Quantum Computing Modalities: Spin Qubits in Other Semiconductors & Defects
In addition to silicon, spin qubits can be realized in other solid-state systems. One well-known example is the nitrogen-vacancy (NV) center in diamond, which is a point defect where a nitrogen atom next to a vacancy in the carbon lattice…

Quantum Computing Modalities: Silicon-Spin
Silicon spin qubits bring quantum computing onto the same fabrication lines that produce every classical processor on Earth. The first logical operations arrived in 2026. Here's the technology, the vendors, the CMOS thesis, and what it means for the path…

Post-Quantum Cryptography (PQC) and Network Connectivity: Challenges and Impacts
PQC brings new dependencies between cryptography and network connectivity. Unlike the relatively small and efficient crypto of the past, post-quantum algorithms force us to consider link capacity, latency, and device limitations as first-class concerns in security design. Some network environments…

Quantum Computing Modalities: Measurement-Based Quantum Computing (MBQC)
Measurement-Based Quantum Computing (MBQC), also known as the one-way quantum computer, is a paradigm where quantum computation is driven entirely by measurements on an entangled resource state. Instead of applying a sequence of unitary gates to a register of qubits,…

New Coalition Launched to Tackle Post-Quantum Cryptography
The MITRE Corporation has announced the formation of the Post-Quantum Cryptography Coalition, a collaborative effort to address the imminent threats posed by quantum computing to current cryptographic systems. The coalition aims to accelerate the development and adoption of quantum-resistant cryptographic…

Quantum Computing Modalities: Neutral Atom (Rydberg)
Neutral-atom quantum computers operate at room temperature, scale to thousands of qubits, and hold the record for verified logical qubits. Here's the technology, the vendors, and why this modality is closing the gap on superconducting hardware faster than anyone expected.

Quantum Computing Modalities: Quantum Annealing (QA)
Quantum annealing (QA) is a special-purpose quantum computing paradigm designed to solve optimization problems by exploiting quantum tunneling and the adiabatic principle. It's a special case of Adiabatic Quantum Computing (AQC). The idea is to encode a problem (typically an…

Saudi Arabia Vision 2030: Cybersecurity at the Core of Transformation
Last week, the Saudi Data and Artificial Intelligence Authority (SDAIA) launched a nationwide awareness campaign called “Ask Before”, intended to educate the public about the significance of personal data ahead of the implementation of a new national personal data protection system. Emphasizing…

AI Security 101: Where Each Attack Belongs and What Contains It
The mechanisms behind AI attacks have not changed since the spam filters of 2008. What changed is the blast radius. A map of where each attack belongs, what contains it, and what the evidence actually supports.

Why We Seriously Need a Chief AI Security Officer (CAISO)
With AI’s breakneck expansion, the distinctions between ‘cybersecurity’ and ‘AI security’ are becoming increasingly pronounced. While both disciplines aim to safeguard digital assets, their focus and the challenges they address diverge in significant ways. Traditional cybersecurity is primarily about defending…

Quantum Computing Modalities: Quantum Walk QC
Quantum walks are the quantum-mechanical counterparts of classical random walks. In a classical random walk, a "walker" (such as a particle or an agent) moves step by step in a certain space (like a line or a graph) with some…

Neural Trojans: Backdoors That Survive Safety Training
A backdoor is a specific trigger implanted in a model that stays dormant until it fires. The 2024 result that matters is that standard safety training did not reliably remove one, and adversarial training taught the model to hide it…

Quantum Computing Modalities: Fibonacci Anyons
Fibonacci anyons are a type of non-Abelian anyon – exotic quasiparticles that can exist in two-dimensional systems and have exchange statistics beyond bosons or fermions. When two non-Abelian anyons like Fibonacci anyons are exchanged (braided) in space, the quantum state…

What Will Really Happen Once Q-Day Arrives – When Our Current Cryptography Is Broken?
As the world edges closer to the era of powerful quantum computers, experts warn of an approaching “Q-Day” (sometimes called Y2Q or the Quantum Apocalypse): the day a cryptographically relevant quantum computer can break our current encryption. Unlike the Y2K…

Quantum Computing Modalities: QA With Digital Boost (“Bang-Bang” Annealing)
Digital Boost (“Bang-Bang” Annealing) refers to augmenting or replacing the continuous, gradual annealing schedule with discrete pulses or abrupt changes in the control parameters – essentially applying bang–bang control to quantum annealing. In control theory, a bang–bang controller is one…
