Modelling and Simulating the Noisy Behaviour of Near-term Quantum Computers

Understand

Noise dominates every aspect of near-term quantum computers, rendering it exceedingly difficult to carry out even small computations.

• In this paper we are concerned with the modelling of noise in Noisy Intermediate-Scale Quantum (NISQ) computers.
• We focus on three error groups that represent the main sources of noise during a computation and present quantum channels that model each source.
• We engineer a noise model that combines all three noise channels and simulates the evolution of the quantum computer using its calibrated error rates.
