In the strange world of quantum physics, even the tiniest tweak can unlock outsized rewards.
In a new study, scientists have shown that simply swapping one type of hydrogen atom for a slightly heavier version inside silicon can make it dramatically better at producing single photons.
This may sound like a minor chemical adjustment, but it could have major consequences for quantum computers and ultra-secure communication networks.
“Efficient single-photon emitters are desirable for quantum technologies, including quantum networks and photonic quantum computers,” the study authors
The study challenges the long-held belief that silicon is an inefficient host for quantum light sources. Instead, it shows that silicon, which is already the backbone of modern electronics, may also power the quantum internet of the future.
