- Abstract summary: Quantum photon sources of high rate, brightness, and purity are increasingly desirable as quantum information systems are quickly scaled up and applied to many fields.
Using a periodically poled lithium niobate microresonator on chip, we demonstrate photonpair generation at high rates 8.5 MHz and 36.3 MHz using only 3.4-$mu$W and 13.4-$mu$W pump power.
The measured coincidence to accidental ratio is well above 100 at those high rates and reaches $14,682pm 4427$ at a lower pump power.

- Abstract: Quantum photon sources of high rate, brightness, and purity are increasingly
desirable as quantum information systems are quickly scaled up and applied to
many fields. Using a periodically poled lithium niobate microresonator on chip,
we demonstrate photon-pair generation at high rates of 8.5 MHz and 36.3 MHz
using only 3.4-$\mu$W and 13.4-$\mu$W pump power, respectively, marking orders
of magnitude improvement over the state-of-the-art. The measured coincidence to
accidental ratio is well above 100 at those high rates and reaches $14,682\pm
4427$ at a lower pump power. The same chip enables heralded single-photon
generation at tens of megahertz rates, each with low auto-correlation
$g^{(2)}_{H}(0)=0.008$ and $0.097$ for the microwatt pumps. Such distinct
performance, facilitated by the chip device's noiseless and giant optical
nonlinearity, will contribute to the forthcoming pervasive adoption of quantum
optical information technologies.
