| 中文摘要 | We present a potential scheme to implement two-qubit quantum phase gates through an unconventional geometric phase shift with two four-level SQUIDs in a cavity. The SQUID qubits undergo no transitions during the gate operation, while the cavity mode is displaced along a circle in the phase space, acquiring a geometric phase depending conditionally upon the SQUIDs' states. Under certain conditions, the SQUID qubits are disentangled with the cavity mode and the SQUIDs' states remain in their ground states during the gate operation, thus the gate is insensitive to both the SQUIDs' "spontaneous emission" and the cavity decay.
