Non-Kolmogorov-Arnold-Moser Quantum Sensors for Quantum Parameter Estimation
Naga Dileep Varikuti, Sourav Manna, Athreya Shankar +2
Non-KAM (Kolmogorov-Arnold-Moser) systems, when subjected to weak time-dependent perturbations, exhibit an abrupt transition to classical chaos through the breakdown of invariant p…
Quantum Chaos and Quantum Information: Interactions and Implications
Arul Lakshminarayan, Karol Życzkowski
The notion of Shannon entropy is crucial for the theory of classical information. In quantum information theory, an analogous key role is played by the von Neumann entropy: quantum…
Localizable Entanglement as an Order Parameter for Measurement-Induced Phase Transitions
Sourav Manna, Arul Lakshminarayan, Vaibhav Madhok
We identify localizable entanglement (LE) as an order parameter for measurement-induced phase transitions (MIPT). LE exhibits universal finite-size scaling with critical exponents…
Absolutely maximally entangled pure states of multipartite quantum systems
Grzegorz Rajchel-Mieldzioć, Rafał Bistroń, Albert Rico +2
Absolutely maximally entangled (AME) pure states of a system composed of parties are distinguished by the property that for any splitting at least one partial trace is maximall…
Disordering a permutation symmetric system: revivals, thermalization and chaos
Manju C, Uma Divakaran, Arul Lakshminarayan
This study explores the effects of introducing a symmetry breaking disorder on the dynamics of a system invariant under particle permutation. The disorder forces quantum states, co…
Local unitary equivalence of absolutely maximally entangled states constructed from orthogonal arrays
N Ramadas, Arul Lakshminarayan
The classification of multipartite entanglement is essential as it serves as a resource for various quantum information processing tasks. This study concerns a particular class of…
