根据 A. Kitaev 的建议,我们探索了容错量子计算和二维空间维度中的非阿贝尔量子统计之间的联系。适当设计的自旋系统可以支持表现出长程非阿哈罗诺夫-玻姆相互作用的局部激发(准粒子)。编码在准粒子电荷中的量子信息具有很强的抗退相干性,并且可以通过将一个准粒子携带在另一个准粒子周围来可靠地处理。如果信息被编码在准粒子对中,那么阿哈罗诺夫-玻姆相互作用足以用于通用容错量子计算。
Following a suggestion of A. Kitaev, we explore the connection between fault-tolerant quantum computation and nonabelian quantum statistics in two spatial dimensions. A suitably designed spin system can support localized excitations (quasiparticles) that exhibit long-range nonabelian Aharonov-Bohm interactions. Quantum information encoded in the charges of the quasiparticles is highly resistant to decoherence, and can be reliably processed by carrying one quasiparticle around another. If information is encoded in pairs of quasiparticles, then the Aharonov-Bohm interactions can be adequate for universal fault-tolerant quantum computation.
