Electrically Tuneable Variability in Germanium Hole Spin Qubits
Edmondo Valvo, Michele Jakob, Patrick Del Vecchio +2
Hole spin qubits in planar germanium heterostructures are frontrunners for scalable semiconductor quantum computing. However, their current performance is mostly limited by large d…
Dissipation in passive non-reciprocal microwave devices
Stefano Bosco
Non-reciprocal devices are key components in both classical and quantum electronics. One approach to realizing passive non-reciprocal microwave devices is through capacitive coupli…
Spin-orbit-enabled realization of arbitrary two-qubit gates on moving spins
D. Fernández-Fernández, Y. Matsumoto, L. M. K. Vandersypen +2
Shuttling spin qubits in systems with large spin-orbit interaction (SOI) can cause errors during motion. However, in this work, we demonstrate that SOI can be harnessed to implemen…
Fast readout of quantum dot spin qubits via Andreev spins
Michèle Jakob, Katharina Laubscher, Patrick Del Vecchio +3
Spin qubits in semiconducting quantum dots are currently limited by slow readout processes, which are orders of magnitude slower than gate operations. In contrast, Andreev spin qub…
Fully Tunable Strong Spin-Orbit Interactions in Light Hole Germanium Quantum Channels
Patrick Del Vecchio, Stefano Bosco, Daniel Loss +1
Spin-orbit interaction (SOI) is a fundamental component for electrically driven spin qubits and hybrid superconducting-semiconducting systems. In particular, Rashba SOI (RSOI) is a…
Single-step high-fidelity three-qubit gates by anisotropic chiral interactions
Minh T. P. Nguyen, Maximilian Rimbach-Russ, Lieven M. K. Vandersypen +1
Direct multi-qubit gates are becoming critical to facilitate quantum computations in near-term devices by reducing the gate counts and circuit depth. Here, we demonstrate that fast…
