Parametric amplification by coupled flux qubits
M. Rehak, P. Neilinger, M. Grajcar +4
We report the parametric amplification of a microwave signal in a Kerr medium formed from superconducting qubits. Two mutually coupled flux qubits, embedded in the current antinode…
Implementation of a Quantum Metamaterial
Pascal Macha, Gregor Oelsner, Jan-Michael Reiner +7
Manipulating the propagation of electromagnetic waves through sub-wavelength sized artificial structures is the core function of metamaterials. Resonant structures, such as split r…
Amplification and attenuation of a probe signal by doubly-dressed states
S. N. Shevchenko, G. Oelsner, Ya. S. Greenberg +6
We analyse a system composed of a qubit coupled to electromagnetic fields of two high quality quantum oscillators. Particular realization of such a system is the superconducting qu…
