Nondestructive readout for a superconducting flux qubit.

We present a new readout method for a superconducting flux qubit, based on the measurement of the Josephson inductance of a superconducting quantum interference device that is inductively coupled to the qubit. The intrinsic flux detection efficiency and backaction are suitable for a fast and nondestructive determination of the quantum state of the qubit, as needed for readout of multiple qubits...

Strategies for Measuring the Decoherence Time of a Superconducting Qubit

The major roadblock to the development of a useful superconducting quantum coherent bit is decoherence. Integrating a flux-based qubit with Rapid Single Flux Quantum (RSFQ) electronics on a monolithic circuit provides a means to quickly prepare and measure the state of the qubit, thus enabling a number of qubit manipulations and interactions to take place within the qubit coherence time. Howeve...

Decoherence of a superconducting qubit due to bias noise

We calculate for the current-biased Josephson junction the decoherence of the qubit state from noise and dissipation. The effect of dissipation can be entirely accounted for through a semiclassical noise model that appropriately includes the effect of zero-point and thermal fluctuations from dissipation. The magnitude and frequency dependence of this dissipation can be fully evaluated with this...
