Full speed ahead. America’s largest quantum computing project continues to take shape at the Illinois Quantum and Microelectronics Park on Chicago’s South Side, where the shell of PsiQuantum’s first building—spanning over 65,000 square feet—is now complete.

This is our quantum memory under construction: a rack of steel and about a hundred optical fibres (100km of total length). When fully populated, we'll store 1000s of photonic qubits in each of these. These memories, built from ultra-stable optical fibre and ultra-low-loss large optical switches, reduce the overall footprint of our useful quantum computer by 1000x.

Quantum computing advances when more people can build, experiment, and discover.​ With PsiQuantum Construct now open-access, researchers and developers have free tools to design and explore quantum algorithms.​ We’re excited to see what you build: bit.ly/4o40RPK

This week marks an exciting milestone for PsiQuantum in Australia with the official opening of our Test & Validation Lab at Griffith University’s Nathan Campus in Brisbane South. The facility features “Poseidon,” one of Australia’s most powerful custom cryogenic systems, enabling our teams to cool, test, and measure photonic quantum chips at scale as we progress toward utility-scale, fault-tolerant quantum computing. We are proud to partner with @Griffith_Uni and continue growing Queensland’s world-class quantum ecosystem alongside leading researchers, students, and industry partners. Thanks to all our partners and supporters who turned out to support the official opening.

Construct, our software suite of quantum algorithm tools, is now available via open-access. As quantum hardware continues to scale, it's critical that algorithm and applications teams have access to comprehensive software tools built for fault-tolerant quantum computing (FTQC). Since Construct was launched, feedback from early users made one thing especially clear: These tools need to get into more hands. Construct is now free and available to everyone. The software suite includes a visual circuit design tool, Python libraries, a resource analyzer, and more. Everything you need to design, develop, and optimize FTQC algorithms. bit.ly/4dHlRqU

NEW: Inside @PsiQuantum's Silicon Photonic Chipset *Never-Before-Seen* With Er-Xuan Ping, SVP, Barium Titanate (BTO) Development Backdrop: the U.S. government just announced a $2B push into domestic quantum computing manufacturing - but what does that actually fund? The @CommerceGov Department recently awarded PsiQuantum $100M to accelerate development of BTO, giving a rare look into the underlying manufacturing stack required to scale fault-tolerant quantum computing. We profiled PsiQuantum last September following its $1B Series E, including how the company produces the world’s highest-performing optical switch - a core component of its silicon photonics platform. PsiQuantum is currently the only company or institution in the world manufacturing this BTO material for optical switches at 300mm scale. While the company built this silicon photonics platform for fault-tolerant quantum computing (FTQC)*, the implications may extend far beyond quantum itself. As AI data centers increasingly shift from copper to optical networking, PsiQuantum’s photonics stack could also become foundational infrastructure for next-generation AI systems. *Fault-tolerant quantum computing (FTQC) refers to quantum computers that can continue operating accurately even when individual quantum bits (“qubits”) are noisy or error-prone.

PsiQuantum has been named to the @SVDG_official's NatSec100 list—for the fourth year in a row. In the past year alone, our company has: — Signed a $100 million Letter of Intent with the Department of @CommerceGov to advance U.S. quantum computing and semiconductor leadership — Signed a $31.8 million contract with @DARPA under the most advanced stage of the Quantum Benchmarking Initiative — Broken ground in South Chicago on America's largest quantum computing project — Announced new partnerships with @LockheedMartin and @Airbus U.S. leadership in quantum technology is essential for national security and economic prosperity. And from systems, to state-of-the-art components, to partnerships, to infrastructure projects, we're building like it. natsec100.org/

From our future partnership with the Department of @CommerceGov to accelerate the domestic manufacturability our state-of-the-art components and strengthen the U.S. supply chain, to our collaboration with @nvidia across quantum computing and silicon photonics, PsiQuantum is scaling hard-won capabilities that will help write the next chapter in the history of computing.

PsiQuantum is manufacturing America's quantum future. Today, the company announced that we have signed a Letter of Intent with the U.S. Department of @CommerceGov for $100 million in proposed federal incentives under the CHIPS and Science Act to advance American quantum computing and semiconductor leadership. With this planned funding, combined with PsiQuantum's existing U.S.-anchored supply chain, the company will accelerate the domestic manufacturability and performance of our state-of-the-art components, including Barium Titanate (BTO) for higher-performance optical switches, high-temperature single-photon detectors, and advanced packaging approaches.
