Prototype quantum computers are beginning to surpass the computational abilities of classical computers. To achieve a true quantum advantage, these few-qubit prototypes will need to be scaled to hundreds of qubits, which will be tricky with the current laboratory-filling hardware. In a step toward accessible and scalable technology, Ivan Pogorelov at the University of Innsbruck, Austria, and colleagues have fabricated a compact quantum computing processor that fits inside two industry-standard server racks, which each have volumes of 1.7" m3 [1]. The processor performs on par with similar laboratory-scale versions, and it could eventually lead to an up-to-50-qubit device that could be operated by trained nonspecialists.
