Extending the dynamic range in quantum frequency estimation with sequential weak measurements
Su Direkci, Manuel Endres, Tuvia Gefen
Quantum metrology explores optimal quantum protocols for parameter estimation. In the context of optical atomic clocks, conventional protocols focus on optimal input states and mea…
Interference in Quantum Mechanics
Debadrita Ghosh, Urbasi Sinha
Physicist and Nobel Laureate Richard P. Feynman once remarked ``We choose to examine a phenomenon which is impossible, absolutely impossible, to explain in any classical way, and w…
From Chiral Topological Dynamics to Chiral Topological Amplification: Real vs Imaginary Parameters in a Hermitian Bosonic Chain
Kiran Babasaheb Estake, T. R. Vishnu, Dibyendu Roy
We propose a Hermitian quadratic bosonic model (QBH) whose dynamical matrix exhibits distinct topological and dynamical phenomena depending on whether the hopping and pairing ampli…
Effect of Weak Measurement Reversal on Quantum Correlations in a Correlated Amplitude Damping Channel, with a Neural Network Perspective
Venkat Abhignan, Bidyut Bikash Boruah, R. Srikanth +1
We study the evolution of quantum correlations in Bell, Werner, and maximally entangled mixed states of two qubits subjected to correlated amplitude-damping channels. Our primary f…
Temporal steering of entanglement decay with single-shot control
Saumya Ranjan Behera, Kallol Sen, Animesh Sinha Roy +4
Entanglement in open quantum systems can vanish abruptly through entanglement sudden death (ESD) under dissipative evolution, posing a challenge for quantum technologies. Here, we…
