Loss-tolerant optical qubits

Phys Rev Lett. 2005 Sep 2;95(10):100501. doi: 10.1103/PhysRevLett.95.100501. Epub 2005 Aug 30.


We present a linear optics quantum computation scheme that employs a new encoding approach that incrementally adds qubits and is tolerant to photon loss errors. The scheme employs a circuit model but uses techniques from cluster-state computation and achieves comparable resource usage. To illustrate our techniques we describe a quantum memory which is fault tolerant to photon loss.
