67-attosecond extreme ultraviolet laser pulse is the world's shortest
A University of Central Florida research team has created the world's shortest laser pulse and in the process may have given scientists a new tool to watch quantum mechanics in action – something that has ...
Physicists devise means for observing single atom interference over coherence length
A new phase in reading photons: Photodetector beats the quantum limit by a factor of four
A new photodetector can cleanly discriminate among four states, not just the standard two states of binary logic.
World's most powerful X-ray laser creates two-million-degree matter
Researchers working at the SLAC National Accelerator Laboratory have used the world's most powerful X-ray laser to create and probe a two-million-degree piece of matter in a controlled way for the first time. ...
Researchers find retinal rods able to detect photon number distribution
First, fast, and faster
(Phys.org) -- Scientists in PML's Quantum Measurement Division have produced the first superluminal light pulses made by using a technique called four-wave mixing, creating two separate pulses whose peaks ...
New camera system creates high-resolution 3-D images from up to a kilometer away
(Phys.org) —A standard camera takes flat, 2-D pictures. To get 3-D information, such as the distance to a far-away object, scientists can bounce a laser beam off the object and measure how long it takes ...
