Neustristor: The Computer Chip-Shaped Neutron Source

Posted by in categories: biotech/medical, computing

Sandia National Laboratories distinguished technical staff member Juan Elizondo-Decanini developed a new configuration for neutron generators by turning from conventional cylindrical tubes to the flat geometry of computer chips. The Neutristor is an ultra-compact, disposable, neutron generator 1000 times smaller than the closest competitor. The most practical application, and the most likely to be near-term, would be a tiny medical neutron source implanted close to a tumor that would allow cancer patients to receive a low neutron dose over a long period at home instead of having to be treated at a hospital. Elizondo-Decanini says the technology is ready to be licensed for some commercial applications, but other more complex commercial applications could take five to ten years.

Teleportation is Here, But It’s Not What We Expected

Posted by in categories: humor, particle physics, quantum physics, space travel

In 2005, the obituary of physicist Asher Peres in the magazine Physics Today told us that when a journalist asked him if quantum teleportation could transport a person’s soul as well as their body, the scientist replied: “No, not the body, just the soul.” More than just a simple joke, Peres’ response offers a perfect explanation, encoded in a metaphor, of the reality of a process that we have seen countless times in science fiction. In fact, teleportation does exist, although in the real world it is quite different from the famous “Beam me up, Scotty!” associated with the Star Trek series.

Teleportation in real science began to take shape in 1993 thanks to a theoretical study published by Peres and five other researchers in Physical Review Letters, which laid the foundation for quantum teleportation. Apparently, it was co-author Charles Bennett’s idea to associate the proposed phenomenon with the popular idea of teleportation, but there is an essential difference between fiction and reality: in the latter it’s not matter that travels, but rather information, which transfers properties from the original matter to that of the destination matter.

Quantum teleportation is based on a hypothesis described in 1935 by physicist Albert Einstein and his colleagues Boris Podolsky and Nathan Rosen, known as the EPR paradox. As a consequence of the laws of quantum physics, it was possible to obtain two particles and separate them in space so that they would continue to share their properties, as two halves of a whole. Thus, an action on one of them (on A, or Alice, according to the nomenclature used) would instantaneously have an effect on the other (on B, or Bob). This “spooky action at a distance”, in Einstein’s words, would seem capable of violating the limit of the speed of light.

Black holes: The ultimate quantum computers?

Posted by in categories: computing, cosmology, quantum physics

Circa 2006


By Maggie Mckee

Nearly all of the information that falls into a black hole escapes back out, a controversial new study argues. The work suggests that black holes could one day be used as incredibly accurate quantum computers – if enormous theoretical and practical hurdles can first be overcome.
