Washington begins to treat quantum technology as a strategic priority, as the United States is moving from a phase defined by research into one defined by commercialization and deployment.”

- Quantum Insider

March maintained the rapid development momentum the quantum industry has come to be associated with, from the government starting to treat quantum technology as a strategic priority to the development and deployment of the technology for different commercial and industrial applications. The U.S. government is beginning to treat quantum technology as a strategic priority, as the nation transitions from a phase defined by research to one characterized by commercialization and deployment.

At the same time, more investment inflows are pouring into the advancement of quantum technology and its underlying infrastructures: UK pledges £2 billion for quantum innovation, SEALSQ expands its Quantum Fund to $200 million to invest across the quantum technology stack, Horizon Quantum raises $120 million to go public via SPAC, IQM secures €50 million financing to accelerate global growth, and Quantinuum establishes a new R&D center in Singapore to expand its global footprint.

On the commercial side, March saw more collaborations between startups and companies in and outside of the quantum industry. BTQ Technologies added to the WisdomTree Quantum Computing Fund (WQTM), Atom Computing entered a strategic collaboration with Cisco to advance scalable, networked, and distributed quantum computing, and Xanadu and AMD are combining efforts to accelerate quantum computing for aerospace and engineering. Also, following NIST-approved PQC standards, and as more organizations are looking to migrate their cryptographic infrastructure, there are now more players in the quantum-safe cryptography migration landscape, from PQC specialists to QKD hardware providers to cloud and infrastructure vendors.

March kept pace with the increased momentum in investments, partnerships, and the gradual deployment of quantum technologies outside research laboratories for commercial and industrial applications.

BTQ Technologies Announces First Deployment of BIP 360 on Bitcoin Quantum Testnet v0.3.0

BTQ Technologies Corp. has announced that Bitcoin Quantum testnet v0.3.0 includes the first functional implementation of Bitcoin Improvement Proposal (BIP) 360, the quantum-resistant Pay-to-Merkle-Root (P2MR) output type, which was merged into Bitcoin's official BIP repository earlier this year.

Bitcoin Quantum's BIP 360 implementation includes:

  • Full P2MR consensus: SegWit version 2 outputs with bc1z address encoding (bech32m), Merkle root commitment verification, and control block validation.

  • All five Dilithium post-quantum signature opcodes are enabled in the P2MR tapscript context, providing real quantum-resistant signature verification inside the script tree.

  • End-to-end CLI wallet tooling: Complete wallet RPC support enables users to create, fund, sign, and spend P2MR transactions on testnet today.

  • Live, testable infrastructure: The release includes functional validation across address creation, funding, transaction construction, signing, mempool acceptance, broadcast, and confirmation.

  • Network activation: BIP 360 functionality has been activated across Bitcoin Quantum's testing environments.

According to Olivier Roussy Newton, CEO and Chairman of BTQ Technologies:

BIP 360 represents the Bitcoin community's most significant step toward quantum resistance and we've turned it from a proposal into running code. Bitcoin Quantum exists to prove that quantum-safe solutions work in practice, not just on paper. By shipping a full BIP 360 implementation on testnet, we're giving the entire industry a live environment to validate these critical protections before the quantum threat arrives.

BTQ Technologies Added to WisdomTree Quantum Computing Fund (WQTM), Expanding U.S. Thematic ETF Exposure
