Classical chaos arises from the inherent non-linearity of dynamical systems. However, quantum maps are linear; therefore, the definition of chaos is not straightforward. To address this, we study a quantum system that exhibit chaotic behavior in their classical limits. One such system of interest is the kicked top model [Haake, Ku ́s, and Scharf, Z. Phys. B 65, 381 (1987)][1], where classical...
Bell's inequalities provide a practical method for testing whether correlations observed between spatially separated parts of a system are compatible with any local hidden variable description. For $2-$ qubit pure states, entanglement and nonlocality as measured by Bell inequality violations are directly related. However, for multiqubit pure states, the much more complex relation between...
Among the different approaches to studying the structure of atomic nuclei comprising protons and neutrons, the nuclear shell model formalism is widely successful across different regions of the nuclear chart. However, applying the shell model formalism becomes difficult for heavier mass regions, as the Hilbert space needed to define such a problem scales exponentially with increasing number of...
Many-body entanglement is essential for most quantum technologies, but generating it on a qubit platform is generally experimentally challenging. On the other hand, continuous-variable (CV) cluster states have recently been realized among over a million bosonic modes. In our work, we present a hybrid CV-qubit approach to generate entanglement between many qubits by downloading it from...
Studying emergent phenomena in classical statistical physics remains one of the most computationally difficult problems. With the appropriate algorithm to renormalize the system, one of the most effective methods to study these problems is tensor networks. In the context of research areas like condensed matter, the result is a coarse grained and truncated system where only the most relevant...
