    What Quantum Computers Can Do Better Than Classical Computers

    Quantum computers already outperform classical computers on a few specialized tasks, and over the coming years that list of tasks will grow. They excel at problems where superposition and entanglement let them explore a vast landscape of possibilities in parallel and use interference to extract an answer – factoring numbers,…

    Why Companies May Need a Chief Quantum Officer (CQO)

    In my opinion, forward-thinking organizations should consider creating a Chief Quantum Officer (CQO) role. Much like those historical electricity executives, a CQO would spearhead the adoption of a disruptive technology that is revolutionary, promising - but widely misunderstood. It’s a provocative idea (even “a job title from Star Trek,” as…

      Colliding Waves: How Quantum Interference Powers Quantum Computing

      Quantum interference remains the cornerstone of quantum computing’s promise. It’s the feature that distinguishes quantum computation from just a random quantum jumble. A quantum computer is not powerful simply because it can have many states at once – if that were all, measuring would give a random one and it wouldn’t be useful. It’s powerful because those many states can interfere in a orchestrated way…

      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 combination of both 0 and 1 states simultaneously. This property is called superposition.

      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 the simplest and most extreme examples of this phenomenon​. They are fundamental to quantum mechanics because they exhibit correlations between particles that have no classical…

      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 easier for quantum computers than for classical ones, albeit not easy in an absolute sense. In the context of cryptography, Kuperberg’s result serves as a…

      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 myself navigating two contrasting narratives. On one hand, I am bullish on the future of quantum technology - convinced that within 15-20 years we’d see…

      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 that by immersing myself in this cutting-edge field, I could better prepare for the quantum revolution that will shake up cybersecurity. Photonic qubits offer a…
