利用极性分子进行稳健量子计算的方案

Schemes for robust quantum computation with polar molecules

S. F. Yelin, K. Kirby, R. Cote

摘要:

我们建议使用一种新的平台-超冷极性分子-用于具有可切换相互作用的量子计算。通/断开关是通过选择性地将“0”或“1”量子比特之一--长寿命的分子状态--激发到具有显著不同的偶极矩的“激发”分子状态来实现的。我们描述了各种方案的基础上,通过光学,微波,或电场的选择性激发基态和激发态之间的偶极相互作用的切换。我们还推广的计划,以利用偶极封锁机制时,偶极相互作用非常强。这些方案可以在最近提出的几种架构中实现。

英文摘要:

We propose to use a new platform - ultracold polar molecules - for quantum computing with switchable interactions. The on/off switch is accomplished by selective excitation of one of the "0" or "1" qubits - long-lived molecular states - to an "excited" molecular state with a considerably different dipole moment. We describe various schemes based on this switching of dipolar interactions where the selective excitation between ground and excited states is accomplished via optical, micro-wave, or electric fields. We also generalize the schemes to take advantage of the dipole blockade mechanism when dipolar interactions are very strong. These schemes can be realized in several recently proposed architectures.
