Flopping-mode electric dipole spin resonance in phosphorus donor qubits in silicon
F. N. Krauth, S. K. Gorman, Y. He +9
Single spin qubits based on phosphorus donors in silicon are a promising candidate for a large-scale quantum computer. Despite long coherence times, achieving uniform magnetic cont…
Realization of a binary-outcome projection measurement of a three-level superconducting quantum system
Markus Jerger, Pascal Macha, Andrés Rosario Hamann +3
Binary-outcome measurements allow to determine whether a multi-level quantum system is in a certain state while preserving quantum coherence between all orthogonal states. In this…
Dispersive Response of a Disordered Superconducting Quantum Metamaterial
Dmitriy S. Shapiro, Pascal Macha, Alexey N. Rubtsov +1
We consider a disordered quantum metamaterial formed by an array of superconducting flux qubits coupled to microwave photons in a cavity. We map the system on the Tavis-Cummings mo…
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…
Dressed-state amplification by a superconducting qubit
G. Oelsner, P. Macha, O. V. Astafiev +6
We demonstrate amplification of a microwave signal by a strongly driven two-level system in a coplanar waveguide resonator. The effect known from optics as dressed-state lasing is…
