Quantum physics

Science reporter Jennifer Sills asked scientists to answer the question: “Imagine that you meet all of your research goals. Describe the impact of your research from the perspective of a person, animal, plant, place, object, or entity that has benefited from your success.” Xiangkun (Elvis) Cao, a Schmidt Science Fellow in the MIT Department of Chemical Engineering, shares his response from a photon’s perspective. “I am a photon,” writes Cao. “I started my journey entangled with my significant other at the beginning of the Universe. In the past, humans couldn’t understand me, but then physicists created a quantum computer. At last, I have been reunited with my life partner!”

Writing for Scientific American, Prof. Carlo Ratti explores the “transformative” potential of quantum sensors. Ratti writes that quantum sensors could enable autonomous vehicles to “‘see’ around corners, underwater navigation systems, early-warning systems for volcanic activity and earthquakes, and portable scanners that monitor a person's brain activity during daily life.”

Prof. Alan Guth speaks with Christina Couch of Science Friday about his career and the cosmos. Of what inspired him to pursue a career in science, Guth recalls conducting experiments with a friend and being “very excited about the idea that we can really calculate things, and they actually do reflect the way the real world works.”

Dan Vergano of National Geographic profiles Professor Alan Guth’s career in physics. "What always fascinated me about science was the desire to understand what underlies it all, and I think physics is basically the study of that," Guth explains.
