For the first time, a team of Princeton physicists have been able to link together individual molecules into special states that are quantum mechanically “entangled.” In these bizarre states, the molecules remain correlated with each other—and can interact simultaneously—even if they are miles apart, or indeed, even if they occupy opposite ends of the universe. This research was recently published in the journal Science.

“This is a breakthrough in the world of molecules because of the fundamental importance of quantum entanglement,” said Lawrence Cheuk, assistant professor of physics at Princeton University and the senior author of the paper. “But it is also a breakthrough for practical applications because entangled molecules can be the building blocks for many future applications.”

These include, for example, quantum computers that can solve certain problems much faster than conventional computers, quantum simulators that can model complex materials whose behaviors are difficult to model, and quantum sensors that can measure faster than their traditional counterparts.

Liftoff occurred at 12:07 a.m. ET on Thursday (Dec. 7).

Quantum bits are potentially powerful but notoriously error-prone. Now a Harvard team says it has found a way to prevent mistakes — by manipulating individual atoms with laser beams — making quantum processing much more efficient.

The idea that sprinkling rock dust on farmland can soak up atmospheric carbon will be tested at large scale thanks to a $57 million purchase from corporations including Stripe and Alphabet.

Researchers at universities in New York and Ningbo, China, say they have created tiny robots built from DNA that can reproduce themselves.

Such nanorobots could one day launch search-and-destroy missions against cancer cells within a human’s bloodstream without the need for surgery or collect toxic waste from the ocean.

The tiny mechanism is so small that 1,000 of them could fit into the width of a sheet of paper.

A proposed model unites quantum theory with classical gravity by assuming that states evolve in a probabilistic way, like a game of chance.

Physicists’ best theory of matter is quantum mechanics, which describes the discrete (quantized) behavior of microscopic particles via wave equations. Their best theory of gravity is general relativity, which describes the continuous (classical) motion of massive bodies via space-time curvature. These two highly successful theories appear fundamentally at odds over the nature of space-time: quantum wave equations are defined on a fixed space-time, but general relativity says that space-time is dynamic—curving in response to the distribution of matter. Most attempts to solve this tension have focused on quantizing gravity, with the two leading proposals being string theory and loop quantum gravity. But new theoretical work by Jonathan Oppenheim at University College London proposes an alternative: leave gravity as a classical theory and couple it to quantum theory through a probabilistic mechanism [1].

As demand for electric vehicles soars, scientists are searching for materials to make sustainable batteries. Lignin, from waste paper pulp, is shaping up to be a strong contender.

The mainstay material of electronics is now yielding better energy storage.
