Quantum Internet: First Teleportation To A Solid-State Quantum Memory

Quantum Teleportation
A European team of physicists has demonstrated a device that can teleport quantum information to a solid-state quantum memory over telecom fibre, a crucial capability for any future quantum internet.

Quantum teleportation is the ability to transmit from one location to another without travelling through the space in between. Matter itself doesn’t make this journey, only the information that describes it. This is transmitted to a new body that takes on the identity of the original.

But while science fiction fans have focused on body involved, quantum physicists are more interested in the information. For them, teleportation is the enabling technology behind a new generation of information processing technologies including a quantum internet that allows information to be transmitted with perfect security.
