And secondly, the compatibility problem of the 5G and the existing communication network is that a 5G independent networking mode is adopted, and a network architecture, a base station and a core network are all rebuilt, so that the cost is high. Millimeter waves are electromagnetic waves with millimeter wavelengths, the frequency band is usually 30-300GHz, the frequency band is usually more than 24GHz, the 5G millimeter wave mobile communication technology has the advantages of high transmission rate, large bandwidth, low time delay and large-scale connection equipment, and the frequency band where millimeter waves are located can provide Sub-6GHz8 times, namely, the frequency band bandwidth reaching 800M, and can bring about 10Gbps connection rate. Meanwhile, the time delay of the millimeter wave technology is lower, and the positioning accuracy is higher. Therefore, when the railway wireless communication network is built, a vehicle-ground intelligent communication network edge cloud infrastructure is often built based on 5G millimeter waves, ultra-high quality service is provided based on deepening application of multi-access edge cloud computing of a 5G millimeter wave private network, and accurate coverage and distribution are performed in a high-flow area through deployment of millimeter waves, so that the problem of hot spot flow is effectively solved.

The millimeter wave dynamic ad hoc network has complex, heterogeneous, multidimensional, multi-state and other network characteristics, so that the quantum computation is hopeful to energize a communication system, and the capability of the quantum computation for high-dimensional data parallel processing and optimal solution parallel searching becomes one of kernel enabling technologies.

First, on the premise that the target component is known or solvable, a number of improved quantum search algorithms propose different strategies to increase the probability of obtaining the target component. However, these algorithms still cannot obtain the target component with 100% probability. Aiming at the problem, the information transmission system based on the integration of millimeter wave dynamic ad hoc network and ICT provides a multi-operator quantum search algorithm, which can ensure 100% success probability on the premise that a target component is known or can be solved, and specifically comprises the following steps:

1) Operator construction

The algorithm requires the use of two sets of operators, G and G'. The G operator is equivalent to the classical operator in the Grover algorithm. In the present algorithm, the G operator functions to raise the probability amplitude of the target component to a position close to 1. Then, the G 'operator is acted on the superposition state, the algorithm can obtain the target component with 100% probability, the internal structure diagram of the G' operator is shown in FIG. 6, it can be seen that the G operator is formed byOperator sum/>Operator composition, I represents the identity matrix,/>Expressed as projection operator，/>Representing a target component vector,/>Operator is represented as/>, by projection operator，/>Representing an equal weight superposition state vector.

Further, please refer to fig. 7,G' operator consisting of' Operator sum/>' Operator composition,/>Representing the identity matrix,/>Expressed as/>, by projection operator，/>Representing a target component vector,/>Operator is represented as/>, by projection operator，/>Representing an equal weight superposition state vector. /(I)The values of (2) can be solved according to the target component duty ratio, and the specific method is as follows.

2) Parameter determination

Let the search space have N total elements, where M are target elements,Is the duty cycle of the target component. Then, the parameters of the algorithm presented in this section give the G operator iteration number T, G ' operator iteration number T ' and the G ' operator phase angle/>, as follows. When a positive integer C is present such that:

（1.1）

If so, the value of the iteration times T of the G operator is shown in a formula (1.2).

（1.2）

Equation (1.2) can be considered as the theoretical number of iterations of the Grover algorithm, but T is not a positive integer in all cases. In fact, in most cases, T is not an integer. This is why the Grover algorithm cannot maintain a 100% success probability. When the positive integer C exists to enable the formula (1.1) to be established, the success rate of 100% can be achieved only by the G operator, so that the iteration times of the G 'operator are T' =0. Since in this case no iteration of the G 'operator is required, the G' operator phase angle need not take value.

When the formula (1.1) is established because the positive integer C does not exist, the iteration times T of the G operator are as follows:

（1.3）

FLOOR () in equation (1.3) is a downward rounding function, the number of G ' operator iterations takes T ' =1, G ' operator phase angle The values of (2) are as follows:

（1.4）

3) Description of the algorithm

In which there is provided a search spaceThe elements, fig. 8, give a schematic diagram of the algorithm presented in this section.

N-qubitI pass/>After the action, the equal-weight superposition state of N elements can be obtained and used as the initial state of operator iteration. Single qubit/>The superposition state/> isobtained after the H actionAs an auxiliary bit. From the above, T can be 0 or other positive integer, and T' can be only 0 or 1.

The multi-operator quantum search algorithm can obviously improve the resource utilization efficiency in a communication network and reduce the operation, maintenance, management and optimization cost in the telecommunication network for the capability of parallel processing of high-dimension data and parallel search of optimal solutions.
