Emergence of a Macroscopic Cat State and Multi-Channel Entanglement in a Frustrated Cluster Spin Chain
Mohit Lal Bera, Andreu Anglés-Castillo, Alberto Acevedo Meléndez +8
We study a one-dimensional frustrated spin chain, which combines cluster-Ising and anisotropic next-nearest neighbor Ising models. We first offer a historical perspective that just…
Entanglement Transfer Dynamics in a Two-Leg Spin Ladder Under a Selective Magnetic Field
Soghra Ghanavat, Abbas Sabour, Somayeh Mehrabankar
We investigate the dynamical transfer of bipartite entanglement through a two-leg spin-1/2 ladder governed by the anisotropic Heisenberg (XXZ-type) model with a selective magnetic…
Dynamical Evolution of Quantum Correlations and Decoherence in Coupled Oscillators Interacting with a Thermal Reservoir
Somayeh Mehrabankar, Farkhondeh Abbasnezhad, Davood Afshar +1
We investigate the dynamical evolution of quantum discord, entanglement and purity in an open quantum system of two coupled asymmetric harmonic oscillators interacting with a therm…
Adaptive time Compressed QITE (ACQ) and its geometrical interpretation
Alberto Acevedo Meléndez, Carmen G. Almudéver, Miguel Angel Garcia-March +8
Imaginary time evolution (ITE) is a well-established method for ground-state preparation, a fundamental problem in many fields such as materials science, chemistry, and optimizatio…
The effect of noisy environment on Secure Quantum Teleportation of uni-modal Gaussian states
Somayeh Mehrabankar, Payman Mahmoudi, Farkhondeh Abbasnezhad +2
Quantum communication networks can be built on quantum teleportation, which is the transmission of an unknown quantum state from a sending station to a remote receiving station sup…
Reducing the number of qubits in quantum simulations of one dimensional many-body Hamiltonians
Somayeh Mehrabankar, Miguel Ángel García-March, Carmen G. Almudéver +1
We investigate the Ising and Heisenberg models using the Block Renormalization Group Method (BRGM), focusing on its behavior across different system sizes. The BRGM reduces the num…
