About
QuEra Computing develops neutral atom quantum computers based on research from Harvard, led by Mikhail Lukin, and MIT, with Vladan Vuletic and Markus Greiner. As of March 2026 it is the world leader in verified logical qubit count. In January 2026, QuEra published in Nature (doi:10.1038/s41586-025-09848-5) a result of 96 logical qubits from 448 physical atoms using high-rate [[16,6,4]] codes, achieving below-threshold error suppression, a critical milestone for fault-tolerant quantum computing. The company currently operates 37 logical qubits at AIST Japan and has demonstrated continuous 2-hour operation with 3,000 physical qubits. It is targeting 100 logical qubits with 10,000 physical qubits in 2026 to 2027. QuEra raised $230M in 2025, led by Google Quantum AI and SoftBank Vision Fund 2, following a prior $47M round in October 2024, bringing total funding above $507M. Investors also include NVentures. QuEra was selected for DARPA QBI Stage B in November 2025 and partners with the Massachusetts Green High Performance Computing Center. In February 2026 it announced a $4M partnership with Roadrunner Venture Studios for a quantum testbed in Albuquerque, New Mexico. QuEra demonstrated the first logical magic state distillation and achieved transversal algorithmic fault tolerance with Harvard and Yale, enabling algorithm execution 10 to 100 times faster. In March 2026 it integrated with NVIDIA's NVQLink architecture for higher logical cycle speed and QEC throughput. The company open-sourced Tsim, a GPU-accelerated neutral-atom simulator that supports circuits of more than 80 physical qubits with millions of samples in parallel on NVIDIA GH200 hardware, demonstrating 85-qubit simulation in about 600ns. Tsim is available on GitHub and integrated with the Bloqade.jl ecosystem. In March 2026, Mikhail D. Lukin, the Harvard professor and QuEra co-founder, was awarded the Bell Prize alongside Antoine Browaeys and Mark Saffman for neutral atom quantum computing research. I
