Room-temperature atomic sensor using optical tweezers and piezo-driven quartz vibrations. FPGA + ESP32 hybrid control. No cryostat.
Fork on GitHubQuantum Fuse is now a **room-temperature quantum vibrometer** that detects mechanical vibrations using trapped neutral atoms in optical tweezers. We use a 1064 nm laser module, FPGA for trap modulation, ESP32 for DDS control, and a piezo-driven synthetic quartz plate as the vibration source. Inspired by the 6,100-qubit tweezer breakthrough, we’re coupling atomic qubits to mechanical modes—no cryostat needed.
Fork the repo, build the sensor, and help us push the limits of quantum sensing at room temp. ingen0s/quantumfuse
Example of an 823 mHz - 100 Hz pulse
The Q-Resonator now uses **optical tweezers at 1064 nm** to trap cesium atoms and **piezo-driven quartz** to induce vibrations. The FPGA modulates trap depth at 30 kHz, while the ESP32 drives the AD9851 for 10 Hz–10 MHz pulses. Scattered light from atoms shows Doppler sidebands at vibration frequency—quantum readout at room temp.

We're using **atomic fluorescence** from trapped atoms as the interference signal. The FPGA reads photodiode ADC at 1 MSPS, applies FFT, and detects vibration peaks. ML denoising runs on a PC to extract sub-nm motion from shot noise.

November 1, 2025: The ADR cryostat is **shelved** after the 6,100-qubit tweezer breakthrough proved room-temperature operation with 12.6 s coherence. We're now fully optical-mechanical hybrid—no LHe, no vacuum, no cryostat.
