"NANO-CVD: chip-making process tames carbon nanotube growth"
A chemical-vapor deposition technique has been applied to carbon nanotubes to give them unusual electronic properties, according to Ganapathiraman Ramanath here at Rensselaer Polytechnic Institute. The treated nanotubes could be used by chip makers to interconnect single-electron transistors with high-efficiency wires. The group aims to build a nanotube architecture that will exhibit near-superconducting speeds at room temperature, plus the ability to pack devices tighter and control quantum effects.

"CIRCUIT PAINTING: scientist makes photonic circuits with inkjet printer "
A new family of organic polymers demonstrated at the University of Arizona can "paint" computer displays and photocell arrays onto most any surface, and could enable self-contained "computerless" niche devices that are cheaper and more flexible than what's available today.

"ENCRYPTION: scales to fit smaller RF ID tags"
Armed with a simplified mathematical approach to public-key encryption, NTRU Cryptosystems Inc. here is introducing intellectual property that can add security to virtually any circuit. The most recent product based on the approach is a circuit block that can be added to small wireless products such as smart cards and point-of-sale ID tags. NTRU claims the approach is as secure as the popular RSA public-key encryption system but is computationally much simpler.

"QUANTUM COMPUTING: Researchers demo secure storage of quantum data"
With the successful transfer of quantum information encoded in laser beams into a physical system and the subsequent retrieval of that information unaltered, Harvard University researchers have succeeded in bringing practical quantum computers one step closer to reality.
