JILA solves problem of quantum dot 'blinking'

Scientists at JILA have found one possible way to induce quantum dots to emit photons faster and more consistently, without their characteristic blinking. The advance could make quantum dots more sensitive as fluorescent tags in biomedical tests and single-molecule studies and steadier sources of single photons for quantum encryption.

5. Immune cell communication key to hunting viruses, Jefferson immunologists show
   10-25-2006 · EurekAlert!
   Immunologists have used nanotechnology to create a novel "biosensor" to solve in part a perplexing problem in immunology: how the immune system's killer T-cells hunt down invading viruses. They have found that surprisingly little virus can turn on killer T-cells, thanks to some complicated communication among "antigen presenting" proteins that recognize and attach to the virus, making it visible to the immune system. Presenting proteins cooperate, spreading a signal among receptors and boosting T-cell response.

7. Entanglement Unties A Tough Quantum Computing Problem
   09-30-2006 · ScienceDaily
   Error correction coding is a fundamental process that underlies all of information science, but the task of adapting classical codes to quantum computing has long bumped up against what seemed to be a fundamental limitation. But a new approach by three theorists working at the USC Viterbi School of Engineering dramatically changes the rules of the game. Adding entangled photons as part of the message stream, they report in Science, opens the door to use of the entire error coding playbook.
