講演概要
One of the most promising application areas for quantum computing is the simulation of quantum-mechanical systems. Full many-particle simulations are generally intractable using classical computing because the full representation of any quantum-mechanical system requires a Hilbert space whose dimension increases exponentially with the system size. By contrast, representing the same system on a quantum register only requires a number of qubits that increases linearly with the system size.
In this seminar lecture, I will share some methods and techniques that we have developed to allow us to make the most of the limited quantum computing resources currently available. Reducing resource requirements has allowed us to calculate the many-particle ground-state energy of molecular fluorine, a molecule that has three times more electrons and twice as many valence orbitals as beryllium hydride, the previously largest molecule computed at the same level of theory using a quantum computer.
