Atom Computing

California-based Atom Computing develops quantum computers using qubits made from neutral atoms. The company claims that its technique is potentially scalable up to more than one million qubits. 

The company is currently building its prototypes and hopes to provide cloud access to large numbers of very coherent qubits. In July 2021 , Atom introduced Phoenix, its first quantum system, which it claims has demonstrated high stability and scalability with error-correction capabilities with the ability to trap 100 atoms to control and manipulate their quantum states using optical tweezers all at once. The company also expects to debut its second-generation system in 2022.

In October 2023 , the company developed a gate-based 1,225-site atomic array with 1,180 qubits for its next-gen quantum computing platform, set to be released in 2024, following the release of its 100-qubit system in 2021.

Key customers and partnerships

In January 2023, PsiQuantum , Atom Computing, and Microsoft joined the Underexplored Systems for Utility-Scale Quantum Computing (US2QC) program initiated by the Defense Advanced Research Projects Agency (DARPA). The program, planned for five years across four phases, will focus on identifying if underexplored quantum computing approaches are able to unlock utility-scale activity sooner than current predictions. 

Funding and financials

In January 2022, Atom Computing raised USD 60 million in a Series B funding round led by Third Point Ventures. The proceeds were allocated toward building the company’s second-gen quantum computing systems to solve complex real-world practical problems and commercializing the technology.
