Marin Ivezic

I am the Founder of Applied Quantum (AppliedQuantum.com), a research-driven consulting firm empowering organizations to seize quantum opportunities and proactively defend against quantum threats. A former quantum entrepreneur, I’ve previously served as a Fortune Global 500 CISO, CTO, Big 4 partner, and leader at Accenture and IBM. Throughout my career, I’ve specialized in managing emerging tech risks, building and leading innovation labs focused on quantum security, AI security, and cyber-kinetic risks for global corporations, governments, and defense agencies. I regularly share insights on quantum technologies and emerging-tech cybersecurity at PostQuantum.com.

Qubits: A Brief Introduction for Cybersecurity Professionals

A qubit is the quantum analog of a classical bit – it’s the basic unit of quantum information. However, unlike a classical bit that can only be 0 or 1 at any given time, a qubit can exist in a…

Bell States: An Introduction for Cybersecurity Professionals

Bell states are a set of four specific quantum states of two qubits (quantum bits) that are entangled. In simple terms, an entangled pair of qubits behaves as one system, no matter how far apart they are. Bell states are…

Human Zombification as an Information Security Threat

China and Russia share an information security doctrine, one that is significantly different from Euro-Atlantic doctrines. In the Chino-Russian model of information space a discussion about population zombification does happen and it fits squarely within the domain of information security.…

Non-Executive Directors as Cyber Champions

As a non-executive director (NED) who often represents cybersecurity and emerging technology interests on boards, I’ve learned that even without being a deep technical expert, I must challenge management and ensure our company’s security posture is sound. In today’s high-risk…

Can we Rescue Diversity from its own Failings?

Don’t expect this to be either of the typical articles about diversity. I’m here not to fawn over its benefits nor to rant about who does or doesn’t get hired. I’m here, instead, to ask why we react to it…

Innovative Businesses Have Curious Employees

Several comments in response to my recent competency-focused post led me to also consider the importance of curiosity in the workplace. Interestingly enough, recent experiences have given me a chance to see firsthand the benefits of nurturing curiosity and how to do…

The World of Cyber-Physical Systems & Rising Cyber-Kinetic Risks

We live in a world in which the way we observe and control it is radically changing. Increasingly, we interact with physical objects through the filter of what computational systems embedded in them tell us, and we adjust them based…

Kuperberg’s Algorithm and its Impact on Post-Quantum Cryptography (PQC)

Kuperberg’s algorithm is an impressive quantum algorithmic achievement that expands the boundary of what quantum computers might do beyond the original realm of Shor’s algorithm. It demonstrates that even some non-trivial group problems (like the dihedral hidden subgroup problem) are…

Balancing Quantum Computing Hype and Hope

Quantum computing stands at the intersection of immense promise and intense hype. As someone who had led cybersecurity teams (including serving as an interim CISO for Fortune 500 companies) and was now investing in a quantum computing startup, I found…

MAS TRM Just Reset the Floor for Financial‑Sector Cybersecurity

I’ve spent the last few years in Singapore helping banks, insurers, and market infrastructure across APAC harden their environments. We’ve all said the same thing in private: we need a clear, enforceable baseline that trades vague “best practice” for concrete…

Why I Chose Photonic Quantum Computing

Choosing photonic quantum computing for my startup is equal parts ambition and pragmatism. The ambition is that photons, with their long coherence and networking talent, could unlock scalable quantum computers without the cryogenic baggage of other approaches. The pragmatism was…

Quantum Computing Hype and Fear: Same Song, New Verse

Another year, another wave of "quantum computers are about to crack all our encryption" fear-mongering. It’s 2012, and I’m getting déjà vu reading headlines proclaiming the imminent doom of RSA and other cryptography. I've been writing about this for at…

Cyber War – scaremongering or reality?

“Cyber war” is a term that is in recent days used so liberally that people may often wonder if these words are as menacing as they sound or used only as a tool to incite fear as a way to…

United We Secure: Why Cybersecurity Needs Information Sharing

The cyber battlefield is heating up. On one side, cyber criminals are pooling their knowledge like a well-oiled team; on the other, many organizations still act like lone wolves. I recall a fellow CISO remarking at a meeting, “I don’t…

Quantum Computers Intro

I remember the first time I heard the phrase “quantum computer” about a ten years ago. I pictured something out of a sci-fi movie - maybe a glowing box humming with mystical power. As a techie who spends a lot…
