Scientists take a major leap toward a ‘perfect’ quantum metamaterial

Posted by in categories: electronics, nanotechnology, particle physics, quantum physics

Scientists have devised a way to build a “quantum metamaterial” — an engineered material with exotic properties not found in nature — using ultracold atoms trapped in an artificial crystal composed of light. The theoretical work represents a step toward manipulating atoms to transmit information, perform complex simulations or function as powerful sensors.

The research team, led by scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley, proposes the use of an accordion-like atomic framework, or “lattice” structure, made with laser light to trap atoms in regularly spaced nanoscale pockets. Such a light-based structure, which has patterned features that in some ways resemble those of a crystal, is essentially a “perfect” structure — free of the typical defects found in natural materials.

Researchers believe they can pinpoint the placement of a so-called “probe” atom in this crystal of light, and actively tune its behavior with another type of laser light (near-infrared light) to make the atom cough up some of its energy on demand in the form of a particle of light, or photon.

New State of Water: Strange 6-Sided Molecule Found

Posted by in categories: particle physics, quantum physics

A strange new behavior of water molecules has been observed inside crystals of beryl, a type of emerald, caused by bizarre quantum-mechanical effects that let the water molecules face six different directions at the same time.

Under normal conditions, the two hydrogen atoms in each water molecule are arranged around the oxygen atom in an open “V” shape, sometimes compared to a boomerang or Mickey Mouse ears.

New tattoo ink disappears in a year, can be removed on demand

Posted by in category: particle physics

Anyone who has ever gotten, or even thought about getting a tattoo had heard a snarky warning from others about how they’re forever. Well, maybe they aren’t. A company called Ephemeral has designed a two-part system for tattoos that last about a year. It’d probably be a smart move for people who have trouble with commitment.

Traditional tattoos are permanent because the ink particles embedded in the skin are too large for the immune system to clear. Existing methods of tattoo removal with lasers essentially break the particles down until they can be easily cleared. Of course, it really, really hurts. Ephemeral has engineered a two-part system consisting of dye molecules encapsulated in a protective structure and a removal solution.

The protective coating of the dye molecules is engineered to last about one year, at which time it starts breaking down. The tattoo will begin fading rapidly at that point, though it’s not clear how long it will take to fully disappear. The removal solution can be added to the skin at any time by a tattoo machine over top of the Ephemeral tattoo to instantly break down the coating and “erase” parts or all of a tattoo.

Researchers Find Unexpected Magnetic Effect

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

I reported on this finding which the National Labs in Oak Ridge TN published yesterday. This is MIT’s own report on the research and discovery of new material called bismuth selenide (Bi2Se3) with an ultrathin layer of a magnetic material, europium sulfide (EuS). I know that is a mouth full. However, the end result will be that it could lead to a new generation of electronics, spintronics, or quantum computing devices. Definitely a big move forward in bridging QC into all things that use daily.


A new and unexpected magnetic effect has taken researchers by surprise, and could open up a new pathway to advanced electronic devices and even robust quantum computer architecture.

The finding is based on a family of materials called topological insulators (TIs) that has drawn much interest in recent years. The novel electronic properties of TIs might ultimately lead to new generations of electronic, spintronic, or quantum computing devices. The materials behave like ordinary insulators throughout their interiors, blocking electrons from flowing, but their outermost surfaces are nearly perfect conductors, allowing electrons to move freely. The confinement of electrons to this vanishingly thin surface makes then behave in unique ways.

But harnessing the materials’ promise still faces numerous obstacles, one of which is to find a way of combining a TI with a material that has controllable magnetic properties. Now, researchers at MIT and elsewhere say they have found a way to overcome that hurdle.

First single-enzyme method to produce quantum dots revealed

Posted by in categories: engineering, particle physics, quantum physics, solar power, sustainability

Creating Q-Dots/ QDs (Acronym seems to depend on which reference book, article that you read) more cheaply and efficiently too.


Quantum dots (QDs) are semiconducting nanocrystals prized for their optical and electronic properties. The brilliant, pure colors produced by QDs when stimulated with ultraviolet light are ideal for use in flat screen displays, medical imaging devices, solar panels and LEDs. One obstacle to mass production and widespread use of these wonder particles is the difficulty and expense associated with current chemical manufacturing methods that often requiring heat, high pressure and toxic solvents.

But now three Lehigh University engineers have successfully demonstrated the first precisely controlled, biological way to manufacture quantum dots using a single-enzyme, paving the way for a significantly quicker, cheaper and greener production method. Their work was recently featured in an article in The New York Times called “A curious tale of quantum dots.”

Researchers Making Progress With Quantum Computing

Posted by in categories: computing, governance, government, internet, particle physics, quantum physics

I personally can confirm that QC is not being worked on and advance by just a couple groups such as D-Wave and IBM. The questions/bumps in the road that we will all face is threefold:

1) how do we standardize the QC? right now (like most innovation) is done in siloes and limited cross-collaboration across government, labs & universities, and commercial companies. 2) governance and compliance; how will these need to change across multiple areas 3) id & mitigate all impacts instead of after deployment (don’t be reactive) because we will not have that luxury due to hackers.


There is a temptation to lump quantum computing in with technologies such as fusion power in the sense that both have been proposed for decades with the promise of tremendous leaps in performance.

Neutrons tap into magnetism in topological insulators at high temperatures

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

I know that I reported on this a few weeks ago; however, this article shares some additional insights on how this new method will enable more efficient smaller devices including promoting stabilization in Quantum Computing (QC)…


A multi-institutional team of researchers has discovered novel magnetic behavior on the surface of a specialized material that holds promise for smaller, more efficient devices and other advanced technology.

Researchers at the Department of Energy’s Oak Ridge National Laboratory, Massachusetts Institute of Technology and their collaborators used neutron scattering to reveal magnetic moments in hybrid topological insulator (TI) materials at room temperature, hundreds of degrees Fahrenheit warmer than the extreme sub-zero cold where the properties are expected to occur.
