- Birth, life and death of a photon
- Two days ago, I told you that German physicists had built a single-photon server. But French researchers also have used ultra cold atoms of rubidium to record the full life of a photon. This was one of Einsteins dreams, but it was thought as an impossible one before. In fact,...

- A single-photon server
- A team of German physicists at the Max Planck Institute of Quantum Optics has built a single-photon server with just one atom. Theyve trapped ultra cold atoms of rubidium in a vacuum chamber and applied laser pulses from one side. The generated photons were of high quality, meaning their energy...

- Detecting single photons
- What do you do when you need to transmit a signal over a long distance, from Saturn, say, and you're low on power? Until now, you turned the bandwidth way down, but new single-photon detectors could change that. Technology Review has an interview with Karl Berggren, an electrical engineering...

- Looking inside your brain... without hurting you
- Researchers at Stanford University have developed a portable device that captures pictures beneath the living brain's surface with minimal invasive effects. This new 3.9 gram two-photon fluorescence microendoscope can fit in the palm of your hand. It combines optical and mechanical techniques to image brain cells up to a millimeter...

- Shooting movies of molecules
- Scientists at the U.S. Department of Energy's DOE Argonne National Laboratory have developed techniques for creating movies of biological and chemical molecules. It has been done before for crystalline structures of salt or metals, but organic molecules are more complex, and more difficult to catch. Until now, researchers had to...

- A new way to improve computer graphics
- Computer scientists at the University of California in San Diego UCSD have developed a fog and smoke machine for computer graphics which dramatically cuts computing costs for generating bright images. They've used 'photon mapping' algorithms, a subset of the more computationally intensive ray tracing algorithms -- and with better results....

- A single-photon channel to space
- According to the Institute of Physics IOP, European researchers have successfully identified individual returning photons from space 'after firing and reflecting them off of a space satellite in orbit almost 1,500 kilometers above the earth.' This experiment could lead to a global quantum-encrypted communications network in the future. In other...

- Lensless camera for nanoscale imaging
- Australian and U.S. scientists have developed a lensless camera which uses X-rays to view nanoscale materials and biological specimens. As says one researcher, 'there is no lens involved at all; instead, a computer uses sophisticated algorithms to reconstruct the image.' Future microscopes equipped with these lensless cameras could be used...
