# QuEra Computing
**[[https://www.quera.com|QuEra Computing]]** spun out of research at Harvard and MIT. Like [[atom-computing]], it builds on [[neutral-atom-qubits]]: rubidium atoms in optical tweezer arrays, with Rydberg-state excitation driving two-qubit gates. Its particular focus is reconfigurable geometry, since tweezers can be rearranged between circuit layers to match whatever connectivity an algorithm needs.

QuEra also runs its atom arrays in an analog mode, directly programming atom interactions to simulate physical systems like frustrated magnets. Its systems are available through Amazon Braket alongside its own cloud offering.
