Microsoft Opens Maryland Quantum Lab, Granting DARPA Direct Access to Majorana 2 Hardware

Microsoft has inaugurated a 15,000-square-foot quantum research center within the University of Maryland’s Discovery District, approximately one year after the project was initially announced. The facility provides the Defense Advanced Research Projects Agency (DARPA) with physical, on-site access to Microsoft’s latest topological quantum system for independent evaluation.

Until now, DARPA and external researchers have been limited to testing Microsoft’s hardware via cloud-based remote connections. This marks the first instance where an outside agency will directly assess the company’s topological quantum hardware in a dedicated laboratory environment.

DARPA Gains Hands-On Access to Majorana 2

The installation features qubits constructed on Majorana 2, Microsoft’s second-generation topological quantum computing chip. Topological qubits are engineered to mitigate the intensive error-correction overhead typically required by other qubit architectures.

Quantum systems remain acutely susceptible to environmental interference, necessitating continuous error detection and correction during computation. Microsoft reports that Majorana 2’s material stack substitutes lead for aluminum, a change the company asserts enhances overall performance and stability.

The chip has faced skepticism from segments of the scientific community regarding earlier performance claims. Microsoft contends that granting DARPA independent access—leveraging the agency’s expertise across hardware, control systems, software, and applications—will help resolve these doubts through rigorous, third-party validation.

The company characterizes this independent scrutiny as a critical milestone in determining whether its topological approach can yield an economically viable, fault-tolerant quantum computer. The broader industry has yet to produce a broadly useful quantum machine that consistently surpasses classical systems on commercially significant workloads.

DARPA’s assessment falls under its Underexplored Systems for Utility-Scale Quantum Computing program, a component of the wider Quantum Benchmarking Initiative. This initiative aims to evaluate whether competing quantum modalities can deliver commercially useful machines by 2033.

“DARPA is an ideal partner for our work because its test and evaluation team brings expertise across the computing stack,” Microsoft stated in a blog post announcing the collaboration.

A Shared Hub for Training and Industry Collaboration

Beyond the secured DARPA testing zone, the center incorporates a hands-on quantum hardware makerspace designed for students, researchers, and professionals transitioning into the field. Seven inaugural partners have joined the effort: AMD, Intel, Bluefors, IQM, Riverlane, Quantum Motion, and Fermi National Accelerator Laboratory.

Fermilab’s participation extends to a collaboration exploring how its Quantum Instrumentation Control Kit might bolster broader quantum education initiatives. Within the makerspace, participants will assemble functional, small-scale quantum systems utilizing components sourced from leading hardware and computing firms.

Microsoft acknowledged the support of Maryland’s Capital of Quantum Initiative, spearheaded by Governor Wes Moore, which funded the renovation of the original Discovery Center building.

The facility will also serve as an integration lab for prospective partners to validate interoperability between their technologies and Microsoft’s broader quantum platform. Hardware engineers can use the space to integrate machines or components, while developers prototype potential applications.

Microsoft’s overarching strategy focuses on supporting a diverse array of quantum hardware types through a unified software and infrastructure layer.
