1. It is based on the principle of quantum mechanics and is used to realize the storage and processing of information.
2. Quantum-level chips use qubits to replace binary bits in traditional computers, and use properties such as quantum superposition and entanglement to process information.
Quantum superposition allows qubits to be in multiple states at the same time, while entanglement makes the states between multiple qubits related to each other.
The principles of quantum chip include quantum superposition, quantum entanglement, quantum measurement, etc.
By precisely controlling and operating qubit, applications such as quantum computing and quantum communication can be realized. 3. The principle of quantum-level chips extends to quantum computing, quantum communication and other fields.
Quantum computing has parallel computing capabilities that allow for exponential acceleration on some specific problems.
Quantum communication can achieve absolutely secure information transmission. With the development of quantum technology, the principle and application of quantum chips will be further expanded, and it is expected to play an important role in the field of information science and technology in the future.
The working principle of quantum chips can be divided into two parts: the preparation of qubits and the operation of qubits. The preparation of qubits is achieved by placing a quantum system in a superposition state. This quantum system can be an atom, an ion, or a superconducting qubit. In the process of preparing qubits, the quantum system needs to interact with a control system so that the quantum system is in a superposition state. The control system can be a laser or a microwave pulse.

The operation of qubits is achieved by performing unitary transformations on qubits. Unitary transformation is a transformation that keeps the amplitude and phase of the quantum state unchanged.
