- Abstract:
- A scheme to generate a geometric phase gate is proposed in circuit quantum electrodynamics(QED)based on transmons dispersively coupled to a transmission line resonator(TLR). Gate generation can be finished before the relaxation and dephasing of the qubits, which ensures the feasibility of the proposed scheme.
