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…

OpenSSL 3.5 Ships with Post-Quantum Cryptography On by Default
OpenSSL 3.5.0 ships with ML-KEM, ML-DSA, and SLH-DSA built in, and defaults TLS key exchange to hybrid PQC. For the millions of servers and applications running OpenSSL, PQC just went from "find a plugin" to "update your library."

Quantum Patents and IP Strategy: Safeguarding Innovation in a Crowded Field
Patents, when aligned with business goals, can attract investment, deter infringement, and provide leverage for collaboration. TTOs and innovators should view IP not just as legal protection but as a core part of innovation strategy – especially in a field…

Breaking RSA Encryption: Quantum Hype Meets Reality (2022-2025)
To put it plainly, if you encrypted a message with an RSA-2048 public key today, no one on Earth knows how to factor it with currently available technology, even if they threw every quantum computer and supercomputer we have at…

Post-Quantum Cryptography (PQC) Standardization – 2025 Update
Post-quantum cryptography (PQC) is here - not in theory, but in practice. We have concrete algorithms, with standards guiding their implementation. They will replace our decades-old cryptographic infrastructure piece by piece over the next decade. For tech professionals, now is…

NIST PQC Security Strength Categories (1–5) Explained
As part of its post-quantum cryptography (PQC) standardization, NIST introduced five security strength categories (often labeled Levels 1-5) to classify the robustness of candidate algorithms. Each category represents a minimum security level that a PQC algorithm’s cryptanalysis should require, defined…

ETSI publishes TS 103 744 v1.2.1: Hybrid key establishment for the quantum transition
ETSI’s Technical Committee CYBER has released ETSI TS 103 744 V1.2.1, a technical specification for quantum‑safe hybrid key establishment—methods that combine classical elliptic‑curve Diffie‑Hellman (ECDH) with post‑quantum key encapsulation (ML‑KEM) to derive shared keys that remain secure even if one…

PQC Is Necessary, But Not Sufficient – Building Quantum Resilience the Right Way
Simply "dropping in" PQC algorithms will not magically make systems quantum-safe. Real security hinges on how these new primitives are implemented, integrated, and layered into our systems. A quantum-resistant algorithm on paper can still fail in practice due to coding…

Jinan-1’s real-time QKD demo is a “practicality milestone,” not just a distance headline
A new Nature paper - and a companion Nature news story - highlights what might be the most “deployment-shaped” leap in satellite quantum key distribution (QKD) since the Micius era: Jinan‑1, a quantum microsatellite, has demonstrated real-time space-to-ground QKD using portable (~100 kg) optical ground…

New Study Shows Post‑Quantum Cryptography (PQC) Doesn’t Have to Sacrifice Performance
The new performance analysis of Kyber and Dilithium is a welcome addition to the PQC literature. It confirms that post‑quantum security and good performance are not mutually exclusive, especially when using optimized implementations. In fact, Kyber and Dilithium often outperform…

Quantum Programming: An In-Depth Introduction and Framework Comparison
Quantum programming is an emerging discipline that challenges developers to think beyond classical bits and deterministic algorithms. Instead of manipulating binary 0s and 1s, quantum programmers work with qubits that can exist in multiple states at once and harness phenomena…
