Dispersive readout scheme for a Josephson phase qubit
Dispersive readout scheme Josephson phase qubit
2010/11/9
We present experimental results on a dispersive scheme for reading out a Josephson phase qubit. A capacitively shunted dc-SQUID is used as a nonlinear resonator which is inductively coupled to the qub...
Controlled-NOT logic with nonresonant Josephson phase qubits
Controlled-NOT logic nonresonant Josephson phase
2010/4/7
We establish theoretical bounds on qubit detuning for high fidelity controlled-NOT logic gate implementations with weakly coupled Josephson phase qubits. It is found that the value of qubit detuning d...
