Universal Fault-Tolerant Quantum Computation in the Presence of Spontaneous Emission and Collective Dephasing
Kaveh Khodjasteh, Daniel A. Lidar · Physical Review Letters · 2002
A universal and fault-tolerant scheme for quantum computation is proposed which utilizes a class of error correcting codes that is based on the detection of spontaneous emission (of, e.g., photons, phonons, and ripplons). The scheme is compatible with a number of promising solid-state and quantum-optical proposals for quantum computer implementations, such as quantum dots in cavities, electrons on helium, and trapped ions.
