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.

**The Evolving Quantum Computing Ecosystem**

Quantum Computers will spur many players in its ecosystem, in fact there are already 100’s of players engaged in this space., Some of these participants may carve out significant market positions and value.

## 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.

## Follow the Money…the Quantum Computing Goldrush

amount of funding being dedicated to Quantum Computing on a global basis is staggering. Governments, private companies, venture firms and academic institutions are all committing huge sums of money and resources to this field. While investment flows are no guarantee of future value, there is a broad common theme to push the development of Quantum Computers, and the equivalent of the modern “space race” is garnering growing attention in the media. Given the awesome power, potential and disruption that Quantum Computers can deliver, these trends should not be surprising.

**Quantum Quantum Everywhere**

In this post I will cover some of the near-term use cases for Quantum Computing, but first I want to cover how “Quantum” or, specifically, the quantum mechanics underlying the power of Quantum Computing, is already used in our daily lives, some near term applications where quantum effects are providing powerful new capabilities, and finally, where the power of Quantum Computing will likely have the most impact.

## Quantum Superposition and Entanglement

In prior posts I emphasized the excitement and potential of Quantum Computing, without any reference to the underlying quantum mechanics, but would like to introduce you to some unique quantum properties in this post. While understanding the nature of Quantum Computing is complex and contains many new concepts, a basic understanding of “Superposition” and “Entanglement”Continue reading “Quantum Superposition and Entanglement”

## What is a Computer? – Analog vs Digital vs Quantum

Before we can get into the inner workings of a Quantum Computer, we should make sure we are in alignment on what a computer actually is. At its core, a computer is a machine that is designed to perform prescribed mathematical and logical operations at high speed, and display the results of these operations. GenerallyContinue reading “What is a Computer? – Analog vs Digital vs Quantum”

## Why is Quantum Computing so Exciting and How Can It Be So Powerful?

If you are reading this blog you are likely already familiar with some of the essential features of Quantum Computing like superposition and entanglement. Even if you are not, I will cover some of those details in future posts. For now, I wanted to begin without any physics or linear algebra and instead give youContinue reading “Why is Quantum Computing so Exciting and How Can It Be So Powerful?”

## A little about about me and this website

I remember being intrigued by “computers” as a high school student in the late 70’s. Personal Computers (PC’s) were not yet available, but I bought a Sinclair ZX80 at Radio Shack in 1980 and tried to teach myself how to program it. I was awed by the potential, and fascinated by the details, and wroteContinue reading “A little about about me and this website”
