Rare earth elements aren't actually that rare - but they certainly are useful. Erbium is used right now in the internet's optical fibre network, and could one day be applied in quantum networks.
Detecting the errors in data is one thing, but correction them is still possible at the quantum computing level.
One of the challenges for quantum computing is knowing how to detect and correct errors that may occur in the data. And we can do that without even knowing what the data says.
From the man who gave away his genome under open consent, to the 'Mathematikado', this episode of the podcast features highlights from the British Science Festival in Brighton.
Looking inside a quantum computer.
As companies make quantum computers available through their cloud services, take a look at what it means for computing to move beyond classical mechanics and into quantum physics.

Quantum computing is being described as "just around the corner". Is it?

Many scientists thought it was impossible, but one team has finally done it. They say operating their quantum computer is just like playing a game of Pacman.

Don't worry, understanding the work is a piece of cake. But it may make you hungry.
A visualisation of simulation data showing light successfully trapped at a standstill.
Freezing light in mid-air isn't just the realm of Star Wars, as new research shows. But what do you do with the light once it's trapped? One option is to use it to develop new forms of computers.
A new type of computer means we'll need a new way to make our data secure.

Much of the current research in quantum computing involves work at close to absolute zero. A simple breakthough with an everyday material could see them work at more acceptable temperatures.
Even talking to a colleague at an academic conference overseas could have harsh ramifications.
Researchers face stiff fines or even jail time if they inadvertently communicate with foreign colleagues about matters deemed to have a military use.
Malcolm Turnbull has now announced his strategy to promote innovation and science in Australia.
Prime Minister Malcolm Turnbull today announced the National Innovation and Science Agenda (NISA). Here's what it means for science, commercialisation and industry in Australia.
Quantum computing may still have the status of a rank outsider, but it's making gains.
Michelle Simmons was honoured for her leadership on research into quantum computing.
From researchers into the future of quantum computing to those working on low cost energy storage or explaining why onions make you cry, all were winners in the annual Eureka Prizes.

A new report on the future of humanity explains what we really need to be worrying about over the next 35 years.
Binary systems are not enough if you want to improve security.
As hackers get more sophisticated in their cyber crime efforts we need to look to new technology to make our systems more secure, and potentially unhackable. So how can quantum physics help?

Physicists often work unusual hours. You will find them running experiments at 4am and 10pm. This is because, so long as the pertinent conditions inside a lab – such as temperature or light level – are…
Let’s take a look back through the past 12 months of quantum physics research.
The past year has provided some of the most interesting developments in quantum mechanics to date. The field is more than 100 years old and has been tested to unimaginable precision, yet some of its most…

A dramatic increase in the amount of time data can be stored on a single atom means silicon could once again play a vital role in the development of super-fast computers. The silicon chip revolutionised…
