In the odd world of quantum physics, which even the top experts admit they struggle to understand, this meant anyone watching the reverse of electrons essentially watched time go backwards.
Lead researcher Dr Gordey Lesovik, who heads the Laboratory of the Physics of Quantum Information at the Moscow Institute of Physics Technology (MIPT), said: “We have artificially created a state that evolves in a direction opposite to that of the thermodynamic arrow of time.”
The so-called “time machine” is made up of electron qubits.
Qubits are units of information which are described by a “one”, a “zero”, or a mixed “superposition” of both states.
