According to Bitzenbauer, this approach opens the door to modern quantum technologies, be it quantum cryptography or quantum computing.

One of the aims of quantum cryptography is to make communication secure against eavesdropping.

This provides a new tool for quantum communication and information processing in which entangled photon pairs can serve as distributed keys in quantum cryptography or store information in a quantum memory device.

If so, such nonlocality would equal or rival Bell nonlocality, an understanding of which has paved the way for quantum communications and quantum cryptography.

This year’s Nobel Prize in Physics goes to scientists from France, the United States, and Austria whose work laid the foundation for quantum cryptography and quantum computing.
