我们提出了一种新的量子计算机的物理实现。量子比特是超冷双原子分子的电偶极矩，沿着或反对外部电场定向。单个分子被保存在一维陷阱阵列中，具有电场梯度，允许对每个位置进行光谱寻址。比特通过电偶极-偶极相互作用耦合。使用与已经演示的技术类似的技术，这种设计似乎可以导致一台大于或等于10(4)个量子比特的量子计算机，它可以在类似于S的预期退相干时间内执行类似于10(5)个CNOT门的性能。
We propose a novel physical realization of a quantum computer. The qubits are electric dipole moments of ultracold diatomic molecules, oriented along or against an external electric field. Individual molecules are held in a 1D trap array, with an electric field gradient allowing spectroscopic addressing of each site. Bits are coupled via the electric dipole-dipole interaction. Using technologies similar to those already demonstrated, this design can plausibly lead to a quantum computer with greater than or equal to10(4) qubits, which can perform similar to10(5) CNOT gates in the anticipated decoherence time of similar to5 s.
