Quantum Memristors with Quantum Computers
The encoding of memristive quantum dynamics on a digital quantum computer using a set of auxiliary qubits is proposed, and this method is extended to the case of two coupled quantum memristors, opening the door to the study of neuromorphic quantum computing in the NISQ era.
Abstract
We propose the encoding of memristive quantum dynamics on a digital quantum computer. Using a set of auxiliary qubits, we simulate an effective non-Markovian environment inspired by a collisional model, reproducing memristive features between expectation values of different operators in a single qubit. We numerically test our proposal in an IBM quantum simulator with 32 qubits, obtaining the pinched hysteresis curve that is characteristic of a quantum memristor. Furthermore, we extend our method to the case of two coupled quantum memristors, opening the door to the study of neuromorphic quantum computing in the NISQ era.
