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…
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…
Bang-Bang refocusing of a qubit exposed to telegraph noise
H. Gutmann, F. K. Wilhelm, W. M. Kaminsky +1
We investigate the decoherence effect of telegraph noise on a single qubit, usually provoked by bistable fluctuators. To diminish the dephasing and relaxation impact an effective r…
Compensation of decoherence from telegraph noise by means of bang-bang control
H. Gutmann, F. K. Wilhelm, W. M. Kaminsky +1
With the growing efforts in isolating solid-state qubits from external decoherence sources, the origins of noise inherent to the material start to play a relevant role. One represe…
