我们提出了一种直接实现原子囚禁在高Q值光学腔中的$N$量子位控制相位门的一步方案，而不需要求助于一系列单量子位和两量子位门。实现该方案所需的相互作用时间不会随着量子比特数的增加而增加。这可能会导致更有效地构建量子电路和量子算法。
We present a one-step scheme for direct implementation of an $N$-qubit controlled-phase gate with atoms trapped in a high-$Q$ optical cavity without resorting to a sequence of single- and two-qubit gates. The interaction time that is required to implement the scheme does not rise with increasing number of qubits. This might lead to more efficient construction of quantum circuits and quantum algorithms.
