For the first time, scientists successfully performed quantum teleportation between two chips

We don’t fully understand quantum mechanics or quantum entanglement (something Albert Einstein called “paranormal activity from afar”), yet we can still apply it to achieve technological breakthroughs, that’s great. ! Right on the last day of last year, scientists achieved a new achievement: for the first time, they were able to successfully quantum teleport between two computer chips.

This breakthrough means that scientists have been able to transmit information between two chips without wires, taking advantage of quantum entanglementlinking two particles together so that data can be transmitted through the air. Although this success has only happened in the laboratory, there is no denying the potential of a new breakthrough.

Scientists have taken advantage of quantum entanglement – linking two particles to be able to transmit data through the air.

“Under laboratory conditions, we were able to demonstrate a high-quality quantum entangled bond between two chips, two photons in two separate chips exhibiting the same quantum state,” the physicist Quantum physicist Dan Llewellyn from the University of Bristol, UK. “ Each chip is programmed to perform a series of tasks, taking advantage of the particle’s quantum entanglement.

In theory, two particles could be quantum entangled with each other no matter how far away, at two chips a few meters apart or at the ends of the Universe. Once they are entangled, it is only necessary to determine the state of one particle to know the state of the other.

To achieve this breakthrough, the team created multiple pairs of entangled quantum photons, encoding quantum information into them, ensuring that the information was accurate and did not affect the quantum state of the particle.

“The flagship test is when we do the teleportation of information between two chips, where the quantum state of a particle is transferred between the two chips as soon as we make a quantum measurement,” said Professor Llewellyn speak.

Subsequent testing by the team showed that the information was 91% accurate.

Increasingly, we see more and more breakthroughs in quantum informatics, more specifically finding ways to take advantage of quantum entanglement, but the essence of it remains the same: it is very difficult to manipulate quantum entanglement to your liking. . Systems that operate signal transmission through quantum entanglement are still cumbersome, not to mention expensive.

But then breakthroughs like today’s research make us excited for a quantum future: when everyone can have quantum computing power in their hands, surf the web on a completely secure Internet. , transmit signal without interference.

The new research also helps quantum physics to embrace the silicon chip technology that is found in all electronics.

“In the future, just a silicon chip with a quantum photon device, using the same control technology as in a classical computer, will open the door to a quantum communication and information processing system. believe “, said quantum physicist Jianwei Wang, who is working at Peking University.

The study was published in the journal Nature Physics.
