Using quantum computers to simulate molecules and solids — •Michael Marthaler — HQS Quantum Simulations

Quantum computers offer tantalizing possibilities, but are currently strongly limited by their intrinsic sensitivity to errors. We discuss the prospects of using a near term processor containing 50 to 100 qubits to perform ab-initio simulations of materials. At present, the overhead for quantum error correction is so large that it cannot be implemented for near term quantum computers. This means applications have to be planned with the limitations imposed by errors in mind. Material simulations seam to be the most promising near term applications. We discuss how simulations would be performed on quantum computers and how this relates to existing methods in quantum chemistry.
