Topological properties and Majorana Multiplicity in Zigzag Kitaev Chain
Rajiv Kumar, Panch Ram, Levan Chotorlishvili +1
We investigate the spectral and topological properties of a zigzag Kitaev chain constructed from two diagonally coupled one dimensional Kitaev chains with a zero and finite superco…
Evaluating quantum circuits in the reservoir computing paradigm
Gaurav Rudra Malik, Amit Kumar Jaiswal, S. Aravinda +1
Reservoir computing is a framework which is primarily used for temporal information processing, using the intrinsic dynamics of an underlying physical system. The framework, in a q…
Clifford and Haar scramblers yield equal mean fidelity but unequal fluctuations in black hole-inspired teleportation
Sudhanva Joshi, Sunil Kumar Mishra
Quantum information transfer between entangled black holes has inspired many-body teleportation protocols. We study such a protocol without assuming a gravitational dual and ask wh…
Majorana bound states in a hybrid Kitaev ladder with long-range pairing
Rajiv Kumar, Tapan Mishra, Levan Chotorlishvili +1
We investigate an inter-leg coupled hybrid Kitaev ladder composed of two parallel superconducting chains with distinct pairing interactions. The upper chain of the ladder hosts con…
Quantum memory and scrambling from the perspective of a classical neural network
Dimitrios Maroulakos, Andrzej Wal, Marcin Kowalik +4
Entropic uncertainty relations are universal quantifiers of fundamental uncertainties of quantum measurements and are widely discussed in the quantum metrology literature. Quantum…
Black-Hole Microstate Hair Requires a Horizon Measurement
Sudhanva Joshi, Sunil Kumar Mishra
Can a smooth horizon hide its microstates? At fixed classical and superselected data, the exterior distinguishability of same-sector infalling states and the departure $…

Sudhanva Joshi, Sunil Kumar Mishra
Holography-inspired teleportation has recently emerged as a significant area of research in quantum many-body systems. In this work, we investigate the effects of sy…
Collective dynamics versus entanglement in quantum battery performance
Rohit Kumar Shukla, Sunil K. Mishra, Ujjwal Sen
We investigate charging dynamics in many-body quantum batteries by examining the relationship between instantaneous charging power and the emergence of bipartite, tripartite, and m…
Krylov complexity in ergodically constrained nonintegrable transverse-field Ising model
Gaurav Rudra Malik, Jeet Sharma, Rohit Kumar Shukla +2
The nonintegrable transverse-field Ising model is a common platform for studying ergodic quantum dynamics. In this work, we introduce a simple variant of the model in which this er…
Dynamics of Majorana zero modes across hybrid Kitaev chain
