It may be easier to develop scalable quantum computers and a “quantum internet” using silicon using existing technologies, thanks to a new study researchers at Simon Fraser University. a major breakthrough in quantum technology development, researchers describe their observations of silicon “T-centred” photonic spin qubits. According to the study, the research could help pave the way for the creation of massively scalable quantum computers as well as the infrastructure for the quantum internet.

Earlier, research showed that silicon could be used for some of the most and longest-lived qubits manufacturing. Unlike conventional computers, quantum computers use qubits to run multidimensional quantum algorithms. In addition, the development of quantum computers will also require communication technologies to help link qubits together on a larger scale.

The study, published the journal Nature, describes how T centers, a specific type of light-emitting defect in silicon, provide photonic links between qubits. “This work is the first a single T center has been measured individually, and indeed, the first time any single spin silicon has been measured optical measurements alone,” said Stephanie Simmons, Canada Research Chair Silicon Quantum Technologies.

Emitters like the T center, which combine high-performance spin qubits with photon generation, could facilitate the production of scalable and distributed quantum computers, Simmons explained. Simmons added that they can handle processing and communication simultaneously without the need for two different quantum technologies.

T-centers can come in handy because they emit light at wavelengths currently used in metro fiber optic communications and telecom network equipment. “With T-centers, you can build quantum processors that communicate inherently with other processors. When your silicon qubits can communicate emitting photons in the same wavelength bands used in data centers and fiber optic networks, you get connected quantum computing the same benefits of the millions of qubits required,” Simmons emphasized.

The researchers believe that touting a method of using silicon to create quantum computing processors would allow them to leverage existing knowledge and infrastructure, rather than developing a new industry for quantum manufacturing.
