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 ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to Albert Einstein’s instincts about reality. By stripping classic thought ...

A groundbreaking experiment demonstrates yet again that light exists both as a wave and a particle in the quantum world—but we can’t see both at the same time. Reading time 3 minutes Albert Einstein ...

The nature of quantum entanglement remains an outstanding problem in physics. But Albert Einstein's theories, along with insights from quantum computing, could finally put the mystery to rest. When ...

Einstein called it “spooky action at a distance,” but today quantum entanglement is poised to revolutionize technology from computers to cryptography. Physicists have gradually become convinced that ...
