Experimental Investigation of the One-Way Speed of Light Using Entangled Quantum Clocks

Determining the one-way speed of light without relying on prior assumptionsabout clocksynchronization remains a fundamental challenge in physics. Thismanuscript proposes an experiment toinvestigate this problem by measuring thetime-of-flight of a light pulse over a known distance using entangledquantumclocks as synchronized time references. This approach aims to potentiallycircumvent the conventionalityof clock synchronization inherent in classicalmethods. The experimental design emphasizes the generation anddistribution ofhigh-fidelity entanglement, continuous monitoring of the quantum clocks, andrigorous verificationof their temporal correlation through cross-correlationanalysis. While acknowledging the significant technologicalhurdles and thephilosophical complexities of defining absolute time, this study outlines anovel pathway towardsa potentially assumption-lean measurement of the one-wayspeed of light.
