Quantum annealing with error mitigation

Understand

Quantum annealing (QA) is one of the efficient methods to calculate the ground-state energy of a problem Hamiltonian.

• In the absence of noise, QA can accurately estimate the ground-state energy if the adiabatic condition is satisfied.
• However, in actual physical implementation, systems suffer from decoherence.
• On the other hand, much effort has been paid into the noisy intermediate-scale quantum (NISQ) computation research.
