Capability B.1: Quantum Error Correction (QEC)
Quantum Error Correction (QEC) is the first and arguably most critical capability in the roadmap toward a cryptographically relevant quantum computer (CRQC). Without QEC, a large-scale quantum computer cannot reliably perform the billions of operations needed to break modern encryption…

Stuxnet and the Birth of Cyber-Kinetic Weapons
Stuxnet was the first true cyber-kinetic weapon, designed to cripple the Iranian – and perhaps also the North Korean – nuclear weapon programs. It succeeded in slowing the Iranian program, although it was discovered before it could deal the program…

Leadership in the Age of Artificial Intelligence (AI)
AI’s effect on the workplace will not be limited merely to repetitive, production line-type jobs. Increasingly, it also enters the realm of highly trained knowledge workers. It will also affect those who manage workers currently employed in such jobs. AI…

How Telecom Operators Can Strike Back with IoT, Fog & Cyber
Telecom operators sat back as the new over-the-top (OTT) service providers, internet and tech companies slowly ate away at their business, particularly in the B2C space. A combination of institutional laziness and poor execution on promising initiatives gave these new…

Shor’s Algorithm: A Quantum Threat to Modern Cryptography
Shor’s Algorithm is more than just a theoretical curiosity – it’s a wake-up call for the security community. By understanding its principles and implications, we can appreciate why the cryptographic landscape must evolve. The goal of this guide is to…

Quantum Fourier Transform (QFT)
Quantum Fourier Transform (QFT), like a physical Fourier transform, takes a time-domain wave and represents it in the frequency domain. In the quantum case, the “time-domain” is the computational basis amplitude distribution, and the “frequency-domain” is another basis where the…

Grover’s Algorithm and Its Impact on Cybersecurity
Grover’s algorithm was one of the first demonstrations of quantum advantage on a general problem. It highlighted how quantum phenomena like superposition and interference can be harnessed to outperform classical brute force search. Grover’s is often described as looking for…

Hadamard Gate: The Gateway to Superposition
The Hadamard gate takes a qubit and puts it into an equal superposition of “0” and “1” (with a relative phase of + or -). It has a simple matrix but a profound impact: it enables parallelism and interference in…

The Hidden Subgroup Problem (HSP): One Framework to Break Them All
Every public-key cryptosystem deployed today - RSA, Diffie-Hellman, and elliptic curve cryptography - falls to a single mathematical framework called the Hidden Subgroup Problem (HSP). This is not a coincidence: Shor's algorithm, in each of its variants, works by exploiting…

Quantum-Safe vs. Quantum-Secure Cryptography
In 2010, I was serving as an interim CISO for an investment bank. During that time, I was already trying to figure out the risks posed by quantum computing. One day, I was approached by a vendor who, with great…

History of Cyber-Kinetic Incidents and Research
The fact that cyber-kinetic attacks rarely appear on mainstream news doesn’t mean they don’t happen. They happen more frequently than you would think. Many, for various reasons, aren’t even reported to agencies charged with combatting them. This hinders security experts…
