Abstract
A method for performing a quantum computing entanglement operation between a phase qubit and a charge qubit. A coherent connection between the phase qubit and the charge qubit is provided. The coherent connection allows the quantum state of the phase qubit and the quantum state of the charge qubit to interact with each other. The coherent connection is modulated for a duration te. The phase qubit is connected to the charge qubit during at least a portion of the duration te in order to controllably entangle the quantum state of the phase qubit and the quantum state of the charge qubit.
