A new spin on superconductivity: Harvard physicists pass spin information through a superconductor
Posted by Karen Hurst in categories: nanotechnology, quantum physics, supercomputing
New method for information storage via QC uncovered.
Abstract: Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have made a discovery that could lay the foundation for quantum superconducting devices. Their breakthrough solves one the main challenges to quantum computing: how to transmit spin information through superconducting materials.
Every electronic device — from a supercomputer to a dishwasher — works by controlling the flow of charged electrons. But electrons can carry so much more information than just charge; electrons also spin, like a gyroscope on axis.

Diamonds aren’t forever: Sandia, Harvard team create first quantum computer bridge
Posted by Karen Hurst in categories: 3D printing, computing, nanotechnology, quantum physics
Another article on the QC advancement; however, as I told folks synthetic diamonds are key plus the crystalized formation are proven to be very useful not only in QC processing; but also for the light-based (Quantum) networking. I see this only the beginning (as we have seen with Synthetic DNA data storage) for synthetic gem crystalize formations in their usage in technology. Hoping folks are checking out the 3D Printers creating these synthetics because we truly are on the path of seeing our world transform to new levels never imagined.
Abstract: By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
“People have already built small quantum computers,” says Sandia researcher Ryan Camacho. “Maybe the first useful one won’t be a single giant quantum computer but a connected cluster of small ones.”

Berkeley Lab announces first transistor with a working 1-nanometer gate
Posted by Sean Brazell in categories: computing, nanotechnology, quantum physics
Breaks through the 5-nanometer quantum tunneling threshold; may allow for Moore’s law to continue…
The first transistor with a working 1-nanometer (nm) gate has been created by a team led by Lawrence Berkeley National Laboratory (Berkeley Lab) scientists. Until now, a transistor gate size less than 5 nanometers has been considered impossible because of quantum tunneling effects. (One nanometer is the diameter of a glucose molecule.)

Electron spins talk to each other via a ‘quantum mediator’
Posted by Karen Hurst in categories: computing, nanotechnology, quantum physics
The unparalleled possibilities of quantum computers are currently still limited because information exchange between the bits in such computers is difficult, especially over larger distances. FOM workgroup leader Lieven Vandersypen and his colleagues within the QuTech research centre and the Kavli Institute for Nanosciences (Delft University of Technology) have succeeded for the first time in enabling two non-neighbouring quantum bits in the form of electron spins in semiconductors to communicate with each other. They publish their research on 10 October in Nature Nanotechnology.
Information exchange is something that we scarcely think about these days. People constantly communicate via e-mails, mobile messaging applications and phone calls. Technically, it is the bits in those various devices that talk to each other. “For a normal computer, this poses absolutely no problem,” says professor Lieven Vandersypen. “However, for the quantum computer – which is potentially much faster than the current computers – that information exchange between quantum bits is very complex, especially over long distances.”
Mediating with quantum dots Artist impression of two electron spins that talk to each other via a ‘quantum mediator’. The two electrons are each trapped in a semiconductor nanostructure (quantum dot). The two spins interact, and this interaction is mediated by a third, empty quantum dot in the middle. In the future, coupling over larger distances can be achieved using other objects in between to mediate the interaction. This will allow researchers to create two-dimensional networks of coupled spins, that act as quantum bits in a future quantum computer. Copyright: Tremani/TU Delft.

Nanomachines Score The 2016 Nobel Prize in Chemistry
Posted by Elmar Arunov in categories: chemistry, nanotechnology
In Brief.
- Jean-Pierre Sauvage, Sir Fraser Stoddart and Bernard Feringa will share the prize for their design and synthesis of the ‘world’s smallest machines.’
- The state of molecular machines today is at the same level as that of the electric motor in the 1830’
A trio of European scientists brought home the 2016 Nobel Prize in Chemistry. Jean-Pierre Sauvage, Sir J. Fraser Stoddart and Bernard L. Feringa were awarded 8 million Swedish krona for their work on molecular machines.

Molecular Nanotechnologists win Nobel Prize in Chemistry for developing molecular machines
Posted by Klaus Baldauf in categories: chemistry, nanotechnology
Bernard Feringa was the first person to develop a molecular motor; in 1999 he got a molecular rotor blade to spin continually in the same direction. Using molecular motors, he has rotated a glass cylinder that is 10,000 times bigger than the motor and also designed a nanocar.
A tiny lift, artificial muscles and miniscule motors. The Nobel Prize in Chemistry 2016 is awarded to Jean-Pierre Sauvage, Sir J. Fraser Stoddart and Bernard L. Feringa for their design and production of molecular machines. They have developed molecules with controllable movements, which can perform a task when energy is added.
