Schrodinger Cat Experiments on quantum computation at Los Alamos

Los Alamos is a leader in Experimental Quantum Computation. The recent discovery that it was possible to use Nuclear Magnetic Resonance (NMR) for quantum computation has made experimental work leap forward. The 3-qubit quantum computer using NMR techniques with the molecule trichloroethylene is the state of the art at present (winter 1998).



  • Quantum Computation using NMR

    We have succeeded at creating a GHZ state. This is the "big brother" of an Einstein-Podolsky-Rosen (EPR) state. Using qubits with state |0> and |1>, we have created the state |000>+|111>. It is well known form the foundations of quantum mechanics. Both the EPR and the GHZ state have properties which are non-classical. For more details see our paper NMR-GHZ

    We have also been the first to demonstrate quantum error correction. This work is a collaboration with Tim Havel from Harvard and David Cory form MIT. See our paper Experimental Quantum Error Correction or pdf version
