Abstract
This paper demonstrates long-time, high-fidelity quantum simulations on current hardware by simulating an XY-model spin chain on Rigetti and IBM quantum computers. The simulations utilize a new algorithm called fixed state Variational Fast Forwarding (fsVFF), which significantly reduces resource requirements compared to existing methods like the iterated Trotter method, achieving fidelity over 0.9 for 150 times longer.
