描述了一种基于漂浮在液氦上的电子的量子计算机。每个量子位由捕获在氦表面下方微电极上的电子的基态和第一激发态的组合组成。我们描述了准备量子位初始状态的机制、量子位的操作以及建议的读出。原则上,该系统能够在退相干时间(波函数崩溃的时间)内进行模拟104操作。
A quantum computer based on electrons floating over liquid helium is described. Each qubit is made of combinations of ground and first excited states of an electron trapped over micro-electrodes just below the helium surface. We describe mechanisms for preparing the initial state of the qubit, operations with the qubits, and a proposed readout. This system is, in principle, capable of sim 104 operations in a decoherence time, the time in which the wave function collapses.
