Quantum Simulation Using Decision Diagrams. Innovation in Verification

Quantum Simulation Using Decision Diagrams. Innovation in Verification
by Bernard Murphy on 05-28-2026 at 6:00 am

Innovation New

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

Quantum Gathering Momentum Amid Concerns for the Grid
by Bernard Murphy on 05-20-2026 at 6:00 am

Quantum attack on the power 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

Sensing. A Quantum Tech Ready for Market?
by Bernard Murphy on 05-13-2026 at 6:00 am

Quantum sensor analyzing a chip

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?

Could Neutral Atoms Take the Lead in Quantum Computing?
by Bernard Murphy on 04-22-2026 at 10:00 am

Neutral atom QC architecture

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

Hacker attacking edge devices

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

Calibrating Quantum Computing Activity in Financial Services
by Bernard Murphy on 04-14-2026 at 6:00 am

Quantum portfolio optimization

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?

An Upper Bound on Effective Quantum Computation?
by Bernard Murphy on 04-07-2026 at 6:00 am

QC with entanglement ceiling

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

Another Quantum Topic: Quantum Communication
by Bernard Murphy on 03-02-2026 at 6:00 am

Quantum teleportation

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
