Researchers create quantum calculator
Researchers have developed a special type of quantum computer, known as a quantum simulator, that is programmed by capturing super-cooled rubidium atoms with lasers and arranging them in a specific order, then allowing quantum mechanics to do the necessary calculations.

Flipping the switch
Harvard researchers have succeeded in creating quantum switches that can be turned on and off using a single photon, an achievement that could pave the way for the creation of highly secure quantum networks.

Stars in the making
A paper authored by Harvard’s Eli Visbal with colleagues from the California Institute of Technology and Tel Aviv University suggests that it may be far easier than commonly thought to peer deep into the universe’s history and observe the telltale signs of the formation of the first stars and galaxies.

Quantum computing, no cooling required
Using a pair of impurities in ultra-pure, laboratory-grown diamonds, researchers have created room-temperature quantum bits and have stored information in them for nearly two seconds — an increase of nearly six orders of magnitude over the life span of earlier systems. The work, described in the June 8 issue of Science, is a critical first…

Elegant entanglement
Harvard scientists have taken a critical step toward building a quantum computer — a device that could someday harness subatomic particles such as electrons to perform calculations far faster than the most powerful supercomputers.

A vision of computing’s future
In 1978, while a student at Harvard Business School, Dan Bricklin conceived of VisiCalc, the first electronic spreadsheet program for personal computers. The result helped to spark a digital revolution in business and made desktop computers a must-have item in many offices.

With a little help from his PC
With “The Ringo Starr Fine Art Show” paying a visit to 60 Church St. in Harvard Square for a three-day stint starting today (June 7), some might assume that the man who rocked the kit for the most influential band in the history of rock ’n’ roll has traded in his sticks for paint and…
