Quantum Teleportation

Abstract

Quantum teleportation is a technique for transferring quantum information from a sender at one location to a receiver some distance away. While teleportation is commonly portrayed in science fiction as a means to transfer physical objects from one location to the next, quantum teleportation only transfers quantum information. In July, the US Department of Energy unveiled a blueprint for the first quantum internet, connecting several of its National Laboratories across the country. A quantum internet would be able to transmit large volumes of data across immense distances at a rate that exceeds the speed of light. Traditional computer data is coded in either zeros or ones. Quantum information is superimposed in both zeros and ones simultaneously. Academics, researchers and IT professionals will need to create devices for the infrastructure of quantum internet including: quantum routers, repeaters, gateways, hubs, and other quantum tools.

The “traditional internet,” as the regular internet is sometimes called, will still exist. It is expected that large organizations will rely on the quantum internet to safeguard data, but those individual consumers will continue to use the classical internet.

Quantum Teleportation toward the Quantum Internet: A Concise Review

Yang-Bin Ma, Yun-Ru Fan, Ri-Yao Song +8 more

Quantum networks play a pivotal role in quantum information science, which not only provide a secure communication platform for remote access to quantum computers but also serve as the strategic core for achieving large-scale quantum information processing, forming the foundational infrastructure for the future global-scale quantum internet. Quantum teleportation, which enables the transmission of unknown quantum states over long distances by employing quantum entanglement together with classical communication, is essential for the distribution of quantum resources in the construction of the global-scale quantum internet. To realize a global-scale quantum internet, quantum repeater protocols represent one of the most promising approaches for enabling quantum communication between any nodes. This concise review presents representative experimental demonstrations of quantum teleportation for constructing quantum networks across different physical platforms. Along this trajectory, the review discusses current challenges, open issues, and future perspectives toward scalable and practical quantum internet.

Quantum Internet

Ahmed Banafa

Building a quantum internet is a key ambition for many countries around the world as such a breakthrough will give them competitive advantage in a promising disruptive technology, and opens a new world of innovations and unlimited possibilities. Recently the US Department of Energy published the first blueprint of its kind, laying out a step-by-step strategy to make the quantum internet dream come true. A quantum internet would be able to transmit large volumes of data across immense distances at a rate that exceeds the speed of light. Academics, researchers, and IT professionals will need to create devices for the infrastructure of quantum internet including: quantum routers, repeaters, gateways, hubs, and other quantum tools. A whole new industry will be born based on the idea of a quantum internet existing in parallel with the current ecosystem of companies the authors have in a regular internet.

Building a quantum internet is a key ambition for many countries around the world; such a breakthrough will give them competitive advantage in a promising disruptive technology and opens a new world of innovations and unlimited possibilities. Quantum security leads us to the concept of quantum cryptography which uses physics to develop a cryptosystem completely secure against being compromised without the knowledge of the sender or the receiver of the messages. A quantum internet would be able to transmit large volumes of data across immense distances at a rate that exceeds the speed of light . Quantum cryptography uses photons to transmit a key. Once the key is transmitted, coding and encoding using the normal secret-key method can take place.
