Using Google's 70-qubit quantum computer, University of Texas at Austin (UT Austin) researchers showed how taking certain measurements on a quantum computer results in different phases of quantum information.
The researchers observed quantum teleportation, in which quantum states instantaneously are sent from one point in space to another, but found information sent in this manner appears purely random on the receiving end and cannot be controlled.
Nevertheless, they said, the findings potentially could be used to manage noise in more powerful quantum computers.
UT Austin's Matteo Ippoliti said, "From the signal we measured, we can learn about noise in the system, that is to say, imperfections in the quantum computation that cause it to lose accuracy over time. This is very important for near-term quantum computers, where we don't yet have the ability to correct errors."
