We are pleased to inform that Quantiki has a new functionality. We introduce Quantiki Video Abstracts - a place where you can upload video abstracts of your papers. If you want to promote your paper just make a short video in which you introduce it and upload it on Quantiki and share it with Quantum Information community. You can also subscribe YouTube channel with Quantiki video abstracts.

Scientists in the UK and US have shown how to increase photovoltaic efficiencies by attaching nanocrystal quantum dots to patterned semiconductor layers. The approach exploits the phenomenon of non-radiative energy transfer and could, say the researchers, lead to a new generation of more efficient solar cells.

Quantum computation was a highly speculative enterprise facing serious technological obstacles until a shy young physicist came along. Dave Bacon tells the story of Alexei Kitaev’s big idea. Read more at PhysicsWorld.

Physicists have teleported quantum information between two atoms separated by a significant distance, for the first time. Until now this feat had only been achieved between photons, and between two nearby atoms through the intermediary action of a third. “Our system has the potential to form the basis for a large-scale ‘quantum repeater’ that can network quantum memories over vast distances” said group leader Christopher Munroe of the University of Maryland.

We're setting up a small Quantiki Workshop!!! If you're interested in getting to know the team, learning more about how Quantiki works, or would like to contribute and work with us - why don't you come along? It is also a good time to tell us how we could improve Quantiki or develope some new ideas and directions for this international non-profit project. Get back to us through the contact form at the top of this page!

Two years ago researchers at Duke University in the US unveiled the first “invisibility cloak” — a device that can make objects vanish from sight, at least when viewed using a narrow band of microwave frequencies. Now, Ulf Leonhardt of St Andrew’s University in the UK and Tomás Tyc of Masaryk University in the Czech Republic have come up with a new way of using mathematics to describe a invisibility cloak (Science DOI: 10.1126/science.1166332).

The entanglement of quantum bits (or qubits) is what should allow quantum computers to perform certain calculations much faster than the computers we use today. But now, physicists in Germany and Canada are saying that most qubits could be “too entangled” to be of any use in quantum computers.

On his blog Bruce Schneier writes "I'm always in favor of security research, and I have enjoyed following the developments in quantum cryptography. But as a product, it has no future. It's not that quantum cryptography might be insecure; it's that cryptography is already sufficiently secure."

Researchers in China and Europe have entangled a record-breaking 10 quantum bits — an important breakthrough in the quest to develop practical quantum computers.

Atoms have been combined for the first time into tightly bound molecules in large numbers at temperatures close to absolute zero.
This is good news for scientists who hope to have greater control over basic chemical reactions and for those who want to build a new
kind of computer, one based on mysterious quantum behavior.
