An ultracompact dilution refrigerator for fast quantum device characterization
Clment Geffroy, Dorian Nicolas, Eric Eyraud +10
Rapid thermal cycling is a central bottleneck in the development of superconducting quantum devices: conventional dilution refrigerators require cooldowns of a day or more and subs…
Suppression of measurement-induced state transitions in cosϕ-coupling transmon readout
Cyril Mori, Francesca D Esposito, Alexandru Petrescu +12
Drive-induced unwanted state transitions (DUST) are limiting both for microwave readout and parametric operations of superconducting qubits. Among them, measurement-induced state t…
High-power readout of a transmon qubit using a nonlinear coupling
Cyril Mori, Vladimir Milchakov, Francesca D'Esposito +13
The field of superconducting qubits is constantly evolving with new circuit designs. However, when it comes to qubit readout, the use of simple transverse linear coupling remains o…
Using bi-fluxon tunneling to protect the Fluxonium qubit
Waël Ardati, Sébastien Léger, Shelender Kumar +8
Encoding quantum information in quantum states with disjoint wave-function support and noise insensitive energies is the key behind the idea of qubit protection. While fully protec…
