Australian engineers prove quantum computer coding in silicon now possible

quantumcompu

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.

Recent discovery of quantum vibrations in microtubules inside brain neurons corroborates controversial theory of consciousness

Brain Chemistry

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 agree to disagree about the nature of reality

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.

China’s dominance of vital rare minerals challenged by find in Nebraska mine

rare minerals

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.

New Time Travel Theory Suggests Grandfather Paradox Can Be Avoided

backfuture_l

MIT physicists suggest grandfather paradox can be avoided.

The possibility of going back in time only to kill your ancestors and prevent your own birth has posed a serious problem for potential time travelers, not even considering the technical details of building a time machine. But a new theory proposed by physicists at MIT suggests that this grandfather paradox could be avoided by using quantum teleportation and “post-selecting” what a time traveler could and could not do. So while murdering one’s relatives is unfortunately possible in the present time, such actions would be strictly forbidden if you were to try them during a trip to the past.

Teleportation Achieved Over 10 Miles

teleportation_0129

Quantum teleportation won’t be transporting Kirk and his Away Team to the surface of some distant planet anytime soon, but it has seriously practical applications to communications.

Quantum teleportation has achieved a new milestone or, should we say, a new ten-milestone: scientists have recently had success teleporting information between photons over a free space distance of nearly ten miles, an unprecedented length. The researchers who have accomplished this feat note that this brings us closer to communicating information without needing a traditional signal, and that the ten miles they have reached could span the distance between the surface of the earth and space.

Spacecraft To Test Einstein’s Theory Of Relativity

AlbertEinstein
Does E really equal mc squared?
In what is billed to be the largest scientific instrument ever built, scientists plan to use three spacecraft flying three million miles apart to fire laser beams at each other across the emptiness of space in a bid to finally prove whether a theory proposed by Albert Einstein is correct.

Physicists hope the ambitious mission will allow them to prove the existence of gravitational waves — a phenomenon predicted in Einstein’s famous theory of general relativity and the last piece of his theory still to be proved correct, reports the Telegraph…

Physicist Discovers How to Teleport Energy

Quantum-energy-teleportatio

 

First, they teleported photons, then atoms and ions. Now one physicist has worked out how to do it with energy, a technique that has profound implications for the future of physics.

In 1993, Charlie Bennett at IBM’s Watson Research Center in New York State and a few pals showed how to transmit quantum information from one point in space to another without traversing the intervening space…

Nano-sized “Cargo Ships” Developed To Carry Anti-Cancer Drugs And Markers Through The Body

Nano-sized “Cargo Ships” Developed To Carry Anti-Cancer Drugs And Markers Through The Body 

 The nanometer-sized cargo ships look individually like a chocolate-covered nut cluster, in which a biocompatible lipid forms the chocolate shell and magnetic nanoparticles, quantum dots and the drug doxorubicin are the nuts.

Scientists have developed nanometer-sized ‘cargo ships’ that can sail throughout the body via the bloodstream without immediate detection from the body’s immune radar system and ferry their cargo of anti-cancer drugs and markers into tumors that might otherwise go untreated or undetected.
