 Researchers advance quantum-memory-retention time
Electronics Design, Strategy News - Feb. 5 Researchers at GEORGIA TECH have announced a significant advance in the retention time of multiatom quantum-memory devices—from a previous maximum of 32 Ęsec to 7 msec. The significance of the advance is that, with retention time of milliseconds, a bit in quantum memory now lasts longer than the time it would take a photon to travel through 100 km of optical fiber from one repeater to another in a long-range quantum network. Quantum networks function by distributing entangled quantum qubits between two repeaters, so modifying the qubit on one end modifies it on the other end, as well. (full story)
 A robot ready for the beach
Science Friday (NPR) Sand is difficult terrain for robots to navigate. Looking to lizards
and cockroaches for clues, Daniel Goldman, a physicist at Georgia
Institute of Technology, and his colleagues figured out how to making a
robot that wouldn't be slowed by soft ground. The trick? It's all in
the step. (movie clip | Daniel Goldman )
 Famous black Mathematicians - Wilfrid Gangbo
Algorithmist - Feb. 24 Few accomplishments in academia top Wilfrid Gangbo’s move from Ph.D. to full professor in nine years. Born in Benin, he earned his Ph.D. from the Swiss Federale Institute of Technology. Dr. Gangbo is currently a professor at Georgia Tech. Dr. Gangbo is also the founder of the EcoAfrica project, an association of scientists involved in projects supporting African countries. The EcoAfrica project was founded in 1990 in Switzerland and has organized several workshops in applied mathematics. ( full story )
 Biologists find gene network that gave rise to first tooth
GT Newsroom - Feb. 10 Scientists at Georgia Tech have identified a set
of genes that they believe was responsible for forming the first teeth
in vertebrates. This gene network is believed to have been responsible
for the formation of teeth in the throat of the first jawless fish half
a billion years ago and are still responsible for the development of
teeth in the jaws of all animals today. (full story)
