Researchers Find Way to Transmit Information Using Quantum Trits, or Qutrits

By IQT News posted 06 Sep 2019

(TechnologyReview) Physicists at the University of Science and Technology of China and the University of Vienna in Austria have found a way to transmit even more data than previous efforts by using quantum trits, or qutrits.
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.
The researchers, who include Jian-Wei Pan, a Chinese pioneer of quantum communication, say they have cracked the problem by tweaking the first part of the quantum teleportation process so that senders have more measurement information to pass on to receivers.
