New Japanese quantum battery promises to transform the market, reducing charging time from 10 hours to just seconds, in addition to offering several other benefits.
Japanese scientists have created an innovative quantum battery that uses the principle of superposition to recharge. It is cutting edge technology, exploiting quantum phenomena, promises to surpass conventional batteries in terms of performance and durability. This discovery is attracting the interest of several companies and universities, driving significant studies and research in the area, and already demonstrating considerable advances.
Understand the main benefits behind the new Japanese quantum battery
For the first time, researchers from Tokyo University explored a new quantum process, which ignores the conventional notion of causality, to further improve the performance of these batteries and take another step towards the possibility of adopting them in the real world. However, to make things clear, the word quantum, that is, the physics that governs the subatomic world, now has several applications.
From computers, which are talked about a lot, to batteries, in fact. In this field, technology makes it possible to create highly efficient products with very low energy consumption. The new Japanese battery has the advantage of recharging quickly, even when little energy is available.

A study of the Center for Theoretical Physics of Complex Systems at the Institute of Basic Science (IBS) in South Korea estimates that the Charging a quantum battery is 200 times faster than normal, reducing, for example, a 10-hour recharge to just 3 and a half minutes. In the case of an ultrafast station, this time would drop to just 9 seconds.
The quantum battery is currently being developed and, according to the Professor Yoshihiko Hasegawa, from the Department of Information and Communication Engineering at the University of Tokyo, together with several students and researchers, focused their work on studying the best way to charge a quantum battery, since there is more than one.
Japanese battery can be charged using optical devices
According to Yuanbo Chen, one of the students involved in Hasegawa's work, batteries currently use chemicals such as lithium to store energy. A quantum battery works according to a different logic.
Chemical batteries are governed by the laws of classical physics, while microscopic particles of a quantum nature follow others, offering the possibility of exploring innovative ways of using them.
Researchers in Japan were particularly interested in how quantum particles might work to overcome their beliefs in one of their most deeply held experiences, that of time.
In collaboration with researchers from the Beijing Computational Science Research Center, the Japanese team attempted to charge a quantum battery using optical devices such as lasers, lenses and mirrors, exploring, above all, an innovative method.
Discover the new innovative method for charging the Japanese battery
In general, to charge a quantum battery, we proceed through successive steps placed in an exact order. This happens because randomness, in these fields, follows a defined path in which a certain event (A) is followed by a second (B) and then by a third (C) and so on.
The team from Japan, on the other hand, used a new quantum effect that they called indefinite causal order (ICO), which allows the randomness of events to proceed in both directions. From A to B, but also from B to A, in a principle known as quantum superposition.
For Chen, with ICO, the team showed that the way a battery made up of quantum particles is charged can drastically affect its performance. Huge gains were also observed in both the energy stored in the system and thermal efficiency.
In this somewhat counterintuitive way, the surprising effect of an interaction was discovered that is the opposite of what one might expect: a low-power charger can deliver more energy with greater efficiency than a higher-power charger, being used by the same device.
