General Machine Learning Algorithm for Quantum Teleportation
Allison Brattley, Tomas Opatrny, Kunal K. Das
We present a general algorithm, based on machine learning, which can create optimal unitary operators to implement quantum teleportation in any system with well-defined set of meas…
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…
Spin Orbit and Hyperfine Simulations with Two-Species Ultracold Atoms in a Ring
Allison Brattley, Tomáš Opatrný, Kunal K. Das
A collective spin model is used to describe two species of mutually interacting ultracold bosonic atoms confined to a toroidal trap. The system is modeled by a Hamiltonian that can…
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-…
Entangled Collective Spin States of Two Species Ultracold atoms in a Ring
Tomáš Opatrný, Kunal K. Das
We study the general quantum Hamiltonian that can be realized with two species of mutually interacting degenerate ultracold atoms in a ring-shaped trap, with the options of rotatio…
Work extraction from single-mode thermal noise by measurements: How important is information?
Avijit Misra, Tomas Opatrný, Gershon Kurizki
Our goal in this article is to elucidate the rapport of work and information in the context of a minimal quantum mechanical setup: A converter of heat input to work output, the inp…
