I’ve left sunny Stockholm and I’m back at the office in blustery Bristol, but I still have a few good quantum tales to tell from the science-writers’ workshop at NORDITA last week. On Thursday, the main speaker of the day was Raymond Laflamme, who is the current director of the Institute for Quantum Computing at the University of Waterloo in Canada. Laflamme – who kick-started his career working on cosmology at the University of Cambridge in the UK as a student of Stephen Hawking – studies quantum decoherence and how to protect quantum systems from it by applying quantum error-correction codes, as well as using nuclear magnetic resonance (NMR) to develop a scalable method of controlling quantum systems.

“Reality is a concept you can apply to your cats,” says Rainer Kaltenbaek to a room full of journalists and physicists, “so long as you don’t talk to Schrödinger.” Indeed, he warns us to not bother applying reality to anything that exists at the quantum level as we will just end up disappointed.
I am in Stockholm at a workshop for science writers being hosted at the Nordic Institute for Theoretical Physics (NORDITA) and the idea of completely forgetting “reality” is one of the many interesting things I have been pondering. Over the past two days we have discussed Bell’s loopholes, using your bathtub as an analogue laboratory to study black (and white) holes and learned about problems that even the best quantum computers (if they could be built) will not be able to solve.

Most of us can’t get our day started without a fortifying cup of coffee and astronauts are just the same. To help those on the International Space Station meet their caffeine cravings, Italian coffee king Lavazza has designed and built an espresso machine that will work in space! Called “ISSpresso” the machine will be blasted off into space in the possession of astronaut Samantha Cristoforetti, who will also be the first Italian woman in space. You can read all about the ISSpresso and its supreme blends on the Wired website.

It’s the nightmare scenario for any PhD student: losing all those research results that you carefully squirreled away for when you finally sit down to write your thesis. That’s just what happened to biologist Billy Hinchen, who lost four years’ worth of 3D time-lapse videos of developing crustacean embryos when his laptop and back-up drives were stolen. Find out what happened next in “What would happen if you lost all of your research data?” by Julia Giddings at the scientific software firm Digital Science. Hinchen also tells his tale of woe in the video above.

This week the Welsh pop star Charlotte Church (right) has released her latest EP entitled Four. In a conversation with New Scientist, Church explained that the EP’s opening track “Entanglement” was in fact named after the quantum-mechanical phenomenon known affectionately to physicists as “spooky action at a distance”. She has since told BBC Wales that she may well take her interest in science to the next level by studying for a physics degree.
There are of course several really famous people who are more directly connected with physics, having studied the subject in some form before going on to become luminaries in other fields. Examples include the Queen guitar-god Brian May, and arguably the most powerful woman in the world the German chancellor Angela Merkel. But Church is one of a new brigade of celebrities who are discovering the joys of physics after having already reached stardom for other abilities. The armchair psychologist might suggest that learning about the mechanics of the cosmos offers a refreshing alternative to the shallow nature of life that often comes with the celebrity lifestyle, or at least our view of it as presented by the media.
