Quantum Key Distribution (QKD): Why Countries Differ on Its Future
Quantum Key Distribution (QKD) - a method of securing communications using quantum physics - has become a flashpoint of debate worldwide. Recent news (like Google’s announcement favoring post-quantum algorithms over QKD) highlights how divided opinions are. Some nations are investing heavily in QKD networks as the next frontier of secure communications, while others remain skeptical and prioritize post-quantum cryptography (PQC). United States and Allies: Emphasizing…

Data Discovery & Classification: Foundations for Quantum Readiness
Every CISO knows the old adage: “You can’t protect what you don’t know you have.” In the quantum readiness era, this doesn’t just apply to hardware and software assets - it applies equally to data. As organizations brace for cryptography-breaking quantum computers, they must first discover and classify their data to understand what’s at stake. Data is now scattered across on-prem servers, cloud buckets, employee…

Quantum Repeaters: The Key to Long-Distance Quantum Comms
Quantum repeaters are specialized devices in quantum communication networks designed to extend the distance over which quantum information (qubits) can be sent without being lost or corrupted. They tackle a fundamental challenge: photons carrying qubits tend to get absorbed or scatter as they travel through fiber or air, and quantum states can decohere (lose their quantum properties) due to environmental noise.

What is Entanglement-as-a-Service (EaaS)?
Entanglement-as-a-Service is transitioning from a fascinating concept to a nascent reality. Its technical foundations are solidly rooted in quantum physics, its current development is accelerating through global research efforts, and its promise has caught the attention of the telecommunications industry and beyond. While challenges remain in scaling and integration, the trajectory is clear: EaaS and quantum networks will likely be as transformative in the 21st…
