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.

www.nature.com A cryogenic on-chip microwave pulse generator for large-scale superconducting quantum computing - Nature CommunicationsIntegrating a control interface with a quantum processor as the number of qubits scales is a significant challenge. Here the authors report a cryogenic on-chip microwave pulse generator for superconducting qubits with high degree of controllability, negligible heat load, and a small footprint.

Multiphoton interference is at the heart of photonic quantum technologies. Arrays of integrated cavities can support bright sources of single photons with high purity and small footprint, but the inevitable spectral distinguishability between photons generated from nonidentical cavities is an obstac...

phys.org Elegant use of noise for quantum computingScientists around the world work hard to rinse quantum systems for noise, which may disturb the function of tomorrow's powerful quantum computers. Researchers from the Niels Bohr Institute (NBI) have found a way to use noise to process quantum information. This raises the performance of the quantum ...
