Immittance formulas for exact blackbox quantization and divergence-free effective models in circuit QED
Philippe Gigon, Peter Rabl, Adrian Parra-Rodriguez
Building on the first-order circuit quantization method [arXiv:2304.12252, arXiv:2401.09120], we provide simple formulas to construct exact Hamiltonians for Josephson-junction-base…
Driven two-level systems as a minimal resource for remote entanglement stabilization
Philippe Gigon, Adrian Parra-Rodriguez, Joan Agustí +1
We analyze the autonomous stabilization of remote entanglement by driving two distant qubits with the output of a correlated photon source. By treating the qubits as idealized enta…
Floquet Topological Frequency-Converting Amplifier
Adrian Parra-Rodriguez, Miguel Clavero-Rubio, Philippe Gigon +3
We introduce a driven-dissipative Floquet model in which a single harmonic oscillator, with both frequency and decay rate modulated, realizes a non-Hermitian synthetic lattice with…
Probing excited-state dynamics of transmon ionization
Zihao Wang, Benjamin D'Anjou, Philippe Gigon +2
The fidelity and quantum nondemolition character of the dispersive readout in circuit QED are limited by unwanted transitions to highly excited states at specific photon numbers in…
