Scientists are one step closer to creating a super-secure quantum Internet

Scientists from the Chinese University of Science and Technology and the University of Vienna in Austria have proven the possibility of transmitting information both overland and via satellites using quantum bits - qubits. Now they have found a way to send even more data using the so-called quantum tritas - kutritas.

Quantum technology promises to securely send data over long distances. The common bits used to encode everything from financial records to YouTube videos are streams of electrical or photonic impulses that can represent 1 or 0.Qubits, which are usually electrons or photons, can carry more information as they can be polarized. in two directions at once, so they can represent both 1 and 0 at the same time. Qutrits, which can be polarized in three different dimensions at the same time, can carry even more information. In theory, this could be transmitted using quantum teleportation.

Quantum sending of data is based on entanglement. Entangled quantum particles can influence each other's state, even if they are on different continents. At the time of sending, both sides of the communication receive one pair of entangled qubits. The sender measures the interaction of his qubit with another containing the data he wants to send.

At the same time, interference with quantum information units leads to the loss of their quantum state, leaving a clear sign of hacking. If used on a large scale, qutrits could become the backbone of the ultra-secure quantum internet that can be used to send sensitive government and commercial data.
