Quantum data transfer technology: what does that even mean? Well, according to physicists at the University of Science and Technology of China and the University of Vienna in Austria, it means sending record-shattering amounts of data using a unit of quantum information called “qutrit”‘s.
An MIT Technology Review report says quantum data transfer has seen its share of promising study already, with one instance where scientists transmitted data both on land and via satellites using quibits.
But now, quantum trits, or qutrits, can ship even more data. The report explains:
Conventional bits used to encode everything from financial records to YouTube videos are streams of electrical or photonic pulses than can represent either a 1 or a 0. Qubits, which are typically electrons or photons, can carry more information because they can be polarized in two directions at once, so they can represent both a 1 and a 0 at the same time. Qutrits, which can be polarized in three different dimensions simultaneously, can carry even more information. In theory, this can then be transmitted using quantum teleportation. — MIT Technology Review report.
Though working with qubits is far from easy, the researchers say that can tweak the data teleportation process so the sender has more decoding info to pass to the receivers.
Hacker Deterrence: another benefit of quantum data transfer
Cybersecurity could greatly benefit from using qutrits for quantum information transfer. While hackers can access conventional data on the internet without necessarily betraying that they’ve accessed it, they could not do so with quantum units of info, since they’re already in such a delicate state.
Qutrits — if harnessed on any real scale — could be used to form an ultra-secure network that has a built-in intruder alert.
