A quantum algorithm simulates networks of classical oscillators

Mar 23, 2023

Ryan Babbush and colleagues give a quantum algorithm for selected properties of large, sparsely connected networks of classical oscillators. Its efficiency requires fast access to masses and couplings and efficient preparation of the initial quantum state.

Why it matters

The work extends quantum simulation to classical dynamics, with advantages for specific outputs and access assumptions rather than a full readout of every oscillator.
