Investigation of Entanglement Through Circuit Geometry.
POSTER
Abstract
Quantum entanglement is a fundamental phenomenon that enables the connection of a large
number of qubits and serves as the backbone for quantum computing and quantum information
processing. Along with the coupling strength, the interaction between the qubits depends upon the
circuit geometry. This work deals with the longe range qubit-qubit interactions by analyzing
different structures of qubit lattices. Long-range cross-Kerr effercts are calculated to quantify the
correlations between the qubits[1]. We extend our work with calculations of correlations between
qubits using Mermin inequalities, providing deeper insights into the nature of quantum
entanglement[2,3]. The findings can help optimize quantum gate designs and improve error correction
protocols.
