“Qutrit” Experiments Are a First in Quantum Teleportation
So, I guess this means that &quot;qutrit&quot; computing is kind of like ternary (or &quot;trinary&quot;) computing [1] with 3 well defined states.  I got interested in trinary when I read somewhere that Russian scientists had at one point built a trinary computer (can&#x27;t remember where I saw that) and I sat down and did the trinary math because it was interesting - and it worked.<p>Perhaps in qubit computing (speculating as I am not an expert), it is harder to detect the difference between the states which are somewhere in between 1 and 0, leading to the needs for error correction, but I also thought that, that particular property of qubit computing was interesting for its unpredictability, if it could be harnessed.  Since a lot of machine learning models (example, Monte Carlo) use randomness, I always wondered how lack of precision might be an advantage.  Out of my level of knowledge here a bit if anyone has any thoughts.<p>I had to look it up and, I&#x27;m not a quantum expert, but it seems my gut feeling was basically right:
&quot;Similar to the qubit, the qutrit is the unit of quantum information that can be realized in suitable 3-level quantum systems. This is analogous to the unit of classical information trit of ternary computers. Note, however, that not all 3-level quantum systems are qutrits. The term &quot;qu-d-it&quot; (quantum d-git) denotes the unit of quantum information that can be realized in suitable d-level quantum systems.&quot; [2]<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Ternary_computer" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Ternary_computer</a><p>[2] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Qubit" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Qubit</a>
