Time-Dependent Hamiltonian Reconstruction using Continuous Weak Measurements
Karthik Siva, Gerwin Koolstra, John Steinmetz +9
Reconstructing the Hamiltonian of a quantum system is an essential task for characterizing and certifying quantum processors and simulators. Existing techniques either rely on proj…
Delayed choice of paths selected by grin and snarl of quantum Cheshire Cat
Debmalya Das, Ujjwal Sen
The so-called quantum Cheshire Cat is a scenario where a photon, identified with a cat, and a component of its polarization, identified with the grin of that cat, are separated. We…
Can Two Quantum Cheshire Cats Exchange Grins?
Debmalya Das, Arun Kumar Pati
A common-sense perception of a physical system is that it is inseparable from its physical properties. The notion of Quantum Cheshire Cat challenges this, as far as quantum systems…
Teleporting Grin of a Quantum Chesire Cat without cat
Debmalya Das, Arun Kumar Pati
Quantum Chesire Cat is a counterintuitive phenomenon that provides a new window into the nature of the quantum systems in relation to multiple degrees of freedom associated with a…
How efficient is transport of quantum cargo through multiple highways?
Saptarshi Roy, Tamoghna Das, Debmalya Das +2
Quantum states can be efficiently transferred over a long distance if the entire quantum channel can be divided into several small blocks. We consider a scenario in which each bloc…
Quantum heat engine based on level degeneracy
George Thomas, Debmalya Das, Sibasish Ghosh
We study a quantum Stirling cycle which extracts work using quantized energy levels of a potential well. The work and the efficiency of the engine depend on the length of the poten…
