Diamonds are Forever

BRT has talked about quantum computers on several occasions as said devices are not only incomprehensively fast due to the superpostion of qubits but, more importantly, have the potential of creating reality in finite space, but before getting to that computing nirvana requires flawless quantum teleportation of information via entangled quibits, something not considered doable until now.

To date, scientists have struggled to use entanglement as a means of communication—it's been achieved but the error rate has been so great that it would be unfeasible as a real-world application. In this new effort, the researchers claim to have solved the error rate problem—they've brought it down to zero percent. They did it, they report, by trapping electrons in diamonds at very low temperatures and shooting them with lasers, resulting in the creation of qubits. The diamonds, the team reports, serve as really tiny prisons, holding the electrons in place. Held as they were, the researchers were able to cause a spin state to exist and then to read it at both locations, which meant that information had been conveyed.

Seen below is a short video showing how information can be processed via quantum teleportation.

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. We prepare the teleporter through photon-mediated heralded entanglement between two distant electron spins and subsequently encode the source qubit in a single nuclear spin. By realizing a fully deterministic Bell-state measurement combined with real-time feed-forward quantum teleportation is achieved upon each attempt with an average state fidelity exceeding the classical limit. These results establish diamond spin qubits as a prime candidate for the realization of quantum networks for quantum communication and network-based quantum computing.
