Ballistic supercurrent discretization and micrometer-long Josephson coupling in germanium
N. W. Hendrickx, M. L. V. Tagliaferri, M. Kouwenhoven +6
We fabricate Josephson field-effect-transistors in germanium quantum wells contacted by superconducting aluminum and demonstrate supercurrents carried by holes that extend over jun…
Impact of valley phase and splitting on readout of silicon spin qubits
M. L. V. Tagliaferri, P. L. Bavdaz, W. Huang +3
We investigate the effect of the valley degree of freedom on Pauli-spin blockade readout of spin qubits in silicon. The valley splitting energy sets the singlet-triplet splitting a…
Spin lifetime and charge noise in hot silicon quantum dot qubits
L. Petit, J. M. Boter, H. G. J. Eenink +10
We investigate the magnetic field and temperature dependence of the single-electron spin lifetime in silicon quantum dots and find a lifetime of 2.8 ms at a temperature of 1.1 K. W…
Gate-controlled quantum dots and superconductivity in planar germanium
N. W. Hendrickx, D. P. Franke, A. Sammak +9
Superconductors and semiconductors are crucial platforms in the field of quantum computing. They can be combined to hybrids, bringing together physical properties that enable the d…
