Researchers from Simon Fraser University may have just released the photonic springs that accelerate the quantum internet. In a paper published in Nature (opens in new tab), the researchers demonstrated an emergent capacity in silicon qubits to produce a “photonic link” between each other. Furthermore, this same photonic capability may be easily integrated with the existing fiber optic infrastructure that already carries data across a reasonable (yet still insufficient) portion of society. That is bound to provide immense savings on deploying a quantum internet – and as we all know, the cost is (mostly) king.

The authors’ paper describes observations carried on particular types of qubits: “T-center” photon-spin qubits, a kind of qubit that takes advantage of a specific luminescent defect in silicon – more specifically, InGaAs (Indium gallium arsenide), also explored in CPU manufacturing technologies. Silicon qubits have already shown remarkable coherence times – which relate to how resistant qubits are to outside interferences that would cause them to collapse and lose their information in the process, becoming unusable for the workload at hand.
