Measuring Entanglement in Qubit System
Vignesh S, Tabish Qureshi
An operational way of measuring entanglement in a balanced two-path interferometers is presented, where path information is carried by some internal degree of freedom which, in tur…
Bohr's complementarity
Diego S. Starke, Jonas Maziero, Marcos L. W. Basso +1
Quantum complementarity is a fundamental feature of quantum systems and has captivated the physics research community for nearly a century, with significant advancements emerging i…
Complementarity Beyond Definite Causal Order
Mohd Asad Siddiqui, Md Qutubuddin, Tabish Qureshi
Wave--particle duality is a cornerstone of quantum mechanics, traditionally formulated under definite causal order. We investigate how complementarity is modified when the temporal…
Unifying Quantum and Classical Dynamics
Abdul Rahaman Shaikh, Tabish Qureshi
Classical and quantum physics represent two distinct theories; however, quantum physics is regarded as the more fundamental of the two. It is posited that classical mechanics shoul…
A Generalized Formulation of Two-Particle Interference
Kamran Nazir, Tabish Qureshi
Two-photon interference is an interesting quantum phenomenon that is usually captured in two distinct types of experiments, namely the Hanbury-Brown-Twiss (HBT) experiment and the…
