Back to the future: Chinese team’s record transmission lays ground for quantum internet https://www.byteseu.com/776399/ #BeijingAcademyOfQuantumInformationSciences #LongGuilu #NorthChinaUniversityOfTechnology #QSDC #QuantumCommunication #QuantumInternet #QuantumKeyDistribution #QuantumPhysics #Science #ScienceAdvances #SensitiveInformation #TelecommunicationsOpticalFibre #TransmissionRecord #UltraSecureConnection #voice #WebSecurity
The future of quantum optics and photonics promises the potential of a secure quantum internet that could revolutionize data protection. Achieving this requires controlling photons over vast distances, a field that saw a breakthrough when a Chinese satellite set a record for transmitting entangled photons. What’s next? Innovations could include longer-distance photon entanglement, improved quantum repeaters, and advances in quantum communication protocols.#QuantumInternet #Photonics #FutureTech
Now at the Workshop for #Quantum Repeaters and Networks in Montreux. Life is rough! (Photos coming, too.)

Scientists have created an "exceptionally bright" light source that can generate quantum-entangled photons (particles of light) which could be used to securely transmit data in a future high-speed quantum communications network. Live Science reports:

By now, hopefully you can see that there is an ABSOLUTELY CRITICAL NEED for data center-scale #QuantumNetworks. There are also Big Science things you can do with a wide-area #QuantumInternet or with related technology such as LIGO's squeezing.

This #QuantumInternet #QuantumEntanglement thread is more than long enough. Let's finish up.

While it's not the same thing as the entangled #QuantumInternet, one use of related technology is in production in LIGO, the gravitational wave observatory, which uses squeezed light:

For one summary of these three categories aimed at advancing work on #QuantumInternet within the Internet engineering community (#IETF and #IRTF), see
https://datatracker.ietf.org/doc/draft-irtf-qirg-quantum-internet-use-cases/
IETF DatatrackerApplication Scenarios for the Quantum InternetThe Quantum Internet has the potential to improve application functionality by incorporating quantum information technology into the infrastructure of the overall Internet. This document provides an overview of some applications expected to be used on the Quantum Internet and categorizes them. Some general requirements for the Quantum Internet are also discussed. The intent of this document is to describe a framework for applications, and describe a few selected application scenarios for the Quantum Internet.This document is a product of the Quantum Internet Research Group (QIRG).

You described the #QuantumInternet as "a solution in search of a problem", and while that's rather glib, it's not completely unjustified. The shift analog-->digital-->quantum information is so deep and profound, we will be exploring it for decades.

Your video on #QuantumInternet brings up some interesting points, which I want to explore in a little more depth than you went into.

Hi Sabine, let's talk #QuantumInternet. We did this a few years ago, when I generated a tweetstorm about #QuantumComputerArchitecture, and I had been thinking it was about time to do something similar for quantum communications and Quantum Internet.

#QuantumInternet thread coming up. This was posted first on the bird site to contact the creator of the video that prompted it, so some of it is written second person to her.
Okay, folks, I'm gonna have to do a long thread on #QuantumInternet. Keep your eyes peeled...
I will be in Brisbane for #IETF119 #IETFDownUnder starting on Sunday. See you there!
And #QuantumInternet Research Group meeting on Wednesday. Be there -- we'll have good talks on routing, and on the "timing regimes" for how to decide layering.

arXiv.orgQuantum CommunicationsThe second quantum revolution has been picking up momentum over the last decade. Quantum technologies are starting to attract more attention from governments, private companies, investors, and public. The ability to control individual quantum systems for the purpose of information processing and communication is no longer a theoretical dream, but is steadily becoming routine in laboratories and startups around the world. With this comes the need to educate the future generation of quantum engineers. This textbook is a companion to our video lectures on Overview of Quantum Communications from the Q-Leap Education project known as Quantum Academy of Science and Technology. It is a gentle introduction to quantum networks, and is suitable for use as a textbook for undergraduate students of diverse background. No prior knowledge of quantum physics or quantum information is assumed. Exercises are included in each chapter.
