Abstract

Quantum computer could solve classically intractable problems. While since realizing a universal quantum computer is challenging with current technology, a more practical question before having a fully-fledged quantum computer is what we can do with current and near-term quantum hardware. Focusing on the noisy-intermediate-scaled-quantum regime, we introduce variational quantum algorithms for solving static and dynamic problems of many-body physics. Considering the limitations on the qubits number and circuit depth, we introduce the hybrid tensor network and perturbative quantum simulation methods that allow us to solve practical large problems. With the rapid development of quantum hardware, variational quantum algorithms may finally enable genuine quantum advantage demonstration in the noisy-intermediate-scaled quantum era.
