How Our Single-Photon
Vibrometer Works
QCI’s quantum-accelerated Quantum Photonic Vibrometer is used to measure surface vibrations. It’s also compatible with current classical measurement techniques to enhance existing approaches.
The technique works by using a special type of sensor that can detect single photons. It measures changes in the number of photons as the target surface is slightly moved or tilted. By using pulses of light with a specific repetition rate, the system captures variations in photon counts over a certain time period. This data is processed to convert the measurements into a time-series of photon counts.

Technical Description
Quantum Photonic Vibrometer (QPV) is a remote displacement and vibration sensing technique that detects ultra-weak backscattered optical signals at the single-photon level. It uses a Geiger mode Avalanche Photodiode (APD) to directly count these signals. Unlike traditional systems, QPV is suitable for low-flux applications where the number of returning photons is much less than one per probe pulse. The system operates with 50 MHz pulses, and variations in photon counts are integrated over a preset dwell-time (∆t) using a field-programmable-gate-array (FPGA). The FPGA-generated time-series measurements, which eliminate the need for complex analog detection systems, are transmitted via Ethernet to a computer for further analysis. Quantum Photonic Vibrometer can detect mechanical displacements down to 110 nm and resolve vibration frequencies from DC up to 4 kHz with less than 0.01 detections per pulse.
The QPV setup includes a mode-lock laser producing 6 ps pulses at a 50 MHz repetition rate, an InGaAs APD for time-gated detection. A fiber optics circulator separates outgoing signal pulses from backscattered photons. The system employs a monostatic coaxial transceiver configuration with off-the-shelf optical components, such as a single-mode fiber (SMF) and an aspheric lens for collimation. The coaxial design eliminates the need for precise alignment when the target distance changes. The low numerical aperture of the SMF acts as a spatial filter, making the transceiver sensitive to spatial and angular changes in the returning signal caused by target movement. Quantum Photonic Vibrometer overcomes the limitations of intensity-based vibration sensors, achieving single-photon sensitivity for remote sensing and offering potential for advanced digital signal processing techniques for noise mitigation and analysis.
