New, highly sensitive experiments required to find potential violations.

The physical conditions that support a geometric interpretation of spacetime, such as the equivalence between rest and inertial mass, are shown not to be necessarily valid in the quantum regime, and a quantum formulation is provided.

By combining quantum mechanical quirks of light with a technique called photonic force microscopy, scientists can now probe detailed structures inside living cells like never before. This ability could bring into focus previously invisible processes and help biologists better understand how cells work.

Photonic force microscopy is similar to atomic force microscopy, where a fine-tipped needle is used to scan the surface of something extremely small such as DNA. Rather than a needle, researchers used extremely tiny fat granules about 300 nanometers in diameter to map out the flow of cytoplasm inside yeast cells with high precision.

To see where these miniscule fat particles were, they shined a laser on them. Here, the researchers had to rely on what’s known as squeezed light. Photons of light are inherently noisy and because of this, a laser beam’s light particles won’t all hit a detector at the same time. There is a slight randomness to their arrival that makes for a fuzzy picture. But squeezed light uses quantum mechanical tricks to reduce this noise and clear up the fuzziness.

A controversial new paper argues that universes with dark energy profiles like ours do not exist in the “landscape” of universes allowed by string theory.

WASHINGTON – U.S. Reps. Lamar Smith (R-Texas) and Eddie Bernice Johnson (D-Texas), who serve as the chairman and ranking member of the House Committee on Science, Space, and Technology, and U.Sens. John Thune (R-S.D.) and Bill Nelson (D-Fla.), who serve as the chairman and ranking member of the Senate Committee on Commerce, Science, and Transportation, today announced the introduction of House and Senate companions of the National Quantum Initiative Act. The legislation would accelerate and coordinate public and private quantum science research, standards, and workforce development to give the United States a competitive advantage as China and Europe vie to achieve technological breakthroughs in this field.

Chairman Smith: “The National Quantum Initiative Act will accelerate the development of quantum information science in the United States and secure our leadership in the quantum sector. As other nations are rapidly developing their own quantum programs, the U.S. faces the risk of falling behind. This legislation provides a path forward to ensure that the U.S. secures its influence in the next generation of science and technology. I am glad that Senator John Thune has joined me in introducing this legislation, along with our respective Ranking Democrat Committee Members Rep. Eddie Bernice Johnson and Senator Bill Nelson.

”The bill creates a 10-year federal program that will significantly develop our quantum knowledge. It will bring a whole of government approach to advance QIS to the next level of research and development, while also creating public-private partnerships, leveraging the resources and expertise of government, industry and academia. Through new research facilities and a strong workforce pipeline, students and researchers will have greater resources and opportunities to develop their quantum skills and create the next great computing innovation. There is no doubt quantum technology will revolutionize our world to come. This bill secures American leadership in quantum science and guarantees a first place finish in the great quantum race.”

Philip Ball lauds a study of a famous experiment and the insights it offers into a thoroughly maddening theory.

The rotor—which is actually a tiny spinning dumbbell that a laser levitates—spins at more than 60 billion rotations per minute.

A new bill aims to support a growing quantum industry by training a new cross-disciplinary workforce.
