Revolutionizing Entanglement Quantification: How Deep Learning Outperforms Traditional Methods with Limited Data

The amount of entanglement in a system depends on a variety of factors, like the randomness of a system and the coefficient of entanglement. This property of a system is defined by a specified number demonstrated or predicted using Machine Learning or a Deep Learning algorithm. Recent years have brought a significant development in the process of entanglement of a system. It has wide applications diversified across many domains. The main focus of the problem statement is to measure the degree of entanglement of the system, which is its coefficient. However, the problem is that measuring the quantum state of a system vanishes the degree of entanglement achieved through the process.

To solve this problem statement, a group of research scholars developed several copies of these multiple quantum states. The degree of entanglement is measured for every quantum state. This method ensures an accuracy of almost 100% and a good F1 score. It requires quite high computing power. This technique is called quantum tomography. This method is quite tedious if we try to solve this problem statement using our old Machine Learning approach. Therefore, researchers tried to solve this problem statement using an educated number of guesses. This approach was through the help of Deep Learning neural networks. This approach involves passing the Data or measurement description across the deep layers. The maximum likelihood algorithm is used in neural networks to obtain quantum correlations as the output. These quantum correlations are also called Determined quantum correlations.

This Deep Learning approach improved the precision and recall values to a large extent. The research team used this approach to measure the degree of entanglement of a system rather than measuring it directly. This approach provided quite satisfactory results. The AI app was also generated using the following approach, which was deployed later. This app was trained to study the entangled quantum states using the numerical data which represented the degree of entanglement of the system. This model was trained using a large number of epochs and a significant learning rate, which resulted in more precise results with each run.

The researchers tested this AI app model using a dataset about the degree of entanglement of a system. The testing results showed that the error rate fell to 90% of its present value. The research scholars also tested the model again in the real world environment. The results were almost the same, and the same scope of improvements were shown, which were shown with the simulated data. The results were published officially via research paper, and the error rate was also reduced to some extent.
