Beijing time on October 4, 2022 at 17:45, Beijing time, the 2022 Nobel Prize in Physics was announced. Quantum physicists from France, the United States and Austria, (Alain Aspect), John Clauser, , and Anton Salinger, (Anton Zeilinger), respectively, won the award.
Reason for winning the award:
commended them for "using entangled photons to conduct experiments, proving that Bell inequality is not true, and pioneering quantum information science ".

Through the article, we can understand Professor Salinger's outstanding contribution to the field of quantum communication and is infected by his passion for scientific research.
Anton Salinger
Anton Salinger, who calls himself a "family modern technology user", walked into the office, with a small folding bicycle in his arms, and a motor was installed on the car. After taking off the helmet, he was smiling and energetic, and his hair and beard were white.
This Austrian quantum physicist in his seventies is the dean of Austrian Academy of Sciences and also teaches in University of Vienna, MIT , Innsbruck University and other universities.
It is worth mentioning that his former student Pan Jianwei began to conceive the "Mozi" during his graduate school degree at Innsbruck University, and together with his teacher, he proposed the pioneering quantum transmission solution. Finally, twenty years later, he led the team to develop the world's first quantum satellite.
Salinger has an obsessive-compulsive fanaticism about quantum technology. Over the past few decades, he has focused on quantum computer , quantum cryptography and quantum teleportation, trying to touch and even control the "ghostly ultra-distance effect" between particles, namely quantum entanglement.
In his opinion, although this kind of ghost effect in Einstein's has been questioned, it will eventually form the basis of future technology. At that time, data will no longer be transmitted between devices through traditional methods (such as radio), but will be based on quantum entanglement and transmitted in quantum state , which is like a ghost, safe and anti-epit.
997, Salinger's team realized quantum stealth transmission for the first time. In 2007, an international team led by Salinger set a record of 144 kilometers of the farthest quantum communication distance at that time. By 2017, the Mozi satellite led by Pan Jianwei will push the limit of quantum stealth transmission to 1,200 kilometers.The Institute of Quantum Optics and Quantum Information of the Austrian Academy of Sciences (IQOQI), led by Salinger, is one of the halls of quantum research worldwide. However, according to Claudia Heindler, a young woman with ambition, “it’s colder than space.”
Because IQOQI's laboratory is not studying photon , but atom - an quantum gas composed of about one million atoms is produced in an environment that is only one little higher than absolute zero (-273 degrees Celsius).
Salinger once recalled his mood when he first met quantum physics: at that time he was still a student, and encountered quantum physics that could hardly be understood by common sense, "and became fascinated at once", and then he was so crazy that he ignored all lectures and devoted himself to the quantum-related documents at hand. Salinger compares the current application of quantum technology to the first microchip 50 years ago: "No one had any idea about the iPhone at that time," said Cornelius Hempel, a researcher at the University of Innsbruck. "Even the strongest supercomputers are difficult to simulate anything but the simplest chemistry, and quantum computers that simulate nature provide a new way to understand matter." It may have unprecedented effects on medicine and may also change materials science.
