Abstract

Experimental realization of automated error correction is demonstrated through IBM Quantum Experience for Bell and GHZ states using a measurement based approach upon ancilla qubits. The measurement automatically activates error correcting unitary operations to restore the system to its original entangled state. We illustrate the algorithm for the maximally entangled qudit case by applying appropriate Hadamard and Controlled-NOT gates.

    • At the very least the machines are being used to experimentally verify quantum correction algorithms. See, e.g., https://arxiv.org/abs/1708.02297 and https://arxiv.org/abs/1709.01866 and https://arxiv.org/pdf/1709.00990.pdf
