Researchers have succeeded in building diodes that manipulate heat, which paves the way for thermal transistors and logic. Lei Wang and Baowen Li describe the emerging field of “phononics”.

MagiQ Technologies, Inc., the quantum information processing (QIP) company announced success of their 3 year joint venture program. The Quantum Communications Victoria (QCV) joint venture has produced the world’s first commercial source of single photons (single particles of light), which are a crucial component of quantum communication systems. MagiQ will collaborate in development and will participate in the sales and marketing of these new products.

Imagine two of your friends tell you – independently - about an agreement for a next meeting. Each of them however mentions a different meeting point. How do you find out who is the liar? And how can you finally succeed to meet at least the honest one at the right time and place?

Forty years ago, mathematician Marek Kac asked the theoretical question, "Can one hear the shape of a drum?". Hari Manoharan from Stanford Physics Faculty investigated with his students the drum question in the quantum realm, where it could have an effect on real nano-electronic systems.

Physical Review Letters celebrates its fiftieth anniversary this year. A number of famous PRL papers from the past half century are being made available on the following website.
