Scientists Say They Can Reverse Time in a Quantum System

Posted by in categories: particle physics, quantum physics

An international team of scientists claim to have found a way to speed up, slow down, and even reverse the clock of a given system by taking advantage of the unusual properties of the quantum world, Spanish newspaper El País reports.

In a series of six papers, the team from the Austrian Academy of Sciences and the University of Vienna detailed their findings. The familiar laws of physics don’t map intuitively onto the subatomic world, which is made up of quantum particles called qubits that can technically exist in more than one state simultaneously, a phenomenon known as quantum entanglement.

Now, the researchers say they’ve figured out how to turn these quantum particles’ clocks forward and backward.
