An atomic clock that uses an aluminium atom to apply the logic of computers to the peculiarities of the quantum world now rivals the world's most accurate clock, based on a single mercury atom. Both clocks are at least 10 times more accurate than the current U.S. time standard.

Recently, quantum computing has been heralded as the new cool kid on the block. The point of quantum computing is that, during a calculation, the bits (called qubits) that are being manipulated are never in a definite one or zero state. Instead, they can be thought of as being both a one and a zero simultaneously, which allows a quantum computer to explore many solutions at the same time. The upshot is that, for a limited set of problems, quantum computers may offer a substantial speed up over normal computers.

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.
