Exponential quantum speedup in simulating coupled classical oscillators
Ryan Babbush, Dominic W. Berry, Robin Kothari +2
We present a quantum algorithm for simulating the classical dynamics of coupled oscillators (e.g., masses coupled by springs). Our approach leverages a mapping between…

Query-optimal estimation of unitary channels in diamond distance
Jeongwan Haah, Robin Kothari, Ryan O'Donnell +1
We consider process tomography for unitary quantum channels. Given access to an unknown unitary channel acting on a -dimensional qudit, we aim to output a classical des…
