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”
