June 2020 : Quantum simulations of materials on near-term quantum computers

The paper entitled "Quantum simulations of materials on near-term quantum computers" has been accepted on npj Computational Materials. We wrapped up calculations performed on a quantum computer and showed that they yield results in agreement with those obtained with exact diagonalization on classical architectures, paving the way to simulations of realistic materials on near-term quantum computers. Our hybrid classical-quantum method is based on a quantum embedding theory for the calculation of strongly-correlated electronic states of active regions, with the rest of the system described within density functional theory. We demonstrate the accuracy and effectiveness of the approach by investigating several defect quantum bits in semiconductors that are of great interest for quantum information technologies.
