QEDMA Raises $26 Million for Noise Reduction Software
First on the agenda is QEDMA, an Israeli startup focused on error suppression in quantum computers, which closed a $26 million Series A round led by Glilot+ with backing from IBM, Korea Investment Partners, and TPY Capital. The company’s platform-agnostic software learns the noise profile of individual quantum devices, then reshapes algorithms to suppress and mitigate errors. According to QEDMA, this can boost computational scale by up to 1,000x on existing hardware. The company plans to demonstrate quantum advantage in upcoming collaborations. QEDMA is also one of the first contributors to IBM’s Qiskit Functions, a cloud framework for running modular quantum tasks.
IonQ Locks in $1 Billion Cash Infusion
IONQ announced a $1.0 billion equity offering, including common stock and pre-funded warrants sold at a 25% premium. The deal gives the company roughly $1.68 billion in pro forma cash as of Q1 2025. The financing, led by Heights Capital Management and underwritten by J.P. Morgan, supports IonQ’s expansion in both quantum computing and networking. Company leadership described it as the largest single-institution investment in quantum technology to date and a vote of confidence in IonQ’s technology roadmap and recent acquisitions.
BTQ Technologies Debuts Quantum Proof-of-Work Simulator
BTQ Technologies (BTQQF) launched a simulator for its Quantum Proof-of-Work Simulator (QPoW), a mining framework designed to resist quantum attacks. The system replaces traditional hashing with boson sampling, a task that can only be run efficiently by photonic quantum devices. QPoW aligns with post-quantum regulatory standards from the EU and NIST, and was adopted as the first consensus item by the QuINSA standards group. Unlike conventional mining, the QPoW approach links security difficulty to photon count rather than energy usage, reducing power needs while increasing quantum resilience.
India to Launch First Quantum-Secure Satellite
India is developing its first indigenous quantum-resilient satellite through a partnership between Space TS and Synergy Quantum. The project focuses on embedding post-quantum encryption into satellites, ground control, and mission planning systems. While neither company is publicly traded, the move reflects national trends. Governments are moving fast to future-proof space infrastructure from quantum threats. EU and U.S. regulators are also requiring the use of post-quantum cryptography across military and financial networks by 2030.
EU Kicks Off SUPREME Project for Chip Manufacturing
The EU-backed SUPREME initiative, led by Finland’s VTT, will invest in superconducting quantum chip fabrication. The project involves 23 partners from eight countries, including companies like Infineon (IFNNY) and IQM. The first fabrication processes are set to go live by 2027, giving European companies access to stable, high-yield quantum chip design kits. For investors, the takeaway is clear: regional ecosystems are being built now, and they could shape the supply chain for years to come.
