An algorithmic benchmark for quantum information processing

Article Abstract:

It has been possible to develop an experimental realization of an algorithmic benchmark using a nuclear magnetic resonance technique involving coherent manipulation of seven qubits. This research initially used a three-qubit example of the cat-state benchmark, and the seven-qubit version was then implemented using fully labelled trans-crotonic acid. It was established that the ability to implement the cat-state benchmark with high fidelity is a reliable indication of what sorts of tasks can be carried out in the system in question. The output of the benchmark can be used as a reliable pseudopure state for quantum algorithms using one less quibt or as the input to an n-bit error-correction benchmark.

Complete quantum teleportation using nuclear magnetic resonance

Article Abstract:

Teleportation has been implemented using liquid state nuclear magnetic resonance (NMR) on an ensemble of trichloroethylene (TCE) molecules. The projective measurement step in the standard description of teleportation is modified, while still preserving the teleportation effect. A method based on the two-part Brassard and colleagues method for implementing the Bell basis measurement was used.
