Vernier Microcombs for Integrated Optical Atomic Clocks
Kaiyi Wu, Nathan P. O'Malley, Saleha Fatema +8
CMOS-compatible Kerr microcombs have drawn substantial interest as mass-manufacturable, compact alternatives to bulk frequency combs. This could enable deployment of many comb-reli…
Architecture for Integrated RF Photonic Downconversion of Electronic Signals
Nathan P. O'Malley, Keith A. Mckinzie, Mohammed S. Alshaykh +5
Electronic analog to digital converters (ADCs) are running up against the well-known bit depth vs bandwidth tradeoff. Towards this end, RF photonic-enhanced ADCs have been the subj…
Complete frequency-bin Bell basis synthesizer
Suparna Seshadri, Hsuan-Hao Lu, Daniel E. Leaird +2
We report the experimental generation of all four frequency-bin Bell states in a single versatile setup via successive pumping of spontaneous parametric downconversion with single…
Nonlocal subpicosecond delay metrology using spectral quantum interference
Suparna Seshadri, Navin Lingaraju, Hsuan-Hao Lu +3
Timing and positioning measurements are key requisites for essential quantum network operations such as Bell state measurement. Conventional time-of-flight measurements using singl…
High-dimensional discrete Fourier transform gates with the quantum frequency processor
Hsuan-Hao Lu, Navin B. Lingaraju, Daniel E. Leaird +2
The discrete Fourier transform (DFT) is of fundamental interest in photonic quantum information, yet the ability to scale it to high dimensions depends heavily on the physical enco…
Bell state analyzer for spectrally distinct photons
Navin B. Lingaraju, Hsuan-Hao Lu, Daniel E. Leaird +3
We demonstrate a Bell state analyzer that operates directly on frequency mismatch. Based on electro-optic modulators and Fourier-transform pulse shapers, our quantum frequency proc…
