Quantum Discriminator for Binary Classification. (arXiv:2009.01235v2 [quant-ph] UPDATED)

Quantum computers have the unique ability to operate relatively quickly in
high-dimensional spaces -- this is sought to give them a competitive advantage
over classical computers. In this work, we propose a novel quantum machine
learning model called the Quantum Discriminator, which leverages the ability of
quantum computers to operate in the high-dimensional spaces. The quantum
discriminator is trained using a quantum-classical hybrid algorithm in O(N
logN) time, and inferencing is performed on a universal quantum computer in
linear time. …
