"The “time machine” described in the journal Scientific Reports consists of a rudimentary quantum computer made up of electron “qubits”. A qubit is a unit of information described by a “one”, a “zero”, or a mixed “superposition” of both states."

"In the experiment, an “evolution program” was launched which caused the qubits to become an increasingly complex changing pattern of zeros and ones."

"But then another program modified the state of the quantum computer in such a way that it evolved “backwards”, from chaos to order.

It meant the state of the qubits was rewound back to its original starting point."
