New single-photon microwave source developed
Posted by Karen Hurst in categories: computing, quantum physics
A collaboration including researchers at the National Physical Laboratory (NPL) has developed a tuneable, high-efficiency, single-photon microwave source. The technology has great potential for applications in quantum computing and quantum information technology, as well as in studying the fundamental reactions between light and matter in quantum circuits.
Circuits which produce single photons are a vital component in quantum computers. They usually consist of a quantum bit or ‘qubit’, coupled to a resonance circuit. The resonant circuit limits the photon output to specific frequencies depending on the design of the circuit.

Synopsis: Tickled by a Wigner Crystal
Posted by Karen Hurst in category: quantum physics
Nice synopsis.
The lattice symmetry of a quantum Wigner crystal is deduced from its effect on quantized states in a nearby sheet of electrons.
Left to their own devices, electrons confined to a sheet can crystallize into an ordered array at low temperatures because of their mutual repulsion. Physicists have observed a classical version of this “Wigner crystal” in electrons floating on liquid helium and a quantum variety in electrons trapped at a semiconductor interface. But the lattice geometry of electrons in the latter has been tough to glean. A team led by Mansour Shayegan at Princeton University, New Jersey, obtained this information using a new technique, possibly providing a way to test the many-body theories that predict Wigner crystallization.

China’s Race to Space Domination: To Try to Gain an Edge Here on Earth, China is Pushing Ahead in Space
Posted by Karen Hurst in categories: energy, engineering, quantum physics, robotics/AI, space
More on China’s race on Space. Last Tuesday, China launched the 1st Quantum Satellite. In 2017, China is planning to be the dominant force in mining of Space. First stop — mining the dark side of the moon. Given China’s own history with environmental pollution plus mining’s damaging effects to the environment when not properly managed; etc. one must ponder how will space and Earth itself be impacted by such mining.
Before this decade is out, humanity will go where it’s never gone before: the far side of the moon. This dark side — forever facing away from us — has long been a mystery. No human-made object has ever touched its surface. The mission will be a marvel of engineering. It will involve a rocket that weighs hundreds of tons (traveling almost 250,000 miles), a robot lander, and an unmanned lunar rover that will use sensors, cameras, and an infrared spectrometer to uncover billion-year-old secrets from the soil. The mission also might scout the moon’s supply of helium-3 — a promising material for fusion energy. And the nation planting its starry flag on this historic trip will be the People’s Republic of China.

Light and matter merge in quantum coupling
Posted by Andreas Matt in categories: computing, quantum physics
Where light and matter intersect, the world illuminates. Where light and matter interact so strongly that they become one, they illuminate a world of new physics, according to Rice University scientists.
Rice physicists are closing in on a way to create a new condensed matter state in which all the electrons in a material act as one by manipulating them with light and a magnetic field. The effect made possible by a custom-built, finely tuned cavity for terahertz radiation shows one of the strongest light-matter coupling phenomena ever observed.
The work by Rice physicist Junichiro Kono and his colleagues is described in Nature Physics. It could help advance technologies like quantum computers and communications by revealing new phenomena to those who study cavity quantum electrodynamics and condensed matter physics, Kono said.
