Quantum computing relies on the manipulation of millions of information units called qubits, yet these qubits are difficult to assemble. Further, monolithic superconducting quantum systems are limited in size and fidelity, which predicts scientists\u2019 rate of success in performing logical operations.\u00a0<\/p>\n
The solution developed? Finding modular ways to construct quantum computers. <\/p>\n
Much like plastic children\u2019s bricks that lock together to create larger, more intricate structures, scientists can build<\/a> smaller, higher quality modules and string them together to form a comprehensive system.<\/p>\n Connecting up to make big<\/p>\n In trials, this approach to scalable quantum computing was performed by demonstrating a viable and high-performance modular architecture for superconducting quantum processors. The approach expands on previous modular designs and potentially paves the way toward scalable, fault-tolerant and reconfigurable quantum computing systems.<\/p>\n By constructing a system where two devices are connected with superconducting coaxial cables to link qubits across modules, the research team demonstrated ~99% SWAP gate fidelity, representing less than 1% loss. This ability to connect and reconfigure separate devices with a cable while retaining high quality provides novel insight to the field in designing communication protocols.<\/p>\n![\"Designers](\"https:\/\/www.newsbeep.com\/au\/wp-content\/uploads\/2025\/09\/798f6fe68f7e9dab43a7dab6e83278129b5365d0.jpg\")
