Variable-frequency-controlled coupling in charge qubit circuits: Effects of microwave field on qubit-state readout
arXiv:quant-ph/0703147 · doi:10.1103/PhysRevA.76.022317
Abstract
To implement quantum information processing, microwave fields are often used to manipulate superconuducting qubits. We study how the coupling between superconducting charge qubits can be controlled by variable-frequency magnetic fields. We also study the effects of the microwave fields on the readout of the charge-qubit states. The measurement of the charge-qubit states can be used to demonstrate the statistical properties of photons.
