Quantum Sovereignty
Quantum Human Capital Controls as Geopolitics
Quantum sovereignty is talent-constrained. In the race for quantum technology leadership, a skilled workforce has become a strategic asset - and a policy battleground. Nations are increasingly treating talent as a key lever of geopolitics, shaping immigration visas, research-security screening,…

Quantum Computing Modalities: Superconducting Cat Qubits
Cat qubits encode quantum information in Schrödinger's cat states inside superconducting resonators. Bit-flip errors are suppressed by the physics, not by error correction. Alice & Bob and AWS are betting this approach could cut the path to fault tolerance by…

Europe’s New Cryptographic Rulebook Just Made PQC Official
30 Apr 2025 - For years, the EU's position on post-quantum cryptography could be summarized as "we're watching closely." That changed in April 2025, when the European Cybersecurity Certification Group - the body that decides which cryptographic mechanisms are acceptable…

The Enormous Energy Cost of Breaking RSA‑2048 with Quantum Computers
The energy requirements for breaking RSA-2048 with a quantum computer underscore how different the post-quantum threat is from conventional hacking. It’s not just about qubits and math; it’s about megawatts, cooling systems, and power grids. Today, that reality means only…

The Many Faces of Decoherence
Quantum computers hold enormous promise, but they face a stubborn adversary: decoherence. This is the process by which a qubit’s fragile quantum state (its superposition or entanglement) leaks into the environment and effectively "forgets" the information it was carrying. For…

What Quantum Computers Can Do Better Than Classical Computers
Quantum computers already outperform classical computers on a few specialized tasks, and over the coming years that list of tasks will grow. They excel at problems where superposition and entanglement let them explore a vast landscape of possibilities in parallel…

The Rise of Logical Qubits: How Quantum Computers Fight Errors
Logical qubits are the linchpin for delivering on the promise of quantum computing. They are the qubits as we wish we had them – long-lived and trustworthy – brought to life by the ingenuity of quantum error correction. By encoding…
