Scientists solve quantum puzzle and open the way to teleportation

New research has been able to measure W State, an innovation that can accelerate teleportation and quantum computing.

A new one published in Science Advances got a breakthrough in quantum physics when developing the first practical method for Identify and measure the statea form of quantum enthusiasting there is long unknown. The advance solves a puzzle of decades and can accelerate progress in teleportation and quantum computing.

Quantum entanglement, first described in 1935 by Albert Einstein, Boris Podolsky and Nathan Rosen in Famous Paradox EPRchallenges classical physics by allowing one particle to instantly affect another, regardless of the distance. Although Einstein has discarded him as “distance ghost action”, this phenomenon now supports next generation technologies, such as ultrasound communications, quantum networks and quantum computing.

Among the many forms of entanglement, the Greenberger-Horne-Zeilinger State (GHz) has been widely studied, but the state out of experimental reach. Traditional techniques had difficulty checking or measuring the state W, leaving a significant gap in quantum investigation.

This barrier has now been outdated. Exploring the cyclic displacement symmetry of the state state, the Japanese team has developed a new tangled measurement method using Photonic Quantum Circuits and Fourier’s quantum transform. Innovation allows scientists to identify W States in a single measurement, eliminating the need for repeated tests, says.

“More than 25 years after the initial proposal regarding tangled measurement for GHz states, we finally obtained the tangled measurement for state W, with genuine experimental demonstration for 3 photons W States,” he said, “he said Shigeki Takeuchicorresponding author of the study.

In experiments with three tangled photons, the device is reliable between different states, stablely operating for long periods with consistent accuracy. This reliability paves the way for new applications in both fundamental research and real -world technology.

The implications are long reach. By allowing precise manipulation of W States, the method may accelerate quantum teleport – The transfer of information without physical movement – and quantum computing based on measurements. Such capabilities are vital to the construction of inviolable communication networks, the advancement of simulations in medicine and climate science and the preparation of the land for a future quantum internet.

Takeuchi emphasized the broader importance of the discovery: “To accelerate research and the development of quantum technologies, it is crucial to deepen our understanding of the basic concepts to generate innovative ideas.”
