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 ...

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 ...

A thought experiment that was at the heart of an argument between famed physicists Albert Einstein and Niels Bohr in 1927 has finally been made real. Its findings elucidate one of the core mysteries ...

A near-100-year-old debate between the theoretical physicists Albert Einstein and Niels Bohr has finally been settled—and not in the former’s favor. A team of physicists in China have realized a ...
