  • Title: Spin based heat engine: demonstration of multiple rounds of algorithmic cooling.
    Author: Ryan CA, Moussa O, Baugh J, Laflamme R.
    Journal: Phys Rev Lett; 2008 Apr 11; 100(14):140501. PubMed ID: 18518015.
    Abstract:
    We experimentally demonstrate multiple rounds of heat-bath algorithmic cooling in a 3 qubit solid-state nuclear magnetic resonance quantum information processor. By pumping entropy into a heat bath, we are able to surpass the closed system limit of the Shannon bound and purify a single qubit to 1.69 times the heat-bath polarization. The algorithm combines both high fidelity coherent control and a deliberate interaction with the environment. Given this level of quantum control in systems with larger reset polarizations, nearly pure qubits should be achievable.
