Abstract

The present application discloses a method for erasing quantum data, including: obtaining an equal-probability quantum state system; measuring the equal-probability quantum state system so that the equal-probability quantum state system collapses into a binary random number sequence; generating a corresponding The random angle value; according to the random angle value, the quantum data in the quantum device is rotated bit by bit to complete the erasure of the quantum data. This application introduces quantum true random numbers, which can ensure that the data after erasing will not be restored and will not be reversely cracked, which is of great value to the protection of data assets; at the same time, the data after random processing still has quantum coherence, quantum Features such as entanglement can be used in the future, avoiding the time-consuming and labor-intensive process of re-preparing the quantum system every time. The present application also provides a system, device and readable storage medium for erasing quantum data, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of quantum data, in particular to a method, system, device and readable storage medium for erasing quantum data. Background technique [0002] Quantum computer is a kind of physical device that follows the laws of quantum mechanics to perform mathematical and logical operations, store and process quantum information. In a quantum computer, the basic unit of information is a quantum bit (Qubit), and the object of operation is a sequence of qubits. Unlike the bits of a classical computer, a sequence of qubits is not a specific value consisting of 0 or 1, but a superposition state between the two. These special quantum states not only provide the possibility of quantum parallel computing, but also bring some properties to quantum computing that make classical computing unmatched. [0003] Quantum systems are a limited resource and are not easy to prepare. Therefore, in the process of computing, it is inevita...
