A Simple Proof of PreciseQMA = PSPACE

Quantum Physics 2022-06-22 v1 Computational Complexity

Abstract

We give an alternative proof of PreciseQMA = PSPACE, first proved by Fefferman and Lin (Innov. Theor. Comp. Sci. 2018), where PreciseQMA is the class Quantum Merlin-Arthur with inverse exponential completeness-soundness gap. We adapt the proof of Quantum Cook-Levin Theorem to prove the inclusion PSPACE in PreciseQMA.
