An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the quantum debate.

Researchers have discovered new ways to shape quantum light, creating high-dimensional states that can carry much more ...

“Einstein and Bohr would have never thought that this is possible, to perform such an experiment with single atoms and single photons,” said Wolfgang Ketterle, head of the MIT group whose new ...

Scientists have introduced a groundbreaking form of quantum entanglement known as frequency-domain photon number-path entanglement. This leap in quantum physics involves an innovative tool called a ...

Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether Albert Einstein or Niels Bohr had the better grasp of the quantum world. Now a ...
