Photonic quantum computers: a brighter future than ever
05/13/2013 - 09:38

Harnessing the unique features of the quantum world promises a dramatic speed-up in information processing as compared to the fastest classical machines. Scientists from the Group of Philip Walther from the Faculty of Physics, University of Vienna succeeded in prototyping a new and highly resource efficient model of a quantum computer – the boson sampling computer. The results will be published in the upcoming issue of the renowned scientific journal "Nature Photonics".

New Computational Model Can Predict Breast Cancer Survival
04/18/2013 - 09:14

Columbia Engineering researchers, led by Dimitris Anastassiou, Charles Batchelor Professor in Electrical Engineering and member of the Columbia Initiative in Systems Biology, have developed a new computational model that is highly predictive of breast cancer survival. The team, which won the Sage Bionetworks / DREAM Breast Cancer Prognosis Challenge for this work, published its results—"Development of a Prognostic Model for Breast Cancer Survival in an Open Challenge Environment"—in the April 17 issue of Science Translational Medicine.

New keyboard for touchscreens
04/17/2013 - 10:01

The research team of Antti Oulasvirta at the Max Planck Institute for Informatics has created a new keyboard called KALQ that enables faster thumb-typing on touchscreen devices. They used computational optimization techniques in conjunction with a model of thumb movement to search among millions of potential layouts before identifying one that yields superior performance. A user study confirmed that, after a short amount of practice, users could type 34% faster than they could with a QWERTY layout.

Researchers evaluate Bose-Einstein condensates for communicating among quantum computers
04/11/2013 - 11:47

Quantum computers promise to perform certain types of operations much more quickly than conventional digital computers. But many challenges must be addressed before these ultra-fast machines become available, among them, the loss of order in the systems – a problem known as quantum decoherence – which worsens as the number of bits in a quantum computer increases.
