Vari-Cool: a non-unitary quantum variational protocol for simulated cooling
Jeffrey Z. Song, Gilad Kishony, Erez Berg +1
We introduce a variational approach for preparing low energy states of arbitrary target Hamiltonians. The protocol is defined in terms of a repeated cycle consisting of p layers of…
