Lead researcher Dr Gordey Lesovik said by putting scattered electrons back into their original shape they had effectively created a state which went against the ‘direction of time’

The “balls” scattered and, according to the laws of physics, should have appeared to split in a haphazard way.

But researchers managed to make them reform in their original order — looking as if they were turning back time.

Lead researcher Dr Gordey Lesovik, of Moscow’s Laboratory of the Physics of Quantum Information, said: “We have artificially created a state that evolves in a direction opposite to that of the thermodynamic arrow of time.”

His team used a rudimentary quantum computer, which carries information on subatomic particles. He hopes their findings, in journal Scientific Reports, will help improve processing power.

Scientists were able to program a quantum computer to “reverse” through time – like balls returning to their starting position in a game of pool

Not quite Dr Who, but even Time Lords had to start somewhere . . .

So how does it work? Well the “time machine” is actually a rudimentary quantum computer made up of electron qubits.

A qubit is a the basic unit of quantum information – a unit that represents one, zero, and both one and zero at the same time.

Researchers ran an “evolution program”, which caused the qubits to enter a complicated changing pattern of ones and zeroes.

And during this process, the order was lost – like hitting balls at the start of a game of pool.

A separeate program then modified the state of this quantum computer so that it evolved backwards, returning from chaos to order.

This allowed the qubits to return to their original starting point.

Scientists were able to perform this so-called “time reversal” successfully 85% of the time with two qubits, and had a 50% success rate with three qubits.
