For decades, physicists believed that even the strangest quantum objects had a hard limit on how strongly their behaviour could be linked across time.
No matter how quantum a system was, there was thought to be a ceiling to how much its present could be correlated with its past and future.
However, now, a team of researchers from India and Poland has shown that this limit can be dramatically broken using a qubit, one of the most basic building blocks of quantum technology.
By letting a qubit evolve under a superposition (the property that enables a quantum object to exist in multiple states at the same time) of different time evolutions, they have pushed quantum correlations (the link between quantum objects or systems) beyond what was long considered an unbreakable bound.
