Quantum Internet Getting Closer

 Advances in Data Teleportation indicated.

'Quantum Internet' Inches Closer With Advance in Data Teleportation  By The New York Times, May 26, 2022

From Santa Barbara, CA, to Hefei, China, scientists are developing a new kind of computer that will make today's machines look like toys.

Harnessing the mysterious powers of quantum mechanics, the technology will perform tasks in minutes that even supercomputers could not complete in thousands of years. In the fall of 2019, Google unveiled an experimental quantum computer showing this was possible. Two years later, a lab in China did much the same.

But quantum computing will not reach its potential without help from another technological breakthrough. Call it a "quantum internet" — a computer network that can send quantum information between distant machines.

At the Delft University of Technology in the Netherlands, a team of physicists has taken a significant step toward this computer network of the future, using a technique called quantum teleportation to send data across three physical locations. Previously, this was possible with only two.

First Multi-Node Quantum Network Paves the Way for the Quantum Internet

 Though still a small number of qubits,  but the connectivity into a 'quantum internet' appears to be a big step forward.

 First Multi-Node Quantum Network Paves the Way for the Quantum Internet By ZDNet  April 16, 2021

Researchers in the Netherlands have successfully connected three separate quantum processors in what is effectively the world's first multi-node quantum network. This paves the way for a large-scale quantum internet that governments and scientists have been dreaming up for decades.

QuTech, a quantum research institute based in Delft, has published new work in which three nodes that can store and process quantum bits (also called qubits) were linked. This, according to the QuTech researchers, is the world's first rudimentary quantum network.

It would be the harbinger of an entirely new medium of calculation, harnessing the powers of subatomic particles to obliterate the barriers of time in solving incalculable problems.

Connecting quantum devices is by no means a novelty: many researchers around the world are currently working on similar networks, but so far have only succeeded in linking two quantum processors. Establishing a multi-node connection, therefore, is a key step towards significantly expanding the size of the network.

Quantum Wavelength Switch

Interesting direction outlines.   Note the number of users in the quantum network being key.

Quantum Internet Closer to Reality, Thanks to This Switch

By Purdue University News,  March 3, 2021

A new study has found that using a programmable wavelength-selective switch can help increase the number of users in a quantum network without increasing photon loss from the switching device.

Engineers at Purdue University and the U.S. Department of Energy's Oak Ridge National Laboratory have overcome an obstacle in the development of a quantum Internet via a programmable switch that adjusts the amount of data sent to each user by selecting and rerouting wavelengths of light carrying data channels.

This could increase user numbers without incurring greater photon and data loss as the network expands. The approach removes the need to physically interchange many fixed optical filters tuned to individual wavelengths, by simply programming the switch to route data-carrying wavelengths to each new user.

The switch also can be programmed to modify bandwidth based on user needs.  ... " 

Sustained, High-Fidelity Quantum Teleportation

Quantum Internet is quickly approaching.   Implications?

Fermilab and Partners Achieve Sustained, High-Fidelity Quantum Teleportation  University of Chicago News,  December 28, 2020

Researchers at Fermi National Accelerator Laboratory (Fermilab), AT&T, the California Institute of Technology (Caltech), Harvard University, the NASA Jet Propulsion Laboratory, and the University of Calgary in Canada have demonstrated for the first time a sustained, long-distance teleportation of qubits made of photons with fidelity greater than 90%, paving the way for a quantum Internet. The qubits were teleported over a 27-mile-long fiber-optic network using state-of-the art single-photon detectors and off-the-shelf equipment. Fermilab's Panagiotis Spentzouris said the demonstration was a “key achievement on the way to building a technology that will redefine how we conduct global communication.”

Title: Quantum Networks: From a Physics Experiment to a Quantum Network System

Date: Tuesday, September 01, 2020    Duration: 1 hour 
Time: 11:00 AM Eastern Daylight Time

Summary
The internet has had a revolutionary impact on our world. The vision of a quantum internet is to provide fundamentally new internet technology by enabling quantum communication between any two points on Earth. Such a quantum internet can —in synergy with the “classical” internet that we have today—connect quantum information processors in order to achieve unparalleled capabilities that are provably impossible by using only classical information.

At present, such technology is under development in physics labs around the globe, but no large-scale quantum network systems exist. In this talk, we will discuss some of the efforts to move from an ad-hoc physics experiment to a scalable quantum network system. We start by providing a gentle introduction to quantum networks for computer scientists, and briefly review the state of the art. We continue to present a network stack for quantum networks, and a give an overview of a link layer protocol for producing quantum entanglement as an example.

We close by providing a series of pointers to learn more, as well as tools to download that allow play with simulated quantum networks without leaving your home.

US Wants to Build an Unhackable Quantum Internet

What does unhackable mean here?   

U.S. Hatches Plan to Build Quantum Internet That Might Be Unhackable
The Washington Post
Jeanne Whalen
July 23, 2020

U.S. officials and scientists yesterday unveiled a plan to construct a potentially hackproof quantum Internet to operate parallel to the world's existing networks. The Department of Energy (DoE) and its national laboratories will form the project's main support pillar, and DoE official Paul Dabbar suggested it could be funded using some of the $500 million to $700 million in annual federal quantum information technology investments. A quantum Internet relies on entangled photons to share information over long distances without physical links; the race to create one is a global competition. Researchers said attempts to observe or disrupt photons or quantum bits in a quantum Internet would automatically change their state and destroy the transmitted information. A quantum Internet also could interconnect various quantum systems and boost their computing power.  ... '

Quantum Data Classification

The Quantum internet is an interesting concept, can this mean understanding how information has been derived, and thus its identity and ownership?

Quantum Data Classification Protocol Brings Us Nearer to Future 'Quantum Internet'
Universitat Autonoma de Barcelona (Spain)
November 8, 2019

Researchers at Spain’s Universitat Autonoma de Barcelona have developed a protocol that sorts and classifies quantum data by the state in which it was prepared, more efficiently than the comparable classical algorithm. The process identifies clusters of identically prepared quantum systems via a natural link to an archetypal form of classical machine learning: clustering data samples based on a common underlying probability distribution. The researchers also compared the performances of classical and quantum protocols, observing the new protocol significantly overtakes classical approaches, especially for large dimensional data. The protocol is envisioned as a step closer to realizing a quantum Internet, as it establishes a concrete theoretical framework on what is physically possible in the automated classification and distribution of quantum data.  ....
