Quantum networking is no longer theoretical — here's what it means for your business

Our name has always pointed at something we believe: the future of networking and the future of quantum technology are on a collision course. That's no longer a bet on the distant future — it's happening in 2026.

Cisco built a switch for quantum computers

In April 2026, Cisco introduced the Universal Quantum Switch — a prototype designed to solve one of the hardest problems in quantum networking: getting different quantum computers to talk to each other. Quantum machines from different vendors encode information in incompatible ways, and until now, no switch could translate between those formats without destroying the fragile quantum state in the process.

Cisco's switch does this at room temperature, over standard telecom fiber, with reported signal degradation under 4% — meaning it could plug into infrastructure that already exists rather than requiring exotic new cabling. Cisco also demonstrated a real fiber link between Brooklyn and Manhattan, moving entangled photon pairs thousands of times faster than earlier lab experiments.

The more urgent story: your encryption has a deadline

While quantum computers capable of breaking today's encryption are still likely years away, the security transition they're forcing is already underway. NIST finalized its first three post-quantum cryptography standards in 2024 (known as ML-KEM, ML-DSA, and SLH-DSA), and major providers — Cloudflare, Google, and Apple among them — have already begun rolling out quantum-safe protections to production traffic.

The reason this can't wait for quantum computers to actually arrive is a threat model called "harvest now, decrypt later." Adversaries can capture encrypted data today and simply store it, waiting for quantum computing to mature enough to decrypt it later. If your business handles data that needs to stay confidential for years — client contracts, financial records, health information, intellectual property — that data is already exposed to this risk, even though the decryption capability doesn't exist yet.

Where NetQuanta fits in

We're not a quantum computing company, and we won't pretend a small business needs a quantum network today. But understanding where enterprise infrastructure is heading — and translating that into what actually matters for a growing business now — is exactly the kind of forward-looking context we bring into every network design and security conversation.
