Practical Quantum Advantage in Materials Simulation

Using an IBM quantum computer and a specially designed compiler and error-suppression toolchain, we ran an algorithm using 120 qubits and over 10,000 two-qubit quantum-logic operations, simulating a Fermionic system with up to 60 interacting electrons. These simulations are beyond the reach of exact state vector simulations and achieved practical quantum advantage with a factor of 3,000 quantum improvement in time to solution when compared to state-of-the-art classical methods.
