On July 1, 2024, PHYSICAL REVIEW LETTERS published "Observing the Quantum Mpemba Effect in Quantum Simulations" [1],[2]. The paper describes the Quantum Mpemba Effect, which was first observed experimentally by a team from the Austrian Academy of Sciences. It reveals that under certain conditions, a tilted ferromagnet recovers its symmetry more quickly when it is far from its symmetric state than when it is close to it. This phenomenon is of great interest in physics because it has similarities to the classical Mpemba effect, whereby under certain conditions the path a system takes to reach its final state may be the opposite of what is normally expected.  1, 2024,The discovery of the quantum Mpemba effect not only enriches our understanding of the behavior of quantum systems, but also provides a new physical basis for the development and application of quantum technology.

In fact, I have already proposed the quantum Mpemba Effect in the Mpemba Effect- the Effect of Time preprint [3] published on scienceopen on October 5, 2021, and in the article [4] officially published on May 5, 2022, namely: The higher the blackbody temperature, the shorter the time it takes for the blackbody to cool down to equilibrium. Because a blackbody is a system composed of a large number of light quanta. The higher the temperature of the blackbody, the higher the average energy (frequency) of the constituent quanta, meaning that the quantum system of the blackbody is further away from equilibrium state. Therefore, the article has pointed out that quantum systems have the Mpemba effect, and used this to explain why quasars have very short lifetimes, why stars with larger mass (higher temperature) have shorter lifetimes, and the classical Mpemba effect. In other words, the article has published the quantum Mpemba effect. 

This paper also gives the principle of the "quantum Mpemba effect," which states that: quantum systems must release energy (quantum) when returning from a state of deviation from equilibrium to equilibrium. The further the quantum system deviates from equilibrium, the higher the energy (frequency) of the quantum released and the shorter the time for quantum transition, the faster the intrinsic time of the quantum system, and therefore the shorter the lifetime of the quantum system. If the quantum jump such as a person jumping off a building, then the higher the floor of the person landing first, this is the quantum time effect (this is proposed by me according to the nature of time is energy flow). The higher the blackbody temperature, the higher the floor distribution of all the jumpers, so the shorter the time it takes for all the jumpers to land. This is how the "quantum Mpemba effect" works.

I designed a quantum Mpemba effect experiment with low requirements for experimental equipment, small investment and easy to do: two identical metal rods are electrically heated to different temperatures in a vacuum chamber. After the heating is stopped at the same time, the temperature drop rate of the two metal rods is measured respectively until the temperature of the two metal rods returns to the equilibrium temperature (room temperature).

 Verification:

1. The high temperature metal rod reaches the equilibrium temperature before the low temperature metal rod.

2. 

where t is the time , T is the absolute temperature of the metal rod.

It is hoped that the scientific research units that have the conditions to do this experiment will do this experiment.
