Evolution of the entanglement of the -type of states in a coupled two cavity system via an adiabatic approximation
R. Chakrabarti, G. Sreekumari, V. Yogesh
We study a system of two cavities each encapsulating a qubit and an oscillator degrees of freedom. An ultrastrong interaction strength between the qubit and the oscillator is assum…
Simulating Dirac Hamiltonian in Curved Space-time by Split-step Quantum Walk
Arindam Mallick, Sanjoy Mandal, Anirban Karan +1
Dirac particle represents a fundamental constituent of our nature. Simulation of Dirac particle dynamics by a controllable quantum system using quantum walks will allow us to inves…
The role of short periodic orbits in quantum maps with continuous openings
Carlos A. Prado, Gabriel G. Carlo, R. M. Benito +1
We apply a recently developed semiclassical theory of short periodic orbits to the continuously open quantum tribaker map. In this paradigmatic system the trajectories are partiall…
Quantum speed limit constraints on a nanoscale autonomous refrigerator
Chiranjib Mukhopadhyay, Avijit Misra, Samyadeb Bhattacharya +1
Quantum speed limit, furnishing a lower bound on the required time for the evolution of a quantum system through the state space, imposes an ultimate natural limitation to the dyna…
Generalized formalism for information backflow in assessing Markovianity and its equivalence to divisibility
Sagnik Chakraborty
We present a general framework for the information backflow (IB) approach of Markovianity that not only includes a large number, if not all, of IB prescriptions proposed so far but…
Quantum Query Algorithms are Completely Bounded Forms
Srinivasan Arunachalam, Jop Briët, Carlos Palazuelos
We prove a characterization of -query quantum algorithms in terms of the unit ball of a space of degree- polynomials. Based on this, we obtain a refined notion of approximat…
