A joint research team from Japan has observed electrons called “heavy fermions,” which have a mass many times greater than normal. These have been found to be involved in quantum entanglement.
2. Entanglement under the control of Planckian time:
These heavy electrons show entanglement under a special quantum time unit—Planckian Time—which is considered the most fundamental unit of time in quantum mechanics.
3. Path to a new generation of quantum computers:
This discovery has indicated that by controlling entanglement in solid-state materials, a new type of quantum computer can be created in the future.
4. The study focused on CeRhSn:
A material called Cerium-Rhodium-Tin (CeRhSn) was used in the research, in which heavy fermions were found. The material exhibits a quasi-Kagomé lattice structure, which is known for its geometrical frustration.
5. Non-Fermi Liquid behavior confirmed:
Spectra measurements of CeRhSn showed that the material does not exhibit conventional electronic behavior but rather non-Fermi liquid behavior, and that too around room temperature.
6. Entanglement revealed by spectra:
The reflectance spectra of the material showed that the heavy electrons can be described by the same mathematical function—that is, they are quantum entangled with each other.
7. Discovery led by Dr. Shin-ichi Kimura:
The research was led by Dr. Shin-ichi Kimura of Osaka University. He said, “Our discovery shows that these heavy fermions are indeed entangled and this entanglement is governed by Planckian time.”
8. Hope for a new revolution in quantum computing:
If such entangled states can be controlled in stable materials, it could bring a new revolution to quantum computing. This could make faster and more secure data processing possible.
9. Scientific leadership of Osaka University:
Osaka University, founded in 1931, is one of Japan’s premier national universities. This discovery is part of the tradition of innovation that the university works to bring from science to technology.
10. Foundation for future technologies:
This research has not only improved the understanding of heavy electrons, but this discovery can also form the foundation of the next generation of quantum technologies—such as superconducting computers, ultra-fast chips and secure communication networks.
