Extending spin-lattice relaxation theory to three-phonon processes
Nilanjana Chanda, Alessandro Lunghi
Spin-lattice relaxation theory has been developed over almost a century, but some cardinal assumptions on the nature of the interactions involved have never been fully verified. Th…
Optimal fidelity in implementing Grover's search algorithm on open quantum system
Nilanjana Chanda, Rangeet Bhattacharyya
We investigate the fidelity of Grover's search algorithm by implementing it on an open quantum system. In particular, we study with what accuracy one can estimate that the algorith…
Optimal population transfer using the adiabatic rapid passage in the presence of drive-induced dissipation
Nilanjana Chanda, Pratik Patnaik, Rangeet Bhattacharyya
Adiabatic rapid passage (ARP) is extensively used to achieve efficient transfer or inversion of populations in quantum systems. Landau and Zener accurately estimated the transfer p…
Emergence of the Born rule in strongly-driven dissipative systems
Nilanjana Chanda, Rangeet Bhattacharyya
To understand the dynamical origin of the measurement in quantum mechanics, several models have been put forward which have a quantum system coupled to an apparatus. The system and…
Optimal Clock Speed of Single-Qubit Operations on Open Quantum Systems
Nilanjana Chanda, Rangeet Bhattacharyya
Efficient implementation of quantum algorithms requires single- or multi-qubit gates with high fidelity. In this report, we report that the fidelity of single-qubit gate operations…
