Move, Tardis: Scientists just reported that they had managed to return time with a quantum computer.
A team of scientists from the Moscow Physical Technology Institute, USA and Switzerland, published their findings. Scientific reports and said they have turned time with a fraction of a second of IBM's quantum computer . In the report, scientists have also determined "the likelihood that an electron in the empty interstellar space will return to a random principle back in its recent past," Phys.org notes.

According to the report, the origin of the "arrow of time" is still a great scientific challenge. The scientists' experiment disputes the second law of thermodynamics, which dictates the direction of past events to the future, and includes the transition of energy into usable to unusable systems, writes The Daily Mail.
Most physical laws make no difference between the past and the future, but scientists say their experiment, which includes "reversing time", shows that these laws can be broken. For their research, scientists were curious whether individual particles could turn impulsively toward themselves.
In order to put this concept on the test, the scientists formulated two separate hypotheses: The opposite time would require super-systemic manipulation and "in most cases," probably happening in nature. Secondly, if a super system "appears for a specific situation," the conversion of time will require time that "goes beyond universal life" to work.
Scientists have attempted to reverse the time for a scattered electron using an IBM quantum computer. For the experiment, scientists have used an "evolutionary program" that would influence the "cubits," also known as quantum bits. The quantum bit is the "fundamental unit of information in the quantum computer capable of existing in two states, 0 and 1, at the same time or at different times," according to Dictionary.com.
Here's how it works After starting the evolution program, the particles will move to a changing pattern of zeros and units. After this scatter, a program will change the state of the computer, allowing it to go back to its original state. Then the evolutionary model will again be launched from the second state and will return the cubes to their original state and past.
According to the team, in 85% of cases, the quantum two-cubic computer goes back to the original. condition. When three cubes were included in the test, more errors occurred and led to about 50% success. According to scientists, the error rate is expected to decrease when more devices are projected. With this experiment, turning over time can help make quantum computers more accurate in the future.
