Riken’s Quantum Leap: Exploring Ultrafast World with Attosecond Laser Pulses.

Quantum Leap: Frequency-Domain Entanglement In a groundbreaking development, physicists have unveiled a novel type of quantum entanglement, termed as frequency-domain photon number-path entanglement. This pioneering discovery revolves around a cutting-edge device known as a frequency beamĀ splitter. Remarkably, this device can modify the frequency of photons, achieving a remarkable 50% rate of success. Historically, the focus […]
