Last day of the Summer Science Exhibition
Today is the last day of the Summer Science Exhibition. Our scientists are waiting to meet you and answer your questions about how we can use quantum physics in information technology. Learn how quantum teleportation works, see our secure communication system, look at our quantum devices and test yourself against our single photon detector.
The exhibition is open until 6pm this evening with last entry at 5:30pm.
The Quantum Asteroids game developed at the Royal Society Game Jam is now available to play online though the above page. Try entangling spaceships and teleporting while shooting as many asteroids as you can. Don't forget to go back to the Royal Society site to vote for Quantum Asteroids if you enjoy.
The game will also be available to play within the Royal Society during the Summer Science Exhibition.
Our researchers Sokratis, Jonas and Branislav were in Toulouse, France, for the International Conference on Spin-Optronics, organised by the Marie-Curie ITN SPIN-OPTRONICS European network.
Networks help scientists come together to collaborate and share ideas. They also enable the training of young researchers – often outside the country in which they grew up.
We have been to another conference and this time we went overseas to beautiful California! It was time for CLEO 2013, short for "Conference on Lasers and Electro-Optics". The conference was held in San Jose, which is about 50 miles South East of San Francisco in the Silicon Valley. We sent one of our researchers, Bernd Fröhlich, and one of our PhD students, Ketaki Patel to give a presentation about our work on Quantum Key Distribution. Giving presentations about your work as a researcher is an essential part of being a scientist. Conferences allow you to meet other scientists working on similar topics and to present and discuss your latest results.
It’s been disco time all week in one researcher’s office. We’re not saying what they might be for yet but these flashing LED strips are being auditioned for an appearance on our stand. Watch this colourful space...
Game Jam gets quantum
We contributed a little quantum spookiness to the Game Jam at the Royal Society. Mark Stevenson who works with entangled photons from an electrically driven source went along to work with a team of coders and artists on a game that we hope will be an homage to asteroids and teleportation.
Game Jam team with our scientist Mark in the centre. Starting from just a concept in the morning the team engaged in an intense hour of ideas exchange to flesh out a few different ideas. Things progressed rapidly with artwork for spaceships, asteroids and shooting all making an early appearance and later in the day there were reports of spaceships being observed teleporting around. Mark was working on the game with a great team of developers from Bossa Studios. The studio won the award for best online browser game at the GAME British Academy Video Games Awards in 2012 for their game Monstermind so we are in great hands. By the end of the marathon 12 hour jam they had the game up and running. Further development is underway and you will be able to play the game on The Royal Society's website later in June along with games from 4 other exhibits. It will also be available to play at a location within the Royal Society during the exhibition and you will be able to vote for your favourite game. In the arcade classic Asteroids, the teleportation capability was purely science fiction as quantum teleportation was yet to be invented. In quantum asteroids, we take elements from real quantum teleportation and exaggerate them, just for fun. The game will be ready later this month, when we invite you to create entanglement with your “tangle torpedoes” and destroy yourself to teleport and survive….

CLEO Europe / IQEC 2013
We were in Munich, Germany last week for IQEC 2013, the International Quantum Electronics Conference that runs alongside CLEO Europe and the World of Photonics Congress.
Researcher Dave Ellis was talking about an on demand single photon-driven controlled-NOT gate. This is an important building block for making a quantum computer. It acts on two quantum bits (qubits) and performs a NOT operation on one qubit when the control qubit has the value of “1”. In the implementation Dave described, the qubits are each single photons of light that are sent through a waveguide circuit defined on the top of a semiconductor wafer. The photons are confined within the waveguides and follow their paths through the circuit. The photons interact at number of beamsplitters within the circuit to achieve the desired logical result.
Also at the conference was Jonas Nilsson who presented a postdeadline paper on quantum teleportation using a light emitting diode (LED). Here a pair of photons is created by a special LED that is able to impose a very deep connection between them that we call entanglement. This entanglement survives as the photons move away from each other and we have used the photons in a teleporter. This is one of the most perplexing parts of quantum theory but it’s also tremendously useful as it allows quantum information to be transferred without its physical movement through space.

The Quantum Revolution is coming
We are excited to be bringing the Quantum Revolution to the Summer Science Exhibition at the Royal Society in July.
In the 20th century it was discovered that everything in the universe is made of particles or “quanta”. This sounds simple at first but the idea turned out to be utterly bewildering. Everyday experience of light suggested it is a wave rather than a stream of particles and when people started to look at matter on a small scale they realised that small particles exhibit wave-like properties. From there things only got stranger.
Our exhibit will look at how we are starting to make use of quantum weirdness and to apply it to information technology. Quantum processes offer a radically different way of handling information that will transform some IT applications as well as creating the scope for unique new inventions.
The exhibition is open to the public from Tuesday 2nd July to Sunday 7th so please come along and see us and the demonstrations we will be bringing to London. If you can’t make it we will be posting more information online so follow us and get ready for the Quantum Revolution.
