Quandoom -- DOOM as a quantum circuit

TL;DR

This paper presents a quantum circuit implementation of DOOM using Hadamards and Toffolis, serving as a potential benchmark for quantum simulation with 72,376 qubits and 80 million gates.

Contribution

It introduces the first quantum circuit version of DOOM, designed to be classically simulable and scalable for benchmarking quantum software.

Findings

Achieved 10-20 frames per second simulation on a laptop.

Constructed a circuit with 72,376 qubits and at least 80 million gates.

Demonstrated potential as a quantum simulation benchmark.

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.
