The Easiest Job in Quantum Computing – Being a Cynic
Don’t mistake the noise of cynicism for the signal of intelligence. If someone validates themselves as a useless cynic - unwilling to provide anything beyond scoffs and derision - don’t waste your energy getting dragged into their performative pessimism. Instead, direct your attention to the genuine skeptics and curious contrarians who challenge ideas in good faith. Engage with those asking hard questions and with the enthusiasts…

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 one commentator quipped ), but it’s quickly moving from speculation to reality. A few bold…

Magic States: A Key to Universal Fault-Tolerant Quantum Computing
Magic states are special quantum states that enable the universal operations needed for any quantum algorithm, yet which are not themselves easy to produce or protect. In essence, magic states supply the "extra quantum sauce" that elevates a protected quantum computer from what could be emulated on a classical computer to a machine that can outperform classical supercomputers. Recent breakthroughs - from theory and small-scale…

Quantum Winter Warning: Why Overhype and the QCI Saga Could Chill Quantum Computing
The saga of Quantum Computing Inc. is a stark illustration of what happens when hype becomes unmoored from truth. If the quantum field falls into the trap of overselling and under-delivering, we will hand ammunition to detractors and possibly induce the very “quantum winter” we all want to avoid. Investors and enthusiasts should indeed be excited by progress, but also clear-eyed: practical quantum computing is…

The Many Faces of Decoherence
Quantum computers hold enormous promise, but they face a stubborn adversary: decoherence. This is the process by which a qubit’s fragile quantum state (its superposition or entanglement) leaks into the environment and effectively "forgets" the information it was carrying. For today’s leading quantum hardware modalities – superconducting circuits, trapped-ion qubits, neutral atoms in optical traps, photonic qubits, and semiconductor spin qubits in silicon – decoherence…

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, searching databases, simulating quantum systems, solving certain optimization problems, and more we have yet to…

The Rise of Logical Qubits: How Quantum Computers Fight Errors
Logical qubits are the linchpin for delivering on the promise of quantum computing. They are the qubits as we wish we had them – long-lived and trustworthy – brought to life by the ingenuity of quantum error correction. By encoding information across many imperfect qubits, scientists have shown they can create a single superior qubit, and the more qubits you throw at it, the better…

Why I Founded Applied Quantum – The First Pure-Play, End-to-End Quantum Consultancy
Applied Quantum is a firm that for the first time would be 100% dedicated to quantum technology services – not as a sideline, not as one emerging tech practice among many, but as the entire mission of the company, and it would cover the field end-to-end. We founded Applied Quantum to be the first and only end-to-end pure-play quantum professional services firm precisely because generalist…
