Superconductors are among the most puzzling materials in physics. They conduct electricity with zero resistance, but only under specific conditions that researchers have struggled for decades to fully ...

A message from the future sounds like science fiction, until someone starts asking how many bits it could actually carry.

One of the film’s most memorable scenes shows Cooper sending messages to his daughter from inside a black hole. While the sequence was designed as science fiction, new research suggests the underlying ...

What does the passage of time look like for a truly quantum object? The world’s best clocks may soon be able to answer this question, testing how time can stretch and shift in the quantum realm and ...

The gauge bosons of the standard model of particle physics are responsible for three of the four known forces in the universe ...

In new research published in Physical Review X, scientists have designed quantum control protocols that generate processes more consistent with time flowing backward than forward. The ...

Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: its passage depends on motion and gravity. But when combined with quantum ...

Scientists have, for the first time, experimentally proven that angular momentum is conserved even when a single photon splits into two, pushing quantum physics to its most fundamental limits. Using ...

Quantum systems can secretly “remember” their past—even when they appear not to. Scientists found that whether a system shows memory depends on how you look at it: through its evolving state or its ...

Well, around a similar time, the American Physical Society (APS) invited researchers and science enthusiasts to chime in on 10 broad questions on major concepts—of arguable contention—in physics as a ...
