Physicists from the Chinese University of Science and Technology and the University of Vienna were able to transmit a record amount of data in quantum form. Previously, scientists have been able to send both on earth and via satellites information in quantum qubits. Now the researchers have mastered a new unit of storage of quantum information.
Scientists have managed to convey information in a quantum way larger than ever before. For this purpose, they used the so-called quantum qutrits. Normal bits can only represent a value of "1" or "0". Qubits can simultaneously represent both "1" and "0", so they are able to accommodate more information. Kutrite can have three different states: "0", "1" and "2". Theoretically, they can be transmitted using quantum teleportation.
The transmission of information using qubits rather complicated process and qutrits is still more complicated due to the presence of extra dimensions. However, Jian Wei Pan of the Chinese University of science and technology says that they managed to solve the problem. They managed to set up the first part of the teleportation process so that the senders had more information about the transmitted data. This will help recipients determine which data was sent to them.
A peculiarity of quantum communication is the fact that when interfering with the connection of unauthorized persons, quantum units of information change their state, notifying channel owners about a hack. The use of qutrits can become the basis for the creation of an ultra-secure quantum Internet, with the help of which important data can be transmitted.
