我们讨论了利用具有库珀凝聚态的超导体在三重态对中(其中凝聚态对的自旋为S=1)实现量子计算机的可能性。具有三重态成对凝聚的超导体具有通常的(单态成对，S=0)超导体所没有的独特特征。某些三重态超导体(如Ruthenate)中序参数的对称性对应于双简并手征态。这些态可以作为量子计算的量子比特基态。
We discuss possibilities of utilizing superconductors with Cooper condensates in triplet pairing states (where the spin of condensate pairs is S=1) for practical realization of quantum computers. Superconductors with triplet pairing condensates have features that are unique and cannot be found in the usual (singlet pairing, S=0) superconductors. The symmetry of the order parameter in some triplet superconductors (e.g., ruthenates) corresponds to doubly-degenerate chiral states. These states can serve as qubit base states for quantum computing.
