Decoherence Suppression in Phase Decoherence Environment Using Weak Measurement and Quantum Measurement Reversal

Abstract: Decoherence suppression from disturbance of the environment is an essential task in quantum information processing. We investigate decoherence suppression of a qubit system interacting with a heat bath with phase decoherence by employing the weak measurement (WM) and quantum measurement reversal (QMR) operation. We show explicitly that the qubit decoherence can be efficiently completely suppressed by means of the combination WM and QMR, which is independent of the form of the spectral density of the reservoir and the form of initial input state.

(2,2′‐Bipyridine‐κ2N,N′)(4′‐ferrocenyl‐2,2′:6′,2′′‐terpyridine‐κ3N,N′,N′′)copper(II) bis(tetrafluoridoborate)

Abstract: In the title complex, [CuFe(C5H5)(C20H14N3)(C10H8N2)](BF4)2, the CuII atom is five-coordinated by a tridentate chelating 4′-ferrocenyl-2,2′:6′,2"-terpyridine (fctpy) ligand and a bidentate chelating 2,2′-bipyridine (bpy) ligand. The coordination polyhedron is distorted square-pyramidal with an N atom from the bipyridine ligand in the apical position at a Cu—N distance of 2.195 (3) A. In the crystal structure, tetra­fluoridoborate counter-ions are involved as acceptors in inter­molecular C—H⋯F hydrogen-bonding inter­actions with both the bipyridyl and terpyridyl ligands, resulting in a three-dimensional supra­molecular structure.

Multiplicity of solutions for fractional Schrödinger equations with perturbation

Abstract: In this paper, we investigate a class of fractional Schrodinger equations with perturbation. By using the mountain pass theorem and Ekeland’s variational principle, we see that such equations possess two solutions. Recent results in the literature are generalized and significantly improved.
