Real-time operator evolution in two and three dimensions via sparse Pauli dynamics
Tomislav Begušić, Garnet Kin-Lic Chan
We study real-time operator evolution using sparse Pauli dynamics, a recently developed method for simulating expectation values of quantum circuits. On the examples of energy and…
Fast and converged classical simulations of evidence for the utility of quantum computing before fault tolerance
Tomislav Begušić, Johnnie Gray, Garnet Kin-Lic Chan
A recent quantum simulation of observables of the kicked Ising model on 127 qubits implemented circuits that exceed the capabilities of exact classical simulation. We show that sev…
Simulating quantum circuit expectation values by Clifford perturbation theory
Tomislav Begušić, Kasra Hejazi, Garnet Kin-Lic Chan
The classical simulation of quantum circuits is of central importance for benchmarking near-term quantum devices. The fact that gates belonging to the Clifford group can be simulat…
