提出了一种在腔QED中用一个量子位酉门和$N$-量子位$(N确保数学2)$位相门实现几何量子计算的方案。在该方案中，通过适当控制原子-光场耦合和工程绝热通道来虚拟激发腔场和激发态，从而使门操作对腔衰变和原子自发辐射不敏感。此外，$N$-QUBIT$(N确保数学2)$几何相位门只需一步即可实现，并且所需时间不会随着量子比特数的增加而增加，这可以显著降低实际量子计算和量子算法的物理实现的复杂性。
A scheme is proposed for realizing geometric quantum computation with one-qubit unitary gates and $N$-qubit $(N\ensuremath{\ge}2)$ phase gates in cavity QED. In the scheme, the cavity field and excited states are virtually excited by controlling appropriately atom-field couplings and engineering adiabatic passage; thus the gate operations are insensitive to the cavity decay and the atomic spontaneous emission. Furthermore, the $N$-qubit $(N\ensuremath{\ge}2)$ geometric phase gates can be realized just by one step and the required time does not increase with the number of qubits, which can significantly reduce complexity of physical realization of practical quantum computation and quantum algorithms.
