“Much the way the individual components in mobile phones will eventually fail, so too do quantum systems,” said lead researcher Michael J. Biercuk from the University of Sydney.
“But in quantum technology the lifetime is generally measured in fractions of a second, rather than years.”
“But what if the rules changed randomly while the ball was on its way to you? In that case it’s next to impossible to predict the future behaviour of that ball,” Biercuk adds.
“And yet this situation is exactly what we had to deal with because the disintegration of quantum systems is random. Moreover, in the quantum realm, observation erases quantumness, so our team needed to be able to guess how and when the system would randomly break.”
“We know that building real quantum technologies will require major advances in our ability to control and stabilise qubits – to make them useful in applications,” says Biercuk.
