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
The paper investigates a one‑dimensional frustrated spin chain that combines cluster‑Ising and anisotropic next‑nearest‑neighbor Ising interactions, revealing two distinct quantum…
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…
Understanding Quantum Imaginary Time Evolution and its Variational form
Andreu Anglés-Castillo, Luca Ion, Tanmoy Pandit +3
Many computationally hard problems can be encoded in quantum Hamiltonians. The solution to these problems is given by the ground states of these Hamiltonians. A state-of-the-art al…
