US 2026/0074801 A1 · PHOTON NUMBER DETERMINATION USING REFRAMED TRACE DATA POINTS

Abstract

Systems, methods, and computer program products for determining a photon number. Electrical signal trace data is received by a signal processor. A plurality of trace data points are defined based on the received electrical signal trace data. Each trace data point includes both a signal value and a time value indicating the position of that trace data point within the electrical signal trace. The trace data points are input to a machine learning model trained to output predicted photon number data usable to determine the photon number corresponding to the received electrical signal trace. The machine learning model can be trained to output predicted photon number data based on an incomplete set of trace data points, and even individual trace data points. This can allow the photon number to be predicted when data is partially missing or lost, and/or before the entire electrical signal trace has been received.
