A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

In the late 1970s, legendary physicist John Wheeler proposed a radical question: Exactly when does the universe notice that we're paying attention to a quantum experiment? And does it really matter?

MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings demonstrate, with atomic-level precision, the dual yet evasive nature of ...

Researchers demonstrate that some forms of quantum behavior can only occur via pairwise interactions, a finding that limits the number of ways in which we can reconcile quantum mechanics with ...

The concept of light has fascinated scientists for centuries. A recent MIT experiment has reignited the debate about its dual nature. The MIT team revisited a classic experiment with unprecedented ...

Schematic of the MIT experiment: Two single atoms floating in a vacuum chamber are illuminated by a laser beam and act as the two slits. The interference of the scattered light is recorded with a ...
