Where Did the Universe Come From? and Other Cosmic Questions is a book I wrote with my academic colleague and friend Geraint Lewis. Geraint is a gifted scientific communicator and, if you aren’t already from Wales, you’ll love his Welsh accent. Geraint is also an astrophysicist, whereas I am a quantum physicist. In the worldContinue reading “Where did the universe come from? And other cosmic questions!”

## The Quantum In You

Roses are red.Violets are blue.My heart loves all,The quantum in you. Nitrogen, calcium,And phosphorus.There’s so much in common,Between two of us. Hydrogen, carbon,And oxygen.There’s a lot going on,Under your skin. From your head to your toes,You’re made of this stuff.To look on the outside,Is never enough. Inside and out,Atoms and space,To think of them all,MakesContinue reading “The Quantum In You”

## Here’s what an immortal Italian plumber can teach you about quantum physics

Or, what would Quantum Mario Bros. look like?

## Introduction to Quantum Computing

During the Spring (southern hemisphere) of 2020 I’m teaching Introduction to Quantum Computing. In these Covid-19 times, the class is completely online. Hence a perfect time to flip the classroom. The lecture notes are being blogged over on Medium: https://link.medium.com/3yBRyT6eZ8

## Quantum Entanglement for Toddlers

I wrote a book a while back called Quantum Entanglement for Babies. But, now all those babies are grown into toddlers! I’ve been asked what is next on their journey to quantum enlightenment. Surely they have iPads now and know how to scroll, and so I give you Quantum Entanglement for Toddlers, the infographic! BelowContinue reading “Quantum Entanglement for Toddlers”

## Entry Points for Learning Quantum Computing

Desiree Vogt-Lee maintains a list of quantum computing resources called Awesome Quantum Computing. It is indeed awesome and comprehensive. Here I am looking to answer the question where do I start with quantum computing? with a more concise list of my current favourite entry points. But, before we get started, a general piece of adviceContinue reading “Entry Points for Learning Quantum Computing”

## When will we have a quantum computer? Never, with that attitude

We are quantum drunks under the lamp post—we are only looking at stuff that we can shine photons on.

## The minimal effort explanation of quantum computing

Quantum computing is really complicated, right? Far more complicated than conventional computing, surely. But, wait. Do I even understand how my laptop works? Probably not. I don’t even understand how a doorknob works. I mean, I can use a doorknob. But don’t ask me to design one, or even draw a picture of the innerContinue reading “The minimal effort explanation of quantum computing”

## The real magic of quantum computing

By now you have read many articles on quantum computing. Congratulations. You know nothing about quantum computing.
