Gate- and flux-tunable sin(2) Josephson element with proximitized Ge-based junctions
Axel Leblanc, Chotivut Tangchingchai, Zahra Sadre Momtaz +11
Hybrid superconductor-semiconductor Josephson field-effect transistors (JoFETs) function as Josephson junctions with a gate-tunable critical current. Additionally, they can feature…
Mitigating variability in epitaxial-heterostructure-based spin-qubit devices by optimizing gate layout
Biel Martinez, Silvano de Franceschi, Yann-Michel Niquet
The scalability of spin qubit devices is conditioned by qubit-to-qubit variability. Disorder in the host materials indeed affects the wave functions of the confined carriers, which…
From nonreciprocal to charge-4e supercurrents in Ge-based Josephson devices with tunable harmonic content
Axel Leblanc, Chotivut Tangchingchai, Zahra Sadre Momtaz +10
Hybrid superconductor(S)-semiconductor(Sm) devices bring a range of new functionalities into superconducting circuits. In particular, hybrid parity-protected qubits and Josephson d…
Real-time milli-Kelvin thermometry in a semiconductor qubit architecture
Victor Champain, Vivien Schmitt, Benoit Bertrand +6
We report local time-resolved thermometry in a silicon nanowire quantum dot device designed to host a linear array of spin qubits. Using two alternative measurement schemes based o…
A new FDSOI spin qubit platform with 40nm effective control pitch
T. Bédécarrats, B. Cardoso Paz, B. Martinez Diaz +19
Operating Si quantum dot (QD) arrays requires homogeneous and ultra-dense structures with aggressive gate pitch. Such a density is necessary to separately control the QDs chemical…
Strong coupling between a photon and a hole spin in silicon
Cécile X. Yu, Simon Zihlmann, José C. Abadillo-Uriel +11
Spins in semiconductor quantum dots constitute a promising platform for scalable quantum information processing. Coupling them strongly to the photonic modes of superconducting mic…
