Method and Apparatus for Measuring Time

This abstract first appeared for US patent application 20240411273 titled 'Method and Apparatus for Measuring Time

Original Abstract Submitted

a method and apparatus for measuring time, and a programmable controller for a quantum communication device are provided. the method includes: receiving a start signal and a stop signal; sampling the start signal and the stop signal by using a same clock to generate a start bit string corresponding to the start signal and a stop bit string corresponding to the stop signal; extracting a rising edge of the start signal from the start bit string, and extracting a rising edge of the stop signal from the stop bit string; and determining a time interval between the start signal and the stop signal based on a count of bits between the rising edge of the start signal and the rising edge of the stop signal and based on a period of the clock.
