“Quantum technology is in a similar place — we have the idea and a sense of what we could do with it, and there are many competing platforms, but no clear winner yet,” he continued. “You have superconducting qubits, spin qubits in silicon, electrostatic spin qubits, and ion-trap-based quantum computers. Microsoft is trying to do topologically protected qubits, and in the Moody Lab, we’re working on quantum photonics.
Parto explained: “If we put these single photons into many different waveguides — a thousand single photons on each waveguide — and we sort of choreograph how the photons travel along the waveguides on the chip, we can do a quantum computation.” There are various ways to go about generating single photons, but Parto and his colleagues are doing it by using defects in certain two-dimensional semiconductor materials, which are only one“If you shine light onto the right kind of defect, the material will respond by emitting single photons,” Parto said, adding, “The defect in the material acts as what is called a rate-limiting state, which allows it to behave like a factory for pushing out single photons, one at a time.
Researchers try to do that in a couple of ways, for instance, by putting the material on the waveguide and then looking for an existing single defect, but even if the defect is precisely aligned and in exactly the right position, the extraction efficiency will be only 20% to 30%. That is because the single defect can emit only at one specific rate, and some of the light is emitted at oblique angles, rather than directly along the path to the waveguide.
In experiments using the micro-ring resonator that were done for this paper, the team achieved an extraction efficiency of 46%, which is an order-of-magnitude increase over prior reports.
