Experimental research on physics and hardware for quantum information processing
[Keio Spintronics Network - Tarucha-Oiwa Laboratory , University of Tokyo] Tokyo University’s Tarucha-Oiwa Laboratory is doing experimental research on physics and hardware for quantum information processing, which utilizes electron transport, spin correlation, and spin in low-dimensional electron systems. The laboratory is looking at electron systems in one and zero dimensions, which can be achieved through semiconductor microfabrication. The researchers study the fundamental physics of many-body effects in artificial atoms and molecules, spin phenomena in strong magnetic fields, the effects of conduction phenomena on electron and nuclear spin, electronic properties in one-dimensional Tomonaga-Luttinger liquids, and spin quantum computing. In addition, the Lab is developing a method of observing state density directly, using a surface-sensitive scanning probe. “In our Lab, the main theme is how to precisely control, investigate, and utilize the quantum mechanical properties of the most basic particles in semiconductors — the atoms. We started this research about 15 years ago. At that time, when we fabricated small structures called quantum dots, we were the first in the world to find out experimentally how to confine electrons in quantum dots, investigate their properties, and control their states.” When electrons are injected one by one into artificial atoms, they occupy orbits, due to the quantum confinement effect, and take on energy levels, like those in real atoms …

1952 newsreel- latest futuristic and experimental aircraft
– Bill Horton’s “wingless airplane”. Bill entered into a partnership with Howard Hughes, and legal wrangling from that (still ongoing!) stopped all development of this plane. — “Sky Baby” the world’s smallest homebuilt biplane, 1952. Made it in the “Guinness Book of World Records”, but not practical for the homebuilt market. Designer Ray Stits donated it to the National Air and Space Museum. — the Fulton Airphibian, the first roadable aircraft (designed to be used as a car or an airplane) to be certificated by the Civil Aviation Administration. — XH-17 “Flying Crane”, by Hughes aircraft. It still holds the record for the largest flying rotor system that ever flew. But was not practical for production. go here to see piece on the Sky Baby: www.airventuremuseum.org go here to see an article on Horton’s “wingless airplane”: home.att.net go here to view article on the Airphibian: www.nasm.si.edu go here to read about the XH-17 “Flying Crane”: avia.russian.ee
