Transferring quantum information using sound

Quantum physics has led to new types of sensors, secure data transmission methods and researchers are working toward computers. However, the main obstacle is finding the right way to couple and precisely control a sufficient ...

Scientists use DNA to assemble a transistor from graphene

(Phys.org) —Graphene is a sheet of carbon atoms arrayed in a honeycomb pattern, just a single atom thick. It could be a better semiconductor than silicon – if we could fashion it into ribbons 20 to 50 atoms wide. Could ...

Physicists create artificial 'graphene'

An international group of physicists led by the University of Arkansas has created an artificial material with a structure comparable to graphene.

IBM Scientists Demonstrate World's Fastest Graphene Transistor

(PhysOrg.com) -- In a just-published paper in the magazine Science, IBM researchers demonstrated a radio-frequency graphene transistor with the highest cut-off frequency achieved so far for any graphene device - 100 billion ...

Atom Pinhole Camera Acts as a Shrinking Copy Machine

(PhysOrg.com) -- In 1983, Richard Feynman proposed the idea of a machine that could create smaller scale replicas of itself. Today, such a system is still a challenge, but a machine that can produce nanometer-sized copies ...
