Spatial uniformity of g-tensor and spin-orbit interaction in germanium hole spin qubits
Inga Seidler, Bence Hetényi, Lisa Sommer +12
Holes in Ge/SiGe heterostructures are now a leading platform for semiconductor spin qubits, thanks to the high confinement quality, two-dimensional arrays, high tunability, and lar…
A dressed singlet-triplet qubit in germanium
Konstantinos Tsoukalas, Uwe von Lüpke, Alexei Orekhov +15
In semiconductor hole spin qubits, low magnetic field () operation extends the coherence time () but proportionally reduces the gate speed. In contrast, singlet-…
Identifying and mitigating errors in hole spin qubit readout
Eoin Gerard Kelly, Leonardo Massai, Bence Hetényi +14
High-fidelity readout of spin qubits in semiconductor quantum dots can be achieved by combining a radio-frequency (RF) charge sensor together with spin-to-charge conversion and Pau…
Capacitive crosstalk in gate-based dispersive sensing of spin qubits
Eoin G. Kelly, Alexei Orekhov, Nico Hendrickx +8
In gate-based dispersive sensing, the response of a resonator attached to a quantum dot gate is detected by a reflected radio-frequency signal. This enables fast readout of spin qu…
Resonant two-qubit gates for fermionic simulations with spin qubits
Konstantinos Tsoukalas, Alexei Orekhov, Bence Hetényi +15
In gate-defined semiconductor spin qubits, the highly tunable Heisenberg exchange interaction is leveraged to implement fermionic two-qubit gates such as CZ and SWAP. However, the…
A portable potentiometric electronic tongue leveraging smartphone and cloud platforms
Patrick W. Ruch, Rui Hu, Luca Capua +7
Electronic tongues based on potentiometry offer the prospect of rapid and continuous chemical fingerprinting for portable and remote systems. The present contribution presents a te…
