Quanta microscopy enables fluorescence imaging at the native bit-plane rate

Quanta microscopy (QM) converts sparse single-photon bit planes into multibit grayscale fluorescence sequences at the native 50 kHz sensor cadence, without temporal binning.

• Why it matters: Live-cell fluorescence imaging is limited by photon budgets and exposure-integrated detection, forcing a trade-off between temporal sampling and image quality.
• What they did: QM uses high-speed single-photon acquisition and self-supervised spatiotemporal reconstruction to transform binary photon-detection maps (bit planes) into one output frame per bit plane.
• The result: QM enables rapid quantitative imaging across specimens, including beating hiPSC-derived cardiomyocytes and electrically stimulated calcium-response transients in primary cortical neurons, under photon-limited conditions.
