Fault Tolerant Quantum Computation with a New Reversible Gate
Fault tolerance plays a major role in quantum computer design. As the quantum environment is not stable enough when the information is read from it, better designs with error correcting capability have to be designed to overcome the information loss due to decoherence in quantum circuits. This paper presents one such fault tolerant design using a new reversible gate.
متن کاملSemi-Clifford and Generalized Semi-Clifford Operations
Fault-tolerant quantum computation is a basic problem in quantum computation, and teleportation is one of the main techniques in this theory. Using teleportation on stabilizer codes, the most well-known quantum codes, Pauli gates and Clifford operators can be applied fault-tolerantly. Indeed, this technique can be generalized for an extended set of gates, the so called Ck hierarchy gates, intro...
متن کاملFault-Tolerant Quantum Computation
It has recently been realized that use of the properties of quantum mechanics might speed up certain computations dramatically. Interest in quantum computation has since been growing. One of the main difficulties in realizing quantum computation is that decoherence tends to destroy the information in a superposition of states in a quantum computer, making long computations impossible. A further...
متن کاملFault-tolerant Quantum Computation
The discovery of quantum error correction has greatly improved the long-term prospects for quantum computing technology. Encoded quantum information can be protected from errors that arise due to uncontrolled interactions with the environment, or due to imperfect implementations of quantum logical operations. Recovery from errors can work effectively even if occasional mistakes occur during the...
متن کاملFault-tolerant holonomic quantum computation.
We explain how to combine holonomic quantum computation (HQC) with fault-tolerant quantum error correction. This establishes the scalability of HQC, putting it on equal footing with other models of computation, while retaining the inherent robustness the method derives from its geometric nature.
