Reversal of Time Through The Use Of Quantum Computer

Researchers from the Moscow Institute of Physics and Technology collaborated with their colleagues from the United States and Switzerland. They managed to return the condition of a quantum computer, just a fraction of a second into the past. Lead author of the study, who is also the head of the Laboratory of the Physics of Quantum Information Technology at MIPT, Gordey Lesovik said that this is the first time when researchers have looked into the possibility of violating the second law of thermodynamics. This particular law is quite closely associated with the idea of the arrow of time, which positions time in a one-way direction from the past and on to the future.

Gordey Lesovik said that they had started off by giving a description of some sort of a local perpetual motion machine of the second type. In the month of December, they had published a paper, which discussed the violation of the second law through a device known as Maxwell’s demon. The latest paper looks into the same problem from the third point of view. The researchers have artificially created a state, which tends to evolve in the opposite direction to that of the thermodynamic arrow of time. Majority of the laws in Physics fail to differentiate between the past and the future.

The researchers then carried out an experiment of four stages, in their attempt to reverse time. They found out that in almost 85 percent of the instances, the two-qubit quantum computer made its way back to the initial state. Whenever three qubits were involved, a number of errors occurred, which ultimately resulted in a success rate of 50 percent. Now, with the design of more sophisticated devices, it is expected that the error rate would fall.
