Quantum coherence with incomplete set of pointers and corresponding wave-particle duality
Ingita Banerjee, Kornikar Sen, Chirag Srivastava +1
Quantum coherence quantifies the amount of superposition in a quantum system, and is the reason and resource behind several phenomena and technologies. It depends on the natural ba…
Quantum information can remain without physical body in volatile form
Brij Mohan, Sohail, Chirag Srivastava +2
A deeply rooted view in classical and quantum information is that "information is physical", i.e., to store and process information, we need a physical body. Here we ask whether qu…
Noisy quantum input loophole in measurement-device-independent entanglement witnesses
Kornikar Sen, Chirag Srivastava, Shiladitya Mal +2
Entanglement witnesses form an effective method to locally detect entanglement in the laboratory without having the prior knowledge of the full density matrix. However, separable s…
Scaling of non-adiabaticity in disordered quench of quantum Rabi model close to phase transition
Chirag Srivastava, Ujjwal Sen
Dynamics of a system exhibits non-adiabaticity even for slow quenches near critical points. We analyze the response to disorder in quenches on a non-adiabaticity quantifier for the…
Equilibrium and dynamical phase transitions in fully connected quantum Ising model: Approximate energy eigenstates and critical time
Arun Sehrawat, Chirag Srivastava, Ujjwal Sen
We study equilibrium as well as dynamical properties of the finite-size fully connected Ising model with a transverse field at the zero temperature. In relation to the equilibrium,…
Resource theory of quantum coherence with probabilistically non-distinguishable pointers and corresponding wave-particle duality
Chirag Srivastava, Sreetama Das, Ujjwal Sen
One of the fundamental features of quantum mechanics is the superposition principle, a manifestation of which is embodied in quantum coherence. Coherence of a quantum state is inva…
