Quantum computers hold the promise to revolutionize modeling and calculations. By employing the peculiar laws of quantum mechanics, they can perform calculations that would take even the fastest supercomputers billions of years to complete. Building and operating quantum computers has many challenges, and while these devices are still a long way off, some components are already breaking records. ADVERTISEMENT For a few years now, different organizations and private companies have been announcing "Quantum supremacy", the ability for a quantum processor to do a calculation faster than a regular supercomputer would. The latest claimant to this record is the Zuchongzhi-3, a...
