Team adds to quantum computing toolkit with mixed-atom logic operations

Posted by in categories: computing, particle physics, quantum physics

Physicists at the National Institute of Standards and Technology (NIST) have added to their collection of ingredients for future quantum computers by performing logic operations—basic computing steps—with two atoms of different elements. This hybrid design could be an advantage in large computers and networks based on quantum physics.

The NIST experiment, described in the Dec. 17 issue of Nature, manipulated one magnesium and one beryllium ion (charged atom) confined in a custom trap (see photo). The scientists used two sets of laser beams to entangle the two ions—establishing a special quantum link between their properties—and to perform two types of logic operations, a controlled NOT (CNOT) gate and a SWAP gate. The same issue of Nature describes similar work with two forms of performed at the University of Oxford.

“Hybrid quantum computers allow the unique advantages of different types of quantum systems to be exploited together in a single platform,” said lead author Ting Rei Tan. “Many research groups are pursuing this general approach. Each ion species is unique, and certain ones are better suited for certain tasks such as memory storage, while others are more suited to provide interconnects for data transfer between remote systems.”

Enormous Christmas Eve Asteroid Sparks Fears: ‘Potentially Hazardous’ Space Rock Could Cause Earthquakes, Wake Dormant Volcanoes

Posted by in category: space

Merry Christmas, my friends. wink

A massive asteroid flying by Earth on 2015 Christmas Eve has scientists on edge. While NASA is downplaying the threat to human life and property, conspiracy theorists and several experts say space rock 2003 SD220 is larger than believed and has the potential to cause deadly earthquakes and eruptions from dormant volcanoes.

According to a Sun report, the Christmas Eve asteroid is one of at least 10 rocky bodies in space that are considered “potentially hazardous” to Earth. According to an internal report, NASA officials say it measures about 1.5 miles wide and is moving at 5 miles per second.

What do you call a DNA molecule that changes between high and low electrical conductance (amount of current flow)?

Answer: a molecular switch (transistor) for nanoscale computing. That’s what a team of researchers from the University of California, Davis and the University of Washington have documented in a paper published in Nature Communications Dec. 9.

Four Market Forces That Will Shape Robotics Over The Next Year

Posted by in categories: military, robotics/AI

“When will I have a robot that can do my laundry?”

This is the number one question I get from friends and family members, whose expectations are unconstrained by the software and hardware technical realities that make robots tick (washing dishes is a close second by the way).

Since most have been waiting a lifetime for this transformational milestone, I have been promising lately, with muted bravado, that it won’t be too long now.

Our Aging World: The Striking Statistics About Diabetes

Posted by in categories: biotech/medical, life extension

By 2034 the annual cost of diabetes in the US will be comparable to the market capitalization of Google.

Diabetes comes in two main forms, type 1 and type 2. Type 1 diabetes is caused by a failure of the body to produce the hormone insulin that helps sugar molecules to be absorbed by your cells. This type of diabetes is commonly caused by an autoimmune reaction in which the body attacks the pancreas, the gland that produces insulin, and normally occurs during childhood. The second form is when the body becomes insensitive to insulin; the hormone is still there but the cells no longer respond to it. In the Dutch language this form used to be called ‘ouderdomsdiabetes’ meaning ‘diabetes of old age’. This description is no longer accurate as even teenagers have now been diagnosed with it.
