Harvard scientists have succeeded in developing a quantum machine featuring over 3,000 quantum bits (qubits), which can operate continuously for more than two hours without requiring a restart. This innovation represents a significant advancement in quantum computing technology and aims to overcome the critical issue of “atom loss,” where qubits escape and lose information. The research team, which includes members from MIT, utilized a system with “optical lattice conveyor belts” and “optical tweezers,” allowing them to rapidly resupply qubits and maintain processing power. This groundbreaking work not only demonstrates large-scale continuous operation but also has implications for performing computations. The researchers believe that they are now closer to realizing practical quantum computers capable of executing billions of operations over extended periods. In addition to this study, the team has introduced methods for reconfigurable atom arrays and improved error correction, further contributing to the evolving field of quantum computing. The research received funding from several federal agencies, including the U.S. Department of Energy and the National Science Foundation.
