I have written earlier in this series that quantum error correction (QEC), a concept parallel to ECC in classical computing, is a gating factor for production quantum computing (QC). Errors in QC accumulate much faster than in classical systems, requiring QEC methods that can fix errors fast enough to permit production applications.… Read More
Quantum Computers: Are We There Yet?
R&D for any fundamentally new technology takes time, especially for hardware; over 10 years passed from the first transistor to the first (very small) integrated circuit. The engineering behind quantum computers is arguably even more challenging than for electronic circuits, at least from today’s perspective. We shouldn’t… Read More
Simulating Quantum Computers. Innovation in Verification
Quantum algorithms must be simulated on classical computers to validate correct behavior, but this looks very different from classical logic simulation. Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and lecturer at Stanford, EE292A) and I continue our… Read More
Quantum Advantage is About the Algorithm, not the Computer
Of course there is a minimum requirement for the computer: enough qubits, fault-tolerant computing, support for hundreds of millions or more computations before a reset, that sort of thing. We’re still on that journey but even after we reach this goal it is important to have a sense of what delivers advantage since the computer … Read More
Quantum Computing Technologies and Challenges
There’s more than one way to build a quantum computer (QC) though it took me a while to find a good reference. I finally settled on Building Quantum Computers: A Practical Introduction. Excellent book but designed only for those who will enjoy lots of quantum math. I’m going to spare you that and instead describe a couple of the more… Read More
Quantum Computing Algorithms and Applications
In an upcoming Innovation blog we’ll get into how quantum computers are programmed. Here I’d like to look more closely at algorithms beyond Grover and Shor, and what practical applications there might be for quantum computing. I also take a quick look at what analysts are saying about potential market size. Even more than in AI, … Read More
An Insight into Building Quantum Computers
Given my physics background I’m ashamed to admit I know very little about quantum computers (QC) though I’m now working to correct that defect. Like many of you I wanted to start with the basics: what are the components and systems in the physical implementation of a quantum “CPU” and how do they map to classical CPUs? I’m finding the… Read More
Think Quantum Computing is Hype? Mastercard Begs to Disagree
Just got an opportunity to write a blog on PQShield, and I’m delighted for several reasons. Happy to work with a company based in Oxford and happy to work on a quantum computing-related topic, which you’ll find I will be getting into more deeply over coming months. (Need a little relief from a constant stream of AI topics.) Also important,… Read More

Can RISC-V Help Recast the DPU Race?
ARM’s Quiet Coup in DPUs
The datacenter is usually framed as a contest between CPUs (x86, ARM, RISC-V) and GPUs (NVIDIA, AMD, custom ASICs). But beneath those high-profile battles, another silent revolution has played out: ARM quietly displaced Intel and AMD in the Data Processing Unit (DPU) market.
DPUs — also called SmartNICs… Read More
