The paper by Daniel Gottesman and Isaac L. Chuang presents a method to create various quantum gates using quantum teleportation, which can be applied to construct a quantum computer based on single qubit operations, Bell measurements, and GHZ states. The authors demonstrate how quantum teleportation can be used to perform a controlled-NOT (cNOT) gate between two qubits deterministically. They also show that this technique can be extended to create fault-tolerant quantum gates, particularly those in the Clifford group, which are crucial for quantum error correction and fault-tolerant computation. The construction of these gates involves preparing specific entangled states, such as GHZ states, and performing Bell basis measurements. The paper highlights the potential of using quantum teleportation to simplify and generalize the preparation of fault-tolerant gates, making quantum computing more feasible with current experimental capabilities.The paper by Daniel Gottesman and Isaac L.
