Title

Use of Weak Value Amplification in Quantum Computing

Abstract

We investigate a new branch of quantum computing that uses an ancillary qubit register to lessen the time complexity of the algorithm being performed. We do this through the use of pre, and post-selection on the ancillary register. Then, after the primary register and the ancillary register have gone through a specific interaction gate, we use the weak value obtained from the pre and post-selection to amplify the probability of measuring the correct result on the primary register. Though this process uses twice the number of qubits, the time complexity is shown to be drastically reduced.
