Fermion parity of an Andreev molecule probed by nonlocal Josephson effect
S. Annabi, H. Riechert, K. Watanabe +5
Fermion parity is a fundamental property of superconducting many-body states. Here, we show that the global fermion parity of a delocalized superconducting state can be detected lo…

Towards a Josephson element using aluminum junctions with well-transmitted channels
J. Griesmar, H. Riechert, M. Hantute +8
We introduce a novel method for fabricating all-aluminum Josephson junctions with highly transmitted conduction channels. Such properties are typically associated with structures r…

The carbon nanotube gatemon qubit
H. Riechert, S. Annabi, A. Peugeot +8
Gate-tunable transmon qubits are based on quantum conductors used as weak links within hybrid Josephson junctions. These gatemons have been implemented in just a handful of systems…
