이해하기 어려운 양자컴퓨터 원리
In order to make a quantum computer work, the following two things are required: first, the phase of the wavefunction must be preserved between computing elements. That means that the computing elements are in an entangled state, acting together as a coherent quantum system. Second, the set of computing elements, working together, must be isolated from their environment to avoid "decoherence", t..
