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…
Universal bound on microwave dissipation in superconducting circuits
Thibault Charpentier, Anton Khvalyuk, Lev Ioffe +3
Improving the coherence of superconducting qubits is essential for advancing quantum technologies. While superconductors are theoretically perfect conductors, they consistently exh…
Theory of the photonic Joule effect in superconducting circuits
Samuel Cailleaux, Quentin Ficheux, Nicolas Roch +1
When a small system is coupled to a bath, it is generally assumed that the state of the bath remains unaffected by the system due to the bath's large number of degrees of freedom.…
First-order quantum breakdown of superconductivity in amorphous superconductors
Thibault Charpentier, David Perconte, Sébastien Léger +10
Continuous quantum phase transitions are widely assumed and frequently observed in various systems of quantum particles or spins. Their characteristic trait involves scaling laws g…
Magnetic-field dependence of a Josephson traveling-wave parametric amplifier and integration into a high-field setup
L. M. Janssen, G. Butseraen, J. Krause +6
We investigate the effect of magnetic field on a photonic-crystal Josephson traveling-wave parametric amplifier (TWPA). We show that the observed change in photonic bandgap and pla…
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…
Near-power-law temperature dependence of the superfluid stiffness in strongly disordered superconductors
Anton V. Khvalyuk, Thibault Charpentier, Nicolas Roch +2
In BCS superconductors, the superfluid stiffness is virtually constant at low temperature and only slightly affected by the exponentially low density of thermal quasiparticles. Her…
