Quantum logic gate constructions with one-bit "teleportation"
Xinlan Zhou, Debbie Leung, Chuang, I L · CERN Document Server (European Organization for Nuclear Research) · 2000
We present a general method to construct quantum logic gates using one-bit``teleportation'' as a basic primitive, extending previous results based ontraditional two-bit teleportation (D. Gottesman and I. L. Chuang, Nature {\\bf402}, 390, 1999). This allows the realization of a variety of useful quantumoperations that cannot be directly performed due to some physical constraints.In particular, this technique leads to straightforward and systematicconstruction of many fault-tolerant encoded operations, including the $\\pi/8$and Toffoli gates, and remote quantum operations.
