The role of damping for the driven anharmonic quantum oscillator
Lingzhen Guo, Michael Marthaler, Stephan André +1
For the model of a linearly driven quantum anharmonic oscillator, the role of damping is investigated. We compare the position of the stable points in phase space obtained from a c…
Strong coupling of spin qubits to a transmission line resonator
Pei-Qing Jin, Michael Marthaler, Alexander Shnirman +1
We propose a mechanism for coupling spin qubits formed in double quantum dots to a superconducting transmission line resonator. Coupling the resonator to the gate controlling the i…
Sub-Poissonian photon statistics in a strongly coupled single-qubit laser
M. Marthaler, Pei-Qing Jin, Juha Leppäkangas +1
We investigate qubit lasing in the strong coupling limit. The qubit is given by a Cooper-pair box, and population inversion is established by an additional third state, which can b…
Pure dephasing in flux qubits due to flux noise with spectral density scaling as
S. M. Anton, C. Müller, J. S. Birenbaum +10
For many types of superconducting qubits, magnetic flux noise is a source of pure dephasing. Measurements on a representative dc superconducting quantum interference device (SQUID)…
Dual-probe decoherence microscopy: Probing pockets of coherence in a decohering environment
Jan Jeske, Jared H. Cole, Clemens Müller +2
We study the use of a pair of qubits as a decoherence probe of a non-trivial environment. This dual-probe configuration is modelled by three two-level-systems which are coupled in…
Correlation between lasing and transport properties in a quantum dot-resonator system
Pei-Qing Jin, Michael Marthaler, Jared H. Cole +4
We study a double quantum dot system coherently coupled to an electromagnetic resonator. By suitably biasing the system, a population inversion can be created between the dot level…
