to improve the coherence of moving spin qubits by per…
g-tensor Optimization in Ge/SiGe Quantum Dots
Aram Shojaei, Edmondo Valvo, Maximilian Rimbach-Russ +2
Planar germanium heterostructures hosting hole-spin qubits are among the leading platforms for scalable semiconductor-based quantum computing. Yet, device performance is hindered b…
Probing Electrostatic Disorder via g-Tensor Geometry
Edmondo Valvo, Christian Ventura-Meinersen, Michele Jakob +3
Low-frequency charge noise induced by fluctuating electrostatic disorder is a major limitation for semiconductor hole spin qubits. Here, we analyze the quasistatic response of a ho…
