Abstract
This paper explores the potential of utilizing entangled multi-body states for enhanced quantum simulation. Traditional quantum simulation methods face limitations when simulating complex quantum systems, primarily due to their inability to effectively represent multi-particle correlations. We propose a novel approach leveraging the inherent properties of entangled states to achieve a more accurate and efficient simulation of these systems. Specifically, we examine the construction of quantum computers incorporating multi-body entangled states and their application to simulating quantum field theories, a domain where complex many-body interactions are prevalent. The core idea centers on exploiting the correlations encoded within entangled states to reduce the computational complexity associated with simulating high-dimensional quantum systems. We present a theoretical framework outlining the key challenges and potential strategies for realizing this approach, focusing on the design of appropriate quantum circuits and the optimization of entanglement protocols. The ultimate goal is to demonstrate a pathway towards simulating intricate quantum phenomena that are currently intractable using conventional simulation techniques. The simulation method is based on mapping the problem to a quantum computer. The quantum computer performs the simulation based on the state of the qubits. The final result is the answer to the original problem. The key mathematical tool is the quantum circuit. The quantum circuit is a series of quantum gates applied to qubits. The quantum gates are unitary transformations. The unitary transformations are represented by matrices. The matrix is a square matrix. The matrix is a linear transformation. The linear transformation is a transformation that preserves linear relationships. The eigenvalues of the matrix are the solutions to the equation det(A - λI) = 0, where A is the matrix and λ is the eigenvalue and I is the identity matrix. The eigenvectors of the matrix are the vectors that are transformed to themselves by the matrix. The eigenvectors are the solutions to the equation (A - λI)v = 0, where A is the matrix, λ is the eigenvalue and v is the eigenvector. The eigenvalues and eigenvectors are important concepts in linear algebra.
