Wave and particle properties can be spatially separated in a quantum entity
Pratyusha Chowdhury, Arun Kumar Pati, Jing-Ling Chen
Wave and particle are two fundamental properties of Nature. The wave-particle duality has indicated that a quantum object may exhibit the behaviours of both wave and particle, depe…
Reverse Quantum Speed Limit: How Slow Quantum Battery can Discharge?
Brij Mohan, Arun Kumar Pati
We introduce the notion of reverse quantum speed limit for arbitrary quantum evolution which answers a fundamental question: ``how slow a quantum system can evolve in time?" Using…
Classical Communications with Indefinite Causal Order for completely depolarizing channels
Sk Sazim, Michal Sedlak, Kratveer Singh +1
If two identical copies of a completely depolarizing channel are put into a superposition of their possible causal orders, they can transmit non-zero classical information. Here, w…
Creation of quantum coherence with general measurement processes
Sanuja D. Mohanty, Gautam Sharma, Sk Sazim +2
Quantum measurement not only can destroy coherence but also can create it. Here, we estimate the maximum amount of coherence, one can create under a complete non-selective measurem…
Estimating quantum coherence by noncommutativity of any observable and its incoherent part
Tanaya Ray, Ahana Ghoshal, Arun Kumar Pati +1
We establish a lower bound on the quantum coherence of an arbitrary quantum state in arbitrary dimension, using a noncommutativity estimator of an arbitrary observable of sub-unit…
Quantum State Interferography
Surya Narayan Sahoo, Sanchari Chakraborti, Arun K. Pati +1
Quantum State Tomography (QST) has been the traditional method for characterization of an unknown state. Recently, many direct measurement methods have been implemented to reconstr…
