Abstract
Official abstract text for this publication.
According to one embodiment, a decoding apparatus includes first and second acquisition units, a holding unit, a calculation unit, and a decision unit. The first acquisition unit acquires first measurement values of measurements performed to measure an eigenvalue of an encoded Z operator to a first encoded qubit of the two encoded qubits. The second acquisition unit acquires second measurement values of measurements performed to measure an eigenvalue of an encoded X operator to a second encoded qubit of the two encoded qubits. The holding unit holds error probabilities for the first measurement values and the second measurement values. The calculation unit calculates probabilities for measurement values of an encoded Bell measurement by using the first measurement values, the second measurement values, and the error probabilities. The decision unit decides measurement values of the encoded Bell measurement, based on the calculated probabilities.
First claim
Opening claim text (preview).
What is claimed is: 1. A decoding apparatus for use in encoded Bell measurement for two encoded qubits, comprising: a first acquisition unit configured to acquire first measurement values of measurements performed to measure an eigenvalue of an encoded Z operator with respect to a first encoded qubit of the two encoded qubits; a second acquisition unit configured to acquire second measurement values of measurements performed to measure an eigenvalue of an encoded X operator with…
