Physicists Achieve Quantum Teleportation of Photon Over 25 Kilometers For the first time, a team of physicists have successfully teleported a quantum state of a photon to a crystal over 25 kilometers away through a fiber optic cable. This effectively showed that the photon’s quantum state, not its composition, is important to the teleportation process. The team was led by Nicolas Gisin of the University of Geneva and the results were published in the journal Nature Photonics. With this new paper, Gisin’s team has successfully squashed the previous record they set a decade ago by teleporting a quantum state of a proton 6 kilometers. The quantum state of the photon is able to preserve information under extreme conditions, including the difference between traveling as light or becoming stored in the crystal like matter. The photon’s state acts as information that can be teleported along great distances using the optical fiber, and can be stored within the crystal.

Teaching with TLC: 10 ways to make physical science FUN! This month we've been completing lots of physical science lessons that my kids do not want to put down. I just love it when they are hooked on learning! My kids have been learning all about simple machines, matter, and electricity from the best science teachers at the Edison Home. What better place to learn about science than Edison's home! A big thank you to the wild wizards there! They did a super job setting the stage for further science lessons. Graphing Motion Ten problems will be generated in a random manner. Your task involves interpreting a graph and identifying the motion parameters which would be required to duplicate the graph. Directions: Analyze the given graph and determine the initial velocity, final time for each interval and acceleration during each interval. Enter this information into the designated fields; use the TAB key to tab from field to field. When you have entered information into all the fields, click on the Check Answer button at the bottom of the screen.
Inspire Her Mind Science There’s a young 4-year old girl shuffling through a chest full of various dress-up clothes. The copy asks: Does dress-up determine her future? Scroll to the left, and the girl picks up a princess dress from the chest.
