RESTRICTIONS: Broadcast: NO USE JAPAN, NO USE TAIWAN Digital: NO USE JAPAN, NO USE TAIWAN A team from the Moscow Institute of Physics and Technology used a quantum system program to reverse the state of a quantum computer a fraction of a second into the past. They performed the experiments on two quantum bits, also known as qubits. Qubits are represented by a one, a zero or both at the same time. During the first stage of the experiment, the two qubits were unaltered. Then, scientists used a computer program to alter the order of the previous stage, causing the qubits to become a random assortment of ones and zeros. This process was followed by the time reversal stage during which the program reverses the chaotic effect on the qubits. Finally, the qubit reverts to the original state before it had been altered by the program. The program restored 85 percent of the cases where two qubits where involved. The team was able to create a state that evolved against the second law of thermodynamics, which states that the state of entropy in the universe increases over time. Changes of a state in a closed system can remain static but cannot be reversed. The paper was published in the journal Scientific Reports. RUNDOWN SHOWS: 1. Quantum system program 2. Qubits 3.

"According to the paper published in the journal Scientific Reports, they performed the experiments on two quantum bits, also known as qubits." "Qubits are represented by a one, a zero or both at the same time." "During the first stage of the experiment, the two qubits were unaltered. In the second stage, called 'degradation,' scientists used a computer program to alter the order of the previous stage, causing the qubits to become a random assortment of ones and zeros." "This process is then followed by the time reversal stage. At this time the program reverses the chaotic effect on the qubits. Finally, during the 'regeneration' stage, the qubit reverts to the same original state before it had been disrupted by the computer program." "The program was able to successfully restore 85 percent of the cases where two qubits where involved." "Through this program, the researchers were able to create a state that evolved against the second law of thermodynamics, which states that the state of entropy or disruption of the universe increases over time. Meaning that changes of a state in a closed system can remain static but cannot be reversed." "The researchers used the example of cue balls on a pool table. Imagine them formed in a pyramid shape at the center and then being hit, causing them to disperse." "Now imagine the process in reverse. The balls retrace the path they took when they were hit and return to the original triangular formation. This is similar to what the researchers accomplished with quantum bits."
