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…
Quantized resonator field coupled to a current-biased Josephson junction in circuit QED
Christian Kraglund Andersen, Gregor Oelsner, Evgeni Il'ichev +1
A Lagrangian formalism is used to derive the Hamiltonian for a /4 resonator shunted by a current-biased Josephson junction. The eigenstates and the quantum dynamics of the syste…
Electromagnetically induced transparency and Autler-Townes splitting in superconducting flux quantum circuits
Hui-Chen Sun, Yu-xi Liu, J. Q. You +2
We study the microwave absorption of a driven three-level quantum system, which is realized by a superconducting flux quantum circuit (SFQC), with a magnetic driving field applied…
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…
Phase diagram of the resistive state of the narrow superconducting channel in the voltage-driven regime
Y. S. Yerin, V. N. Fenchenko, E. Il'ichev
Based on the numerical solution non-stationary Ginzburg-Landau equations, we investigated the evolution of the order parameter of superconducting channels with different lengths un…
Validation of Soft Classification Models using Partial Class Memberships: An Extended Concept of Sensitivity & Co. applied to the Grading of Astrocytoma Tissues
Claudia Beleites, Reiner Salzer, Valter Sergo
We use partial class memberships in soft classification to model uncertain labelling and mixtures of classes. Partial class memberships are not restricted to predictions, but may a…
