摘要：

A scheme based on pulse control is described for suppressing noise in quantum computation without the cost of stringent quantum computing resources. It is shown that environment-induced noise and decoherence, whether in quantum memory or in gate operations, all can be much reduced by applying a suitable sequence of bit-flipping and phase-flipping pulses.
