Quantum gate simulation complexity explodes as qubit counts increase. One way to manage this complexity in simulation on classical computers is through use of decision diagrams in place of matrices. Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and lecturer… Read More
Quantum Gathering Momentum Amid Concerns for the Grid
I posted recently on an eye-catching advance in quantum computing, around neutral atom systems which might accelerate the transition to production-grade fault-tolerant quantum computing (QC). There are some further updates on this front, also I listened in on a panel considering quantum-based hacking vulnerability in the… Read More
PQShield unveils ultra-small PQC embedded security breakthroughs at Embedded World 2026
As the threat of quantum computing to modern cybersecurity becomes increasingly real, the technology industry is accelerating efforts to develop cryptographic systems capable of resisting quantum attacks. One of the most significant developments in this field was presented at Embedded World 2026 in Nuremberg, Germany, … Read More
Sensing. A Quantum Tech Ready for Market?
While the quantum world revolves around quantum computing, (QC) there are a couple of other quantum technologies of note. I covered one of these, quantum communication, in a recent blog. Here I’ll introduce the other, quantum sensing. The goal is to use the high sensitivity of an individual quantum state to external factors such… Read More
Could Neutral Atoms Take the Lead in Quantum Computing?
As of my recent posts on quantum computing (QC), superconducting QC is the leading technology contender, exemplified in systems from IBM, Google, and Fujitsu. Other technologies such as ion trap, neutral atom, photonic and quantum dot have generally been viewed as intriguing but second tier. I just read a very recent paper suggesting… Read More
Effective Defense Against Hacks at the Edge
IoT permeates every aspect of our lives, in payment systems, access authorization, vehicles, utilities, factories, hospitals, and in so many other fields. Which makes these systems attractive targets for hacking and social disruption while also challenging to protect given the highly constrained resources that many such… Read More
Calibrating Quantum Computing Activity in Financial Services
I was invited to listen in on an event hosted by Fujitsu and Quantum Insider on the reality of Quantum Computing (QC) in financial services today. This market is a good test for QC since multiple possible high value applications have been suggested. The panel was chaired by Brian Lenehan, (Founder and Chair, Quantum Strategy Institute),… Read More
An Upper Bound on Effective Quantum Computation?
You may think that quantum theory is fully understood but that view is not quite right. There remain open questions around the uncertainty principle, wave-particle duality, measurement collapse, and harmonizing quantum mechanics and gravitation. These concerns may seem very abstract and irrelevant to everyday applications… Read More
Another Quantum Topic: Quantum Communication
In my recent series on quantum computing (QC), I intentionally overlooked a couple of adjacent topics: quantum communication and quantum sensing. These face some of the same challenges as QC, however I noticed a recent report on a test quantum network implemented by Cisco and Qunnect which led me to find more from Cisco on their … Read More
PQShield on Preparing for Q-Day
Following my series on quantum computing (QC), it is timely to look again at what is still the most prominent real-world concern around this technology: its ability to hack classical security methods for encryption and related tasks. Given what I have written on the topic, an understandable counter would be that QC is still in development… Read More
