“Several quantum-computing companies are in talks to give the Commerce Department equity stakes in exchange for federal funding, a signal that the Trump administration is expanding its interventions in what it sees as critical segments of the economy. ”

- Wall Street Journal

Quantum developments in October showed how fast the field of quantum technologes is moving and being integrated into HPC and real world workflows.

Google claimed a new quantum advantage benchmark with 13,000x improvement over classical systems, while NVIDIA launched a hybrid quantum-classical interconnect standard, signaling the future of integrated infrastructure.

Cloudflare revealed that over half of human-originated web traffic is now encrypted using post-quantum secure protocols. Meanwhile, venture and policy momentum accelerated: Quantum Computing Inc. raised $750M to expand its hardware and software platforms, while New Mexico launched a $25M quantum venture studio backed by a $315M public quantum fund.

The takeaway is that October shows that integration is top of mind, not just research. Quantum is being wired into the fabric of cloud networks, cybersecurity stacks, capital markets, and national strategy.

BTQ Technologies announced the first successful demonstration of a quantum‑resistant Bitcoin implementation, replacing Bitcoin’s vulnerable ECDSA signatures with the NIST‑approved ML‑DSA algorithm to protect the network’s $2.4 trillion market. Bitcoin Quantum Core 0.2 completes the full flow of wallet creation, transaction signing, verification, and mining using post‑quantum cryptography, providing a standards‑based path to secure the Bitcoin ecosystem against “harvest‑now, decrypt‑later” attacks.

The roadmap includes a Q4 2025 testnet and audit, Q1 2026 enterprise pilots, and Q2 2026 mainnet deployment with migration tools for exchanges and wallets. BTQ has also established the BTQ Foundation to coordinate industry‑wide adoption of quantum‑safe standards across digital assets, building on its leadership in QuINSA and NIST PQC development.

Quantum in Industry

D-Wave Deploys Advantage2 in Europe in €10M Deal

On October 15, 2025, D‑Wave announced a strategic agreement with Swiss Quantum Technology SA (SQT) to deploy its Advantage2 annealing quantum computer in Europe.

  • Commitment: €10 million (≈ US$11.6 million) for quantum‑computing‑as‑a‑service over approximately five years.

  • Hardware: The Advantage2 system features 4,400 + qubits, D‑Wave’s largest annealing quantum processor to date.

  • Cloud access: The system will be accessible via D‑Wave’s Leap™ real‑time quantum cloud service.

The deal provides European enterprises and researchers with direct access to D-Wave’s hybrid solvers, targeting optimization problems in logistics, supply chains, and finance. By partnering with SwissQT, D-Wave strengthens its footprint in an increasingly strategic market ahead of emerging EU procurement opportunities.

This transaction marks a significant step in commercialising annealing quantum computing in Europe. With Switzerland aiming to become a quantum hub, the installation positions Advantage2 as a key player in the region’s applied quantum strategy.

📊Market Insights

Cloudflare Releases PQC Report Establishing Majority of Internet Traffic is Now Post-Quantum Secure

Cloudflare reported that over 50% of human-originated web traffic is now encrypted using post-quantum secure protocols. This milestone comes ahead of many compliance timelines and marks the largest known real-world deployment of PQC.

By moving the majority of global web traffic onto PQC‑protected channels years before most standards deadlines, Cloudflare has effectively made quantum‑safe encryption the new baseline for the internet.

Boston Consulting Group (BCG) Publishes “How Quantum Computing Will Upend Cybersecurity”

BCG released an October 15 2025 analysis that warns major cryptographic standards could be vulnerable to quantum attacks by around 2035 and estimates that delaying a transition to post‑quantum cryptography (PQC) could double costs for enterprise IT portfolios.

By red‑lining the timeline and cost of quantum cryptography migration, the report reframes quantum risk from a distant research debate into an immediate enterprise risk. Firms that treat PQC as “eventually” will likely face increased breach risk and higher remediation cost than those that act now.
