Observation of coherent flux-charge interaction in a gate-tunable fluxonium
Brian D. Isakov, Shikhar Singh, Adrian Parra-Rodriguez +7
Interactions that mix conjugate variables, such as the flux through a circuit element and the charge across it, lie outside the reach of the elementary couplings of superconducting…
Dynamical Regimes of Finite-Length Transmission Lines in Circuit Quantum Electrodynamics
Fabio Borrelli, Giovanni Miano, Adrian Parra-Rodriguez +1
We study the emergence of continuum, discrete-multimode, and single-mode regimes in finite-length transmission lines capacitively coupled to transmon qubits. We show that the appro…
Driven two-level systems as a minimal resource for remote entanglement stabilization
Philippe Gigon, Adrian Parra-Rodriguez, Joan Agustà +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…
Exact quantization of nonreciprocal quasi-lumped electrical networks
A. Parra-Rodriguez, I. L. Egusquiza
Following a consistent geometrical description previously introduced in Parra-Rodriguez et al. (2024), we present an exact method for obtaining canonically quantizable Hamiltonian…
