Abstract
A hybrid quantum-classical (HQC) computer which includes both a classical computer component and a quantum computer component performs generative learning on continuous data distributions. The HQC computer is capable of being implemented using existing and near-term quantum computer components having relatively low circuit depth.
Claims61
A device comprising:
- a variational quantum generator circuit comprising:
- a first quantum encoding circuit, which receives as input a real value z from a classical distribution and encodes the real value as an input quantum state |R(z), having r qubits;
- and
- a quantum generator circuit G(Θg), which receives the input quantum state and acts on a register of n qubits including the input quantum state, with n≥r, and which generates classical data xFake by measuring, by a measurement decoding component, at least one expectation value of an output state |ψ(x) relative to a fixed set of observables.
