Nature: Scientists achieve continuous operation of a 3000-qubit system

In a paper published on September 15 in the journal Nature, a team of researchers from Harvard University and MIT demonstrated an experimental architecture for high-speed reloading and continuous operation of large-scale atomic array systems, while enabling coherent storage and manipulation of quantum information. Using a light-capture reload rate of 300,000 atoms per second, the researchers achieved the generation of more than 30,000 initialized qubits per second, and then assembled and maintained an array containing more than 3,000 atoms for more than two hours. The scientists of this study say that this achievement lays the foundation for the development of large-scale continuous operation of fault-tolerant quantum computers.
