Stupid Qubit 002: Will Britain be first to build a really useful quantum computer?

Stupid Qubit – Quantum Computing for the Clueless/002

A Brexit special¹ of sorts, as we find out about NQIT, the UK’s Government-supported effort to create a quantum computer – specifically, how they’re hoping to make world-beating machines out of ions levitating in a vacuum. We speak to Star Trek fan Professor Winfried Hensinger at the University of Sussex about his proposed warp-speed machine, as well as Professor Simon Benjamin and Dr Vera Schäfer at the University of Oxford. They’re well under way with the UK’s Q20:20 engine, a near-term machine that aims to connect hundreds of qubits using particles of light.

We also find out why Microsoft wants to tie knots in spacetime with its topological qubits and what a no-deal Brexit could mean for our quantum ambitions [spoiler: it’s not good].

Stupid Qubit 001: What the photonic muck is a quantum computer?

Stupid Qubit – Quantum Computing for the Clueless/001

All over the world, scientists are busy trying to build quantum computers. What the photonic muck is a quantum computer? And why do you need dental floss to make one? How come it looks like a steampunk chandelier? And sounds like an armoured Morris dancer on a punctured spacehopper? Do they really work in parallel universes? And what’s all this about quantum supremacy? Does it mean we’ll soon have to submit to an army of quantum robot overlords?

In this episode, we answer all these questions and more with the help of top quantum physicists including Dr Jerry Chow of IBM, Professor John Martinis of Google and Professor Simon Benjamin of Oxford University.

And we drop in on The Pub Landlord, Al Murray, to see if he has any pressing questions about this exciting new technology…

We hope you enjoyed our first full episode and are now feeling a little less clueless about quantum computing. If so, you might want to learn a bit more about the people and technologies we introduced this time. So, here are some handy links to the quantum scientists, technologists and other stuff we talked about. We still have loads to cover (we’ve not even started on how you program these machines and what they can do today) so stay tuned for episode 2 – sometime in the autumn (we hope).

Clip of Feynman saying nobody understands quantum  physics, plus his famous 1964 Cornell Messenger lectures introducing the key concepts in detail and proving that he, for one, did. They get fairly technical  as you get into the meat of them, but the intro’s fairly accessible – he was a wonderful explainer and populariser of the  field, as these lectures (as well as this classic BBC Horizon programme) show.

And if Feynman’s lectures sound a bit too scary, why not start with this book instead.

Stupid Qubit Episode 0 – Preview

Welcome to Stupid Qubit – Quantum Computing for the Clueless. (Which, as far as quantum computing goes, is pretty much everyone.) Don’t worry – we’re here to make it all crystal clear. Although the crystal might exist in multiple dimensions. Or something. Anyway, here’s a preview of our podcast, coming this summer.

Quantum computing for the clueless

COMING SOON… “Stupid Qubit – Quantum Computing for the Clueless”

An irreverent podcast demystifying current developments in quantum computing for a curious but confused general audience. Presenters Jim & Stu quiz luminaries in the field and attempt to find the answer to questions such as:

• WTF is a quantum computer and how do you build one?
• How do you program one and will they run games in parallel universes?
• When will we get our self-aware, matter-manipulating quantum phones?
