Keywords: Optics (5940494627).jpg NIST's optics table on a chip is a superconducting circuit on a square sapphire chip about 6 millimeters wide Scientists use the chip to place a single microwave photon in two frequencies or colors at the same time The photon is prepared by an artificial atom small yellow square in the middle of the chip The arrow shape at the lower left connects to a transmission line used to tune the SQUID small black area near the point of the arrow The SQUID couples together two resonant frequencies of the cavity meandering line and the photon oscillates between different superpositions of those frequencies Credit D Schmidt/NIST Disclaimer Any mention of commercial products within NIST web pages is for information only; it does not imply recommendation or endorsement by NIST Use of NIST Information These World Wide Web pages are provided as a public service by the National Institute of Standards and Technology NIST With the exception of material marked as copyrighted information presented on these pages is considered public information and may be distributed or copied Use of appropriate byline/photo/image credits is requested https //www flickr com/photos/usnistgov/5940494627/ Optics 2011-06-16 14 29 https //www flickr com/people/63059536 N06 National Institute of Standards and Technology PD-USGov National Institute of Standards and Technology https //flickr com/photos/63059536 N06/5940494627 2016-09-07 02 32 13 United States Government Work Uncategorized 2016 September 27 |
