U.S. commits $2B to quantum foundries, betting supply chain controls the race

The Department of Commerce awarded $2 billion in CHIPS incentives to nine quantum companies, anchored by IBM's new Anderon foundry, reshaping who can access quantum wafer fabrication globally.

Trump gives quantum chip makers $2B, takes equity stakes in return

Trump administration awards $2 billion in quantum computing manufacturing grants to nine firms while taking equity stakes, departing from traditional CHIPS Act subsidy structure.

IBM, Cleveland Clinic model 12,635-atom protein on quantum hardware

IBM and Cleveland Clinic simulated the largest biological molecule ever modeled with quantum computers, achieving 40x larger systems in six months and signaling that quantum computing is moving from theory into practical drug discovery.

Chad Rigetti's Sygaldry raises $139M to shrink AI's power appetite

Chad Rigetti, the physicist behind Rigetti Computing, has launched Sygaldry Technologies with $139M in funding to build quantum-accelerated servers that reduce AI's energy consumption inside data centers rather than replace classical chips.

IonQ Links Two Quantum Computers via Light, Wins DARPA Contract

IonQ demonstrated the first photonic interconnection of two commercial quantum computers and secured a DARPA HARQ contract, triggering a 20% stock surge and signaling that quantum networking—not just qubit count—is now the competitive frontier.

Rigetti's 108-Qubit System Reaches Market: The Timing Matters More Than The Qubits

Rigetti Computing deployed its Cepheus-1-108Q on Amazon Braket on April 7, 2026—a real commercial system with 99.1% two-qubit gate fidelity. The milestone is technically solid. What it actually reveals is the gap between marketing and the path to quantum advantage.

IQM Compiles Shor's Algorithm at RSA-2048 in Gate-Level Detail

IQM Quantum Computers and Fraunhofer FOKUS released Qrisp 0.8 on April 5, generating the first gate-by-gate circuit for Shor's algorithm at 2048-bit key length — translating cryptographic threat from theoretical to engineered.

CavilinQ Raises $8.8M to Build the Missing Layer in Quantum Scaling

CavilinQ closed an $8.8M seed round on April 2, 2026, to develop photonic interconnects linking quantum processors into modular clusters—solving the bottleneck that has prevented quantum computing from scaling beyond isolated machines.
