Description
Technical Field
The invention belongs to the field of quantum computation, in particular relates to a program language description system based on a quantum circuit model, which is a low-time and space complexity system for simulating a quantum circuit by a computer.
Background
A quantum algorithm described in a quantum wire model is a method of manipulating a quantum computer to process input states and output specific measurement values. Quantum computers are a key technology under study when running quantum algorithms because they have the ability to handle mathematical problems more efficiently than ordinary computers, for example, the time to break RSA keys can be accelerated from hundreds of years to hours. The processing speed of a quantum computer increases exponentially with the number of quantum bits, and it is expected that above 50 bits, the processing speed of a quantum computer on a particular problem will be faster than the sum of the processing speeds of all supercomputers in the world. However, the prototypes of quantum computers at present have a small number of qubits, and the actual processing speed is not as fast as that of classical computers. In order to solve the problem, people predict the behavior of the quantum computer by using a theoretical analysis method, and the method is usually used for verifying the correctness of the behavior of the quantum algorithm or the quantum computer and guiding the design of the quantum algorithm and the quantum computer.
In the past, the change of quantum state was analyzed and simulated by using the product of a unitary transformation matrix representing a quantum logic gate and a complex vector representing the quantum state. However, the time and space complexity of such calculation increases with the number of qubits by a quadratic exponential function, and when the qubits reach 20 bits, the matrix dimension required for representing one quantum logic gate reaches 1048576, and for example, a double-precision floating-point data type requires 16384GB of memory for storage, which occupies a huge storage space. In addition, quantum algorithms are described by using a quantum circuit diagram, and the method has the defect of poor expandability.
Disclosure of Invention
1. Problems to be solved
Aiming at the problem that in the prior art, the quantum line cannot be calculated due to the fact that a storage space is too large for matrix operation, or the quantum line cannot be simulated due to the fact that the storage space is enough but the calculation time is too long, the invention provides a low-complexity simulation system for simulating the quantum line. The invention utilizes the implicit internal rule of the quantum logic gate to directly operate the matrix elements of the quantum state vector, and meanwhile, the method has expandability and can use a super computer to simulate a quantum computer with more bits in the future.
2. Technical scheme
In order to solve the above problems, the present invention adopts the following technical solutions.
The invention principle is as follows: and reducing the complex redundant matrix multiplication into a plurality of low-dimensional matrix multiplications by using the matrix characteristics of the quantum logic gate.
A low-complexity quantum wire simulation system comprises an input module, a data processing module and an output module, wherein the data processing module processes data as follows:
(1) establishing a mathematical model to characterize quantum states and quantum logic gate operations
For single-quantum bits, the mathematical model is a 1 x 2 complex vector; for N qubits, by direct product operationCalculating to obtain 1 x 2NA complex vector of (a); using two 1 x 2NDimensional vectors which respectively store the real part and the imaginary part of a quantum state and represent the corresponding quantum logic gate by any given quantum logic gate U and bit number of operation;
