Claim 9:
10. A method for reading out a state of a qubit, the method comprising:
injecting a readout input waveform into a system that comprises an information storage element for storing the state of the qubit and a readout resonator that is electromagnetically coupled to said information storage element; and
detecting a readout output waveform extracted from said system,
wherein said injecting of the readout input waveform takes place through an excitation port that is also used to inject excitation waveforms to the information storage element for affecting the state of the qubit, and simultaneously through a first readout port that is different than said excitation port, and
wherein a phase of the readout input waveform is controllably shifted in the course of injecting it into the system.
