Preparing Projected Entangled Pair States on a Quantum Computer
Preparing Projected Entangled Pair States on a Quantum Computer
We present a quantum algorithm to prepare injective PEPS on a quantum computer, a class of open tensor networks representing quantum states. The run-time of our algorithm scales polynomially with the inverse of the minimum condition number of the PEPS projectors and, essentially, with the inverse of the spectral gap …
