摘要
在P.W.Shor的工作基础上,提出存放K个量子位的任意态时,使用6K个量子位进行编码,并且用电磁波脉冲实现正变换。
One of the main difficulties of quantum computation is that decoherence destroys the information in a quantum computer.On the basis of P.W.Shor's work,we propose a way of storing an arbitrary state of K qubits by using 6K qubits encoded and performing unitary transformation by electromagnetic wave tipping pulses,so that we go a step further reducing the effects of decoherence in quantum memory.
