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.

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…

Quantum Computing Hardware Update

In summary, as 2006 ends I remain confident yet realistic. We’ve seen genuine, hard-won progress in quantum hardware: superconducting circuits entangling, ions scaling up with superb control, photons performing logic, and even completely different technologies proving their quantum chops. We’ve…

Reflections on AI Progress

Looking back over the years, I’m struck by how far AI has come and yet how far it still has to go. In late 2005, AI is best described as a powerful set of tools - pattern recognition, optimization, inference…

Are Quantum Computers a Real Threat?

Our conclusion is that quantum computers are not an imminent threat to cybersecurity. They are a fascinating technology and potential threat in the long term, but certainly not something that keeps me awake at night today. For our clients such…

The Decline of Real Penetration Testing

As the leader of Cyber Agency, one of the largest penetration testing and red teaming specialist outfis, I have a bone to pick with where our industry is headed. Back in the late 90s and early 2000s, "pentesting" actually meant…

How can you get the Most out of Interim Managers?

Are you hiring and using interim managers wisely? Why is it that some companies attain exceptional results from interim manager hirings and some are disappointed? It has little to do with the quality of interim manager candidates. The only way…
