Realization of Logically Labeled Effective Pure States for Bulk Quantum Computation

Realization of Logically Labeled Effective Pure States for Bulk Quantum Computation

We report the first use of ``logical labeling'' to perform a quantum computation with a room-temperature bulk system. This method entails the selection of a subsystem that behaves as if it were at zero temperature---except for a decrease in signal strength---conditioned upon the state of the remaining system. No averaging …
