Operator folding and matrix product states in linearly-coupled bosonic arrays
Keywords:
Quantum simulations, bosonic systems, entanglementAbstract
A protocol to obtain the matrix product state representation of a class of boson states is introduced. The proposal is presented in the context of linear systems and is tested by performing simulations of a reference model. The method can be applied regardless of the details of the coupling among modes and can be used to extract the most significant contribution of the tensorial representation. Characteristic issues as well as potential variants of the proposed protocol are discussed. Se introduce una técnica para obtener la representación en términos de productos de matrices de una clase de estados bosónicos. La técnica se presenta en el contexto de sistemas lineales y se verifica realizando simulaciones de un sistema conocido. Este método se puede aplicar independientemente del tipo de acoplamiento entre modos y se puede usar para extraer la parte mas significativa de la representación tensorial del estado. Se discuten tando las características mas importantes como las posibles extensiones de la propuesta.Downloads
