Critical Step in Quantum Networking

Researchers have produced, stored, and retrieved quantum information for the first time, a critical step in quantum networking.

The ability to share quantum information is crucial for developing quantum networks for distributed computing and secure communication. Quantum computing will be useful for solving some important types of problems, such as optimizing financial risk, decrypting data, designing molecules, and studying the properties of materials.

“Interfacing two key devices together is a crucial step forward in allowing quantum networking, and we are really excited to be the first team to have been able to demonstrate this.” — Dr. Sarah Thomas

However, this development is being held up because quantum information can be lost when transmitted over long distances. One way to overcome this barrier is to divide the network into smaller segments and link them all up with a shared quantum state.

To do this requires a means to store the quantum information and retrieve it again: that is, a quantum memory device. This must ‘talk’ to another device that allows the creation of quantum information in the first place.

For the first time, researchers have created such a system that interfaces these two key components, and uses regular optical fibres to transmit the quantum data.

There is no commercial value in this or quantum networking. No one is going to use this to optimize financial risk, design molecules, or increase the secutiry of anything.


  1. Here a quantum, there a quantum, everywhere a quantum quantum. Buzz buzz buzz, and more buzz. You might think if you only put the word 'quantum' into a phrase, any phrase, it turned into a great idea worth its weight in gold.

    A buzzword is just dressed up bullshit trying to sound clever and meaningful.
