Atom Computing - Quantum Computing Company Profile | Quantum Navigator

Atom Computing

In 2024-2025, Atom Computing became the first company to cross the 1,000-qubit threshold for a universal gate-based quantum system, creating a 1,225-site atomic array populated with 1,180 qubits in its next-generation neutral atom quantum computing platform. Atom Computing was recognized by Fast Company as one of the world’s most innovative companies in 2025 for its advancements in neutral atom quantum computing. In a major milestone, Microsoft and Atom Computing achieved record-breaking quantum entanglement by creating and entangling 24 logical qubits on a commercial quantum machine, and also used 28 logical qubits to perform successful computations based on the Bernstein-Vazirani algorithm, producing more accurate solutions than the corresponding computation based on physical qubits. These achievements demonstrate Atom Computing’s leadership in neutral atom technology and logical qubit operations.

Harvard University - Quantum Computing Company Profile | Quantum Navigator

Harvard University

Harvard University is a private Ivy League research university founded 1636 in Cambridge Massachusetts. Central to Harvard quantum initiatives is Harvard Quantum Initiative uniting researchers from various disciplines to advance quantum science and engineering. In September 2025, a team of Harvard physicists led by Mikhail Lukin (Joshua and Beth Friedman University Professor) achieved a historic breakthrough by building the first quantum computer that can operate continuously for over 2 hours without restarting, published in Nature. The system operates an array of more than 3,000 qubits (neutral atoms) and theoretically could continue indefinitely, representing a massive improvement over existing quantum computers that typically run for milliseconds or at most 13 seconds. The breakthrough was achieved by replenishing qubits in real time, injecting new atoms at a rate of 300,000 per second using an optical lattice conveyor belt system to counteract atom loss and maintain quantum information, with over 50 million atoms cycled through the system during the two-hour demonstration. This transformative achievement demonstrates that quantum computers capable of running forever in practice are now just three years away (down from five+ years previously), marking a critical milestone toward practical, continuously operating quantum computing systems. Harvard Quantum Initiative is one of strongest in country heavily focused on quantum networking quantum chemistry and quantum materials research. Harvard conducts quantum research spanning quantum processors quantum algorithms quantum communication networks quantum simulation and quantum sensing. The university maintains partnerships with leading quantum companies including QuEra Computing and government agencies. Harvard serves quantum research community through fundamental quantum research quantum education programs and technology transfer advancing quantum information science and quantum technology commercialization supporting USA quantum leadership.
