The iconic MIT home page Spotlight features a daily-changing image and design that focuses on advances in research, technology and education taking place at the Institute. Though some Spotlights do run multiple days - for example Friday's spot usually runs through the weekend, we work very hard to maintain the daily-changing tradition. We've combed our servers and have compiled a digital archive of the Institute home page through the years - well over 2000 images. Enjoy!

Massive entanglementToday’s Spotlight features an animation, by Christine Daniloff/MIT and Jose-Luis Olivares/MIT, of a conceptual image showing a photon traveling through entangled atoms.

Physicists from MIT and the University of Belgrade have developed a new technique that can successfully entangle 3,000 atoms using only a single photon. The results, published today in the journal Nature, represent the largest number of particles that have ever been mutually entangled experimentally.

The researchers say the technique provides a realistic method to generate large ensembles of entangled atoms, which are key components for realizing more-precise atomic clocks.

The MIT home page Spotlight showcases the research, technology and education advances taking place at the Institute every day.

What makes it as a Spotlight image is an editorial decision by the MIT News Office based on factors that include timeliness, promotion of MIT's mission, the balance of interest to both internal and external audiences, and appropriateness.

We do welcome ideas and submissions for spotlights from community members, but please note we are not able to accommodate all requests. We are unable to run event previews or promotions as spotlights; for those looking to promote an event, we are happy to include your listing as an event headline on the homepage (when space is available). For more information, e-mail the spotlight team.

Today’s Spotlight uses a graphic, by Christine Daniloff/MIT News, based on an image supplied by the researchers. The new molecules are known as ‘graphene fragments,’ because they largely consist of flat sheets of carbon (which are attached to zinc atoms). That makes them easier to align during deposition, which could simplify the manufacture of molecular memories.

Moore’s law — the well‑known doubling of computer chips’ computational power every 18 months or so — has been paced by a similarly steady increase in the storage capacity of disk drives. In 1980, a hard drive could store about a half‑megabyte of data in a square inch of disk space; now, manufacturers are closing in on a million megabytes of data per square inch.

An experimental technology called molecular memory, which would store data in individual molecules, promises another 1,000‑fold increase in storage density.
