Quantum processor for single photons

"Nothing is impossible!" In line with this motto, physicists from the Quantum Dynamics Division of Professor Gerhard Rempe (director at the Max Planck Institute of Quantum Optics) managed to realise a quantum logic gate in ...

Why megaprojects often have megapitfalls

While the new Bay Bridge is finally functional, it stands more as a symbol of dysfunction than anything else. From the start it seemed born under a bad sign, down since it began to crawl—like, if it wasn't for bad luck, ...

Genetic algorithms can improve quantum simulations

(Phys.org)—Inspired by natural selection and the concept of "survival of the fittest," genetic algorithms are flexible optimization techniques that can find the best solution to a problem by repeatedly selecting for and ...

Solar-plane pilots say trip was also test of human endurance

The two Swiss pilots taking turns to fly a solar-powered airplane around the world said Sunday the endeavor is not only a demonstration of the importance of renewable energy but also of the many challenges the human body ...

Solar plane pilot hopes to link to Silicon Valley's spirit

The pilot of a solar-powered airplane on an around-the-world journey said Saturday that stopping in California's Silicon Valley will help link the daring project to the pioneering spirit of the area.

A programming language for living cells

MIT biological engineers have created a programming language that allows them to rapidly design complex, DNA-encoded circuits that give new functions to living cells.

Physicists demonstrate a quantum Fredkin gate

Researchers from Griffith University and the University of Queensland have overcome one of the key challenges to quantum computing by simplifying a complex quantum logic operation. They demonstrated this by experimentally ...
