Abstract
A quantum data erasure method, system and device, and a readable storage medium. The method includes: acquiring an equal-probability quantum state system; measuring the equal-probability quantum state system to collapse the equal-probability quantum state system into a binary random number sequence; generating a corresponding random angle value according to the binary random number sequence; and performing a bitwise rotation operation on quantum data in a quantum device according to the random angle value to complete this quantum data erasure. In the present application, the introduction of a quantum true random number can ensure that erased data will not be recovered and reversely cracked, and is of great value in protecting data assets; moreover, randomly processed data still has the characteristics such as quantum coherence and quantum entanglement, and can be used in subsequent operations, whereby a time-consuming labor-intensive process of preparing a quantum system is not required every time.
