The team demonstrated an “unconditional teleportation” of quantum bits separated by a distance of three meters, Science Magazine reported.
“Realizing robust quantum information transfer between long-lived qubit registers is a key challenge for quantum information science and technology. Here, we demonstrate unconditional teleportation of arbitrary quantum states between diamond spin qubits separated by 3 m,” they said in their abstract, as cited by Science Mag.
“These results establish diamond spin qubits as a prime candidate for the realization of quantum networks for quantum communication and network-based quantum computing,” they added.
A separate article on The New York Times clarified that quantum teleportation is different from that seen on “Star Trek.”
In this case, it said it involves transferring quantum information, or the spin state of an electron, from one place to another “without moving the physical matter to which the information is attached.”
The researchers said they are now looking at doing the experiment with a longer distance – about one kilometer.
“If they are able to repeatedly show that entanglement works at this distance, it will be a definitive demonstration of the entanglement phenomenon and quantum mechanical theory,” the NYT said.
