Unearthing a New Quantum State of Matter: Quantum Physics Discoveries Could Change Face of Technology .

From that research, a surprising topological semimetal has emerged.

"We never expected a result like this based on previous studies," said Liu. "We were surprised to find that such a simple system could reveal itself as a new type of topological state -- an insulator that shares the same properties as a quantum Hall state in solid materials."

Since the discovery of the quantum Hall effect by Klaus Van Klitzing in 1985, researchers like Liu have been particularly interested in studying topological states of matter, that is, properties of space unchanged under continuous deformations or distortions such as bending and stretching. The quantum Hall effect proved that when a magnetic field is applied perpendicular to the direction a current is flowing through a metal, a voltage is developed in the third perpendicular direction. Liu's work has yielded similar yet remarkably different results.

"This new quantum state is very reminiscent of quantum Hall edge states," said Liu. "It shares the same surface appearance, but the mechanism is entirely different: This Hall-like state is driven by interaction, not by an applied magnetic field."

Liu and his collaborators have come up with a specific experimental design of optical lattices and tested the topological semimetal state by loading very cold atoms onto this "checkerboard" lattice. Generally, these tests result in two or more domains with opposite orbital currents; therefore the angular momentum remains at zero. However, in Liu's study, the atoms formed global rotations, which broke time-reversal symmetry: The momentum was higher, and the currents were not opposite.

"By studying these orbital degrees of freedom, we were able to discover liquid matter that had no origins within solid-state electronic materials," said Liu.

Liu says this liquid matter could potentially lead toward topological quantum computers and new quantum devices for topological quantum telecommunication. Next, he and his team plan to measure quantities for a cold-atom system to check these predicted quantum-like properties.

This is very true and going to happen sooner than later.

World had been deliberately kept in dark by controlling the technology, education and research work.

It is dangerous to speak on such issues.

There is no doubt that cutting-edge research (and, increasingly, commercial applications) in quantum mechanics will completely revolutionize technology. It will make current technology look like prehistoric clay tablets.

Just reading some of the research in quantum zeno effects, atomic mirrors, macroscopic quantum entanglement (in diamonds), etc. is absolutely mind blowing...

Note that this research is taking place in the USA at the University of Pittsburgh (my wife's alma mater), and in Germany,with primary funding from the USA Defense Department's ARPA unit.

The movie Matrix had a interesting take on Quantum Physics. But unfortunately people remember it for some action scenes.

Implementing Quantum results for Macroscopic objects are quite difficult...... For example Quantum transportation has been done for a single photon but for any meaningful thing to be transported, it will take at least many many years.....

These researches are being carried out all over the world, so do not fool yourself by your egocentricism.
These researches are carried out by whom?

As a condense matter physics student I think quantum physics is a essential in todays world for future advancements as the laws of the quantum world are vital for day to day stuff like computer chips and phones

topological insulators and quantum phase transitions are still a highly theoretical field of study that has little application to real life. that's because quantum phase transitions are usually only seen at extremely low temperatures and then varying another parameter like magnetic field, which is impractical; superconductors already provide much more "bang for the buck" if you're going to use low temperature materials, and they're not in common use except for highly specialized applications.
