Researchers have teleported quantum information across cities and even into space.Now, a team from Japan’s Yokohama National Un
iversity has managed something no one has ever done before. They teleported quantum information within a diamond — an achieveme
nt that could shape how we share and store sensitive information in the future.The sci-fi version of “teleportationö typically
involves taking some thing in one place and instantly having it show up in another. Quantum teleportation is a little different
as it involves taking information from one place and recreating it in another.This is possible thanks to quantum entanglement,
the strange connection that can exist between particles.When particles are entangled, we can look at one and know things about
the other, even if they’re separated by a great distance. Do something to one particle, and the other will reflect the action.
For their study, which was published in the journal Communications Physics on Friday, the Japanese researchers manipulated an e
lectron and a carbon isotope inside a diamond defect known as a nitrogen-vacancy center.To do this, they built an oscillating m
agnetic field around the diamond, then used microwave and radio waves to entangle the electron and the carbon atom’s nucleus.Af
ter the researchers had the electron absorb a photon holding quantum information, they saw the photon’s polarization state tran
sferred to the carbon — meaning they had successfully transported the quantum information.
