Quandoom -- DOOM as a quantum circuit (2412.12162v1)

Abstract: Since the early 2000s there has existed the meme that "DOOM can run on anything". Whether it be an ATM or a calculator, someone at some point has recompiled DOOM to run on it. Now the quantum computer finally joins the list. More specifically, this project represents the first level of DOOM loosely rewritten using Hadamards and Toffolis which, despite being a universal gate set, has been designed in such a way that it's classically simulable, able to reach 10-20 frames per second on a laptop. The circuit uses 72,376 total qubits and at least 80 million gates, thus it may have use as a benchmark for quantum simulation software.
