As noted in this post, there has been significant advancements in Quantum Computing hardware over the past year or so and I expect this momentum will continue in 2023. Presently there are QCs with 10s to 100s of qubits, and the coherence, connect-ability and control on these early machines continues to improve. There are various tradeoffs among the QC modalities, summarized in this post.

Quantum Computing “Noise”
There are several significant challenges facing QC makers today, and “noise” is one of the most difficult to overcome.
Why I’m Excited About the Classiq Coding Competition, and Why You Should be Too – Even if You Don’t Understand Quantum Programming
Ultimately, Quantum Computers will only be as valuable and impactful as the programs written for them, so seeing creativity and outside-the-box approaches to challenges with these early, noisy, faulty machines will be quite revealing. The Classiq Coding Competition should bring out this programming creativity.
Quantum Computing is the “Manhattan Project” of This Generation
Those who invest in the winners will enjoy significant outsized financial gains, and those who back the companies that do not survive, will lick their wounds. But as an industry, the race is on, the potential rewards are massive, and the clock is ticking. I sure hope that whoever wins the race uses the power to do good in the world.
Cloud Based Quantum Computer Access – Available Today
People are using actual working Quantum Computers every day. Each of Amazon and Microsoft offer cloud access to several QC hardware systems, while players like Google, IBM, IonQ, Rigetti, Honeywell and others offer direct access to their systems via direct web-based interfaces.
A Quantum Computing Glossary
I’ve curated this list to provide a broad set of definitions that should help frame the Quantum Computing (QC) potential, and for ease of reference as you come across terms where a definitional reminder would be helpful.
Ten Fundamental Facts About Quantum Computing
I’ve covered some key aspects of Quantum Computing in prior posts and thought it would be helpful to synthesize and consolidate some of the fundamental properties of Quantum Computing to provide a bigger picture of the promise and potential of the industry
Quantinuum – Company Evaluation
Computing (CQC) reached an agreement to be acquired by Honeywell for $300m, representing a $545m post-money valuation. Honeywell merged CQC with its Honeywell Quantum Solutions (HQS) division and in November of 2021, spun out the combined businesses into a new stand-alone company called “Quantinuum”.
Quantum Supremacy vs. Quantum Advantage – and how do we measure these things?
compute in seconds what would take the largest and most advanced supercomputers thousands of years, thereby achieving a milestone referred to as “quantum supremacy” for the first time.
Qubits: A Primer
A high-level overview of various types of qubits. The good news is that many entities have created, manipulated and measured qubits and often there has been success in controlling them into superpositions and in entangling a limited but growing number of qubits at a time. For now, this is the NISQ landscape.
