Adiabatic quantum imaginary time evolution
Kasra Hejazi, Mario Motta, Garnet Kin-Lic Chan
We introduce an adiabatic state preparation protocol which implements quantum imaginary time evolution under the Hamiltonian of the system. Unlike the original quantum imaginary ti…
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…
Symmetry protected entanglement in random mixed states
Kasra Hejazi, Hassan Shapourian
Symmetry is an important property of quantum mechanical systems which may dramatically influence their behavior in and out of equilibrium. In this paper, we study the effect of sym…
No-faster-than-light-signaling implies linear evolutions. A re-derivation
Angelo Bassi, Kasra Hejazi
There is a growing interest, both from the theoretical as well as experimental side, to test the validity of the quantum superposition principle, and of theories which explicitly v…
