Input-output description of microwave radiation in the dynamical Coulomb blockade
Juha Leppäkangas, Göran Johansson, Michael Marthaler +1
We study microwave radiation emitted by a small voltage-biased Josephson junction connected to a superconducting transmission line. An input-output formalism for the radiation fiel…
Effects of quasiparticle tunneling in a circuit-QED realization of a strongly driven two-level system
J. Leppäkangas, S. E. de Graaf, A. Adamyan +5
We experimentally and theoretically study the frequency shift of a driven cavity coupled to a superconducting charge qubit. In addition to previous studies, we here also consider d…
Proposal for a coherent quantum memory for propagating microwave photons
M. Afzelius, N. Sangouard, G. Johansson +2
We describe a multi-mode quantum memory for propagating microwave photons that combines a solid-state spin ensemble resonantly coupled to a frequency tunable single-mode microwave…
