The invention provides a quantum key distribution method and device and a computer readable storage medium, relates to the field of passwords, and can avoid long-time storage of quantum keys and improve the security of the quantum keys. The method comprises the following steps: acquiring a first request message; the first request message is used for requesting the first key demander and the second key demander to obtain the data keys respectively; the first request message comprises a first device identifier of a first key demander and a second device identifier of a second key demander, and generating a data key based on a quantum random number generator in response to the first request message; encrypting the data key based on a first key encryption key corresponding to the first device identifier and a root key to obtain a first encrypted data key; encrypting the data key based on a second key encryption key corresponding to the second device identifier and the root key to obtain a second encrypted data ke
