Abstract
Advancements in quantum computing are evolving from initial stages to practical uses in fields like chemical and biomedical sciences. Yet, the noisy intermediate-scale phase of quantum computing presents hurdles due to scarce quantum resources, limiting progress in these vital sectors. To navigate these challenges, it's essential to simulate quantum computing on traditional computers, aiding in quantum algorithm development and hardware validation. However, current simulators often face memory constraints, especially with extensive quantum chemistry tasks. Addressing this, we present a groundbreaking solution: a high-speed, parallel variational quantum eigensolver (VQE) simulator. By utilizing matrix product states and embedding theory, this simulator offers a sturdy foundation for large-scale quantum chemistry simulations. To highlight its prowess, we applied it to study ethane's torsional barrier and measure protein-ligand interactions, demonstrating its adaptability. Notably, our simulation reaches up to 1000 qubits, delivering a remarkable speed of 216.9 PFLOP/s. Achieved on a state-of-the-art Sunway supercomputer, this sets a new benchmark for quantum chemistry emulation in quantum computing.
