Generation of large Fock states from coherent states using Kerr interaction and displacement
Nilakantha Meher, Anirban Pathak, S. Sivakumar
We discuss a scheme to generate large Fock states. The scheme involves repeatedly applying an experimentally feasible unitary transformation to convert a semiclassical state into a…
Towards Nonlinear Quantum Thermodynamics
Gershon Kurizki, Nilakantha Meher, Avijit Misra +2
We have recently put forth several schemes of unconventional, nonlinearly-enabled thermodynamic (TD) devices that can operate in either the classical or the quantum domain by trans…
Nonlinearity and Quantumness in Thermodynamics: From Principles to Technologies
Gershon Kurizki, Nilakantha Meher, Tomáš Opatrný
The impact of quantum mechanics on thermodynamics, particularly on the principles and designs of heat machines (HM), has been limited by the incompatibility of quantum coherent evo…
Thermodynamic sensing of quantum nonlinear noise correlations
Nilakantha Meher, Tomáš Opatrný, Gershon Kurizki
We put forth the concept of quantum noise sensing in nonlinear two-mode interferometers coupled to mechanical oscillators. These autonomous machines are capable of sensing quantum…
Supersensitive phase estimation by thermal light in a Kerr-nonlinear interferometric setup
Nilakantha Meher, Eilon Poem, Tomáš Opatrný +2
Estimation of the phase delay between interferometer arms is the core of transmission phase microscopy. Such phase estimation may exhibit an error below the standard quantum (shot-…
