Atom Computing raises $300M for neutral-atom quantum computer

Atom Computing raised $300 million to build fault-tolerant quantum computers using neutral atoms with nuclear-spin qubits. The funding includes $100 million from Third Point Ventures, DCVC, Cisco Investments and a $100 million U.S. Department of Commerce grant. The company's neutral-atom approach uses qubits with equal electrons and protons to stabilize sensitive quantum states against environmental noise.
