A team of researchers from NASA, Caltech and Fermilab has published a paper announcing the first long-range Quantum Teleportation technology, laying the groundwork for a quantum network that could one day revolutionize computer computing.
The Daily Mail reports that quantum teleportation uses a phenomenon called quantum entanglement to link two particles together to share information about each other precisely and instantaneously. Even if they are separated by long distances, the quantum state of each particle will still depend on the state of the other particle, and quantum teleportation is the instantaneous transmission of quantum states from one location to another.
The report explains that quantum teleportation is the instantaneous transmission of quantum information units called “quantum bits” (Qubit). The speed of transmission of quantum bits at a distance of about 43.5 km will be faster than the speed of light, and the information in the quantum network is stored in quantum bits and transmitted over long distances or long distances through the phenomenon of quantum entanglement. Because the entire communication system using photons, not using hackers can break the computer code, will be faster and more secure than the general network.
However, quantum teleportation is extremely sensitive to environmental interference, to actually prove the theoretical technology is challenging.
The report said the research team conducted the latest experiments in two laboratories nearly 44 kilometers apart to establish a prototype of the quantum network. The system contains three nodes that interact with each other to trigger quantum bit sequencing, sending signals from one place to another instantly. According to the research team’s paper published in PRX Quantum, teleportation occurs instantly at faster than the speed of light, with a fidelity of more than 90%.
The newspaper pointed out that, compared to the world’s most complex supercomputer, the quantum computer running in the quantum network may be more than about 100 trillion times faster, although the technology is still undergoing complex testing, but policy makers have begun to plan the use of the way, the U.S. Department of Federal Energy hopes to establish a quantum network between laboratories in various states. Caltech professor Maria Spiropulu joked to reporters that netizens have asked through social media whether they should look for quantum network providers to sign up, acknowledging that more research and development is needed.
