Engineers in Australia have have proven, with the highest score ever achieved, that a quantum version of computer code can be written, and manipulated, using two quantum bits in a silicon microchip. The advance removes lingering doubts that such operations can be made reliably enough to allow powerful quantum computers to become a reality.
A review and update of a controversial 20-year-old theory of consciousness published in Elsevier’s Physics of Life Reviews claims that consciousness derives from deeper-level, finer-scale activities inside brain neurons.
Quantum physicists are still very divided on how quantum mechanics is to be interpreted.
Quantum mechanics is real. We wouldn’t have superconductors, lasers, and many forms of computing and cryptography without its microscopically small probabilistic effects. But despite our laboratory certainty, what’s less clear is the role it plays in the fundamental nature of reality. And as a recent survey published by Anton Zeilinger at the University of Vienna has revealed, quantum physicists are still very divided on how it’s to be interpreted.
Matt Joeckel displays a core sample of carbonatite rock containing niobium and rare-earth elements, which was taken from a deposit near Elk Creek, Neb.
The small Nebraska town of Elk Creek (population 112), may not be so small much longer. Reports suggest that the southeastern Nebraska town may be sitting on the world’s largest untapped deposit of “rare earth” minerals, which have proved to be indispensable to a slew of high-tech and military applications such as laser pointers, stadium lighting, electric car batteries and sophisticated missile-guidance systems.
