Quantum Aberrations: Entangling Photons with Zernike Polynomials
Hakob Avetisyan, Gor Nikoghosyan
We introduce Zernike polynomials as a novel degree of freedom for encoding quantum information in the spatial structure of photons. Building on their orthogonality and completeness…
Molecular Nanomagnet as Resource for Bipartite and Tripartite Quantum Entanglement and Coherence
Azadeh Ghannadan, Hamid Arian Zad, Saeed Haddadi +3
We investigate key quantum characteristics of the mixed spin-(1/2,1,1/2) Heisenberg trimer under the influence of an external magnetic field. Specifically, we analyze the distribut…
Energy densities in quantum mechanics
V. Stepanyan, A. E. Allahverdyan
Quantum mechanics does not provide any ready recipe for defining energy density in space, since the energy and coordinate do not commute. To find a well-motivated energy density, w…
Photon cooling: linear vs nonlinear interactions
A. Hovhannisyan, V. Stepanyan, A. E. Allahverdyan
Linear optics imposes a relation that is more general than the second law of thermodynamics: For modes undergoing a linear evolution, the full mean occupation number (i.e. photon n…
Sub-barrier quantum tunneling: eliminating the MacColl-Hartman paradox
Atom Zhora Muradyan
I show that the MacColl-Hartman effect, namely, the saturation of the group delay time of sub-barrier quantum tunneling as a function of the barrier width, comes from the saturatin…
Continuous Variable Quantum Algorithms: an Introduction
Samantha Buck, Robin Coleman, Hayk Sargsyan
Quantum computing is usually associated with discrete quantum states and physical quantities possessing discrete eigenvalue spectrum. However, quantum computing in general is any c…
