Simple Mod Can Keep Quantum States 10,000 Times Longer

Technological advancements have allowed physicists to manipulate and study quantum particles, their states, and their interactions. However, they still need to figure out how to keep quantum systems from decaying long enough to practically run computations and transfer information—and a simple solution might just solve the problem

Yale Creates Error-Correcting Cat for Quantum Computers

Physicists from Yale University have developed an "error-correcting cat". This device combines the concept of superposition from the famous Schrödinger's cat experiment, and the ability to fix some of the persisting problems with quantum computation.

VIDEO—Watch How Researchers Tricked Light Into Revealing Its Paradoxical Nature

If you ever thought that you were alone in not understanding how light could both be a particle and a wave, you need not worry because you weren’t. In fact, for the better part of a century since Einstein theorized the dual nature of light, even researchers have had a tough time digesting the out-of-the-box quantum physics that this notion required to be true. Many researchers simply assumed that since the math checked out, and Einstein being the brilliant genius that he was, that the theory was right. But now, with some clever experimental design and a super-powered electron microscope, researchers are putting the doubts to rest and proving Einstein’s theory once and for all.

The Light Theory—How Researchers Are Proving Einstein Right With a Snapshot

As one of these few disciplines, quantum physics falls into a realm of science where well-documented and highly regarded theories take precedence. But explaining these theories requires a deep understanding of the underlying science, and devising lab experiments to illustrate them is a near impossible feat. One research team of American and Swiss physicists with the EPFL Labs in Switzerland, however, are doing just that. And equipped with some wire, a laser and quick-capturing electron microscope they’re proving what Einstein theorized was true — light can act as a particle and a wave.

Quantum Computing Laser The Size of A Grain of Rice―Coming To A Screen Near You

A sole grain of rice is anything but filling; it is, however, small. Now, imagine a laser producing electrode that size. It's like something straight out of a low-budget Sci-Fi film. But now it's a reality―a laser of equal size has been created by a few researchers at Princeton University, representing a "quantum" leap in future technology.

The Man Behind the Theorem—CERN Artwork Pays Homage to John Stuart Bell

Coming off the toes of Nov. 10 World Science Day for Peace and Development, established by UNESCO in 2001, CERN announced this week that an exhibition held in Belfast, Ireland may reveal another view of famed physicist John Stewart Bell’s extraordinary career. The exhibition entitled Action at a Distance: The Life and Legacy of John Stuart Bell celebrates the 50th anniversary of Bell’s famous theorem that revolutionized the field of quantum theory, and reveals much more than the numbers and variables in the head of the man.
