On-Chip Microwave Fock States and Quantum Homodyne Measurements
M. Mariantoni, M. J. Storcz, F. K. Wilhelm +6
We propose a method to couple metastable flux-based qubits to superconductive resonators based on a quantum-optical Raman excitation scheme that allows for the deterministic genera…
Intrinsic phonon decoherence and quantum gates in coupled lateral quantum dot charge qubits
Markus J. Storcz, Udo Hartmann, Sigmund Kohler +1
Recent experiments by Hayashi et al. [Phys. Rev. Lett. 91, 226804 (2003)] demonstrate coherent oscillations of a charge quantum bit (qubit) in laterally defined quantum dots. We st…
Efficient readout of flux qubits at degeneracy
A. Kack, F. K. Wilhelm
We present a superconducting circuit consisting of a flux qubit and a single-charge transistor serving as a detector. As flux and charge are conjugate, the transistor can detect st…
Strong coupling of a qubit to shot noise
Udo Hartmann, Frank K. Wilhelm
We perform a nonperturbative analysis of a charge qubit in a double quantum dot structure coupled to its detector. We show that strong detector-dot interaction tends to slow down a…
Decoherence of a two-qubit system with a variable bath coupling operator
Markus J. Storcz, Frank Hellmann, Calin Hrelescu +1
We examine the decoherence of an asymmetric two-qubit system that is coupled via a tunable interaction term to a common bath or two individual baths of harmonic oscillators. The di…
Ohmic and step noise from a single trapping center hybridized with a Fermi sea
Rogerio de Sousa, K. Birgitta Whaley, Frank K. Wilhelm +1
We show that single electron tunneling devices such as the Cooper-pair box or double quantum dot can be sensitive to the zero-point fluctuation of a single trapping center hybridiz…
