Abstract

The invention discloses a quantum decoherence degree detection method and device, electronic equipment and a computer readable storage medium. The method comprises the steps of determining an initialquantum state and a to-be-detected point of a to-be-detected quantum system; amplifying the amplitude of the quantum state of the to-be-detected point, and measuring the decoherence degree of the to-be-detected point; and calculating a decoherence coefficient of the to-be-detected quantum system according to the decoherence degree. According to the quantum decoherence degree detection method provided by the invention, the amplitude of the quantum state of the to-be-detected point in the to-be-detected quantum system is amplified, and the probability of the amplitude is measured to measure thedecoherence degree of the to-be-detected point. Meanwhile, the decoherence coefficient of the to-be-detected quantum system can be quantitatively calculated according to the measured decoherence degree. Therefore, the quantum decoherence degree detection method provided by the invention provides an effective quantum system decoherence analysis method.

Description

technical field [0001] The present application relates to the technical field of quantum computing, and more specifically, to a quantum decoherence degree detection method and device, an electronic device, and a computer-readable storage medium. Background technique [0002] Quantum computing is a new type of computing that uses quantum mechanical properties (such as superposition and entanglement, etc.) to perform operations. At present, it has been proved that quantum computing has computing power far exceeding that of classical computing in some fields. In quantum computing systems, information is stored in the form of qubits. Similar to classical bits, qubits also have states, which can be two ground states |0> or |1>, or a linear combination of |0> and |1>, called a superposition state. The quantum state is easily affected by the external environment, resulting in information distortion. A qubit in a superposition state becomes entangled with its surround...
