Patent ID: 11982697

Abstract:
The application discloses a RF vector measurement system including: a first port for generating a RF pulse, a pulse splitter for splitting the pulse into a first pulse send to a device-under-test DUT, and a second pulse send as a reference to a first quantum sensor of the system. The system is arranged to supply a third pulse, which is produced by reflecting or transmitting the first by the DUT, to at least one second quantum sensor phase-correlated with said first quantum sensor by entanglement. A computing unit is arranged to perform a measurement of the DUT by: reading out the state of the population of the first and the second quantum sensor, wherein the state of the second quantum sensor is based on the relative phase and relative amplitude of the second pulse and the third pulse, and determining the relative phase and relative amplitude of the second pulse and the third pulse as the closest match when applying a quantum sensor model for the second quantum sensor, the model being designed to model the dependencies between the relative phase and amplitude and the resulting population state.
