Research by Physics PhD candidate Sergio Cantu has led to the discovery of a new form of light, which happens when photos stick together, as opposed to passing through one another. “’We send the light into the medium, it gets effectively dressed up as if it were atoms, and then when it turns back into photons they remember interactions that happened in the medium,” Cantu explains to Leah Crane at New Scientist.
MIT physicists have created a new form of light that allows up to three photons to bind together, writes Daniel Oberhaus for Motherboard. While the research is experimental, Oberhaus writes that the trio of photons “are much more strongly bound together and are, as a result, better carriers of information” than other photonic qubits.
Frederick Daso of Forbes highlights MIT alumnus Ryan Robinson, whose startup aims to share unused computational capacity with others who need to perform intensive calculations. This technology will one day “help companies afford cheap, distributed computational power via quantum computing, and allow individuals to make money by loaning out their spare processing power and mining for cryptocurrency,” writes Daso.
Newsweek reporter Katherine Hignett writes that MIT and Harvard researchers have successfully manipulated individual atoms using lasers in one of the largest quantum computer simulations. Hignett writes that, “their technology could help make superfast quantum computers a working reality.”
Boston Globe reporter Alyssa Meyers writes that researchers from MIT and Harvard have demonstrated one of the largest quantum simulators that can trap individual atoms in laser beams. Prof. Vladan Vuletić explains that it is, “a major advance is to be able to align and arrange individual atoms so we can hold on to them and track them.”
Prof. Scott Aaronson speaks with New Scientist reporter Jacob Aron about Google’s D-Wave quantum computer. “This is certainly the most impressive demonstration so far of the D-Wave machine’s capabilities,” says Aaronson. “And yet, it remains totally unclear whether you can get to what I’d consider ‘true quantum speedup’ using D-Wave’s architecture.”
Professor Vladan Vuletić and his colleagues have successfully developed a new technique for simulating friction between two surfaces at the nanoscale, reports Davide Castelvecchi for Nature. The research “could bring enormous savings by reducing friction between the moving parts of machines,” writes Castelvecchi.
Robert Ferris writes for CNBC that MIT researchers have developed a new technique for creating surfaces that can slide past each other without friction. The researchers hope to use the technique to “build devices that can preserve themselves by being nearly immune to friction.”
New Scientist reporter Jacob Aron writes about MIT graduate student Theodore Yoder’s work upgrading a quantum search algorithm to make it more effective. The new algorithm lets users “hone in on specific answers without knowing in advance how many there are,” Aron explains.
