quantum variational algorithm

Setting the bar for variational quantum algorithms using high-performance classical simulations

In the recently published Nature Physics research paper, we, along with our colleague Dr. David Gosset, associate professor at the University of Waterloo's Institute of Quantum Computing, show that certain properties of shallow quantum circuits on a two-dimensional grid of qubits can be simulated classically in time that grows only linearly with the number of qubits.
