QuEra Computing Inc. is a quantum computing company based in Boston, Massachusetts. The company develops quantum computers using neutral atoms based on research conducted at both Harvard University and MIT. QuEra also develops software for simulating systems of Rydberg atoms. and finding solutions to combinatorial optimization problems.
QuEra actively conducts research in Condensed Matter Physics and combinatorial optimization using neutral atoms as well.
QuEra Computing was founded by Mikhail Lukin, Vladan VuletiÃÂ, Markus Greiner, Dirk Englund, Nathan Gemelke, and John Pena in 2018.
Prior to QuEra's founding, research into using and controlling neutral atoms had already started in 2015 at Harvard and MIT, culminating in a 51-qubit machine which later led to the development of a 256-qubit machine.
On October 24, 2024, the Massachusetts Green High Performance Computing Center announced a $16 million expansion to its computing campus, planning to build a quantum computing complex. QuEra Computing was announced as a partner in the project.
On June 3, 2025, QuEra opened a 3,500 sq. ft. flagship UK hub in Harwell Science and Innovation Campusâ Tech Foundry. This builds upon QuEraâÂÂs existing collaboration with the National Quantum Computing Centre (NQCC) and supports the companyâÂÂs expansion through the UK and across Europe.
On February 4, 2026, the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Lab (Berkeley Lab) called for proposals as part of its Quantum Computing Access at NERSC (QCAN) program to conduct research on QuEraâÂÂs Aquila and Gemini. Up to six projects will be selected for the three-month Stage A, to commence in April 2026 to demonstrate the potential to run on real hardware. Aquila teams will be allocated up to 12.5 hours of QPU usage each while Gemini teams will focus on simulation and workflow development instead of hardware usage. Aquila teams that advance to Stage B will be allocated up to 25 hours of additional QPU time each to complete their research, while Gemini teams will be allocated up to 10 hours of QPU time each. If any teams do not advance, their QPU time will be redistributed to advancing teams. Projects will be completed by December 31, 2026.
QuEra uses neutral atoms based on Rubidium which are controlled and trapped using lasers as its qubits. The company commercializes a neutral atom array developed in Mikhail LukinâÂÂs lab through a licensing agreement with HarvardâÂÂs Office of Technology Development for the Lukin groupâÂÂs patent portfolio. Ultra-cold, suspended rubidium atoms move about and can be entangled mid-computation to perform gates. Logical operations involve the parallel, multiplexed, laser control of the entire groups of atoms that constitute logical qubits.
On November 1, 2022, QuEra released its 256-qubit machine Aquila, to the general public through the Amazon cloud service Braket.
On January 9, 2024, QuEra published a three-year roadmap. It showed >256 atoms with 10 logical qubits and transversal gates in 2024, >3,000 atoms with 30 logical qubits and magic state distillation in 2025, and >10,000 atoms with 100 logical qubits in 2026. The logical qubits were defined as having lower error rates than their constituent physical qubits. A cloud-based logical qubit simulator was due in the first half of 2024.
QuEra currently supports an analog computing mode that relies on the Rydberg blockade phenomena and the position of atoms to achieve superposition and entanglement. The analog mode could allow problems such as the Maximum Weight Independent set (graph theory) (MWIS) to be expressed and solved with research from the company to map other problems onto MWIS as well
QuEra planned to offer a hybrid analog-digital quantum computer followed by a fully digital gate-based system. The analog Aquila is typically capable of three shots per second, while the digital Gemini is typically capable of one shot per second.
QuEra was selected by the Defense Advanced Research Projects Agency (DARPA) to participate in Stage B of the Quantum Benchmarking Initiative (QBI), joining ten other leading companies in the quantum computing industry. This selection follows QuEra's successful completion of Stage A, which required participants to outline a path to developing utility-scale quantum computers. The QBI program seeks to assess whether a practical, industrially useful quantum computer can be realized by 2033.
Aquila is a programmable quantum simulator that uses highly focused lasers to trap and precisely arrange individual ultracold rubidium atoms into two-dimensional arrays of up to 256 qubits. A spatial light modulator shapes an optical two-dimensional wavefront, which transforms light into optical tweezers. A first set of optical tweezers loads atoms into a random arrangement, then a second set moves them into a defect-free antiferromagnetic arrangement in which each atom has the opposite magnetic moment of its neighbors, and then coherent optical beams are used to excite the atoms into Rydberg states. Atomic interactions are used to perform Analog Hamiltonian Simulation (AHS).
Gemini is a 260-atom gate-model quantum computer using 87Rubidium with a dynamic qubit array (DQAâ¢) that allows parallel operations and all-to-all connectivity with room temperature operation. There is a storage zone and an entanglement zone for gate operations. Single-qubit gate fidelity is >99.9% fidelity, two-qubit gate fidelity is >99.2%, and SPAM fidelity is 99.7%. The shot rate is one per second. âÂÂGeminiâ has been used to demonstrate magic state distillation and is designed for hybrid computing with high-performance computing (HPC) and analog systems.

A series of two optical lattice conveyor belts transport atom reservoirs into the science region, where atoms in spin-polarized or coherent superposition states are extracted into optical tweezers at a reloading rate of 300,000 atoms per second. The 30,000+ initialized qubits per second are used to assemble and maintain a 3,000+ atomic array for more than 2âÂÂhours. Nearby stored qubits are unaffected.
