Vor 6 Tagen · The uncertainty principle, also known as Heisenberg's indeterminacy principle, is a fundamental concept in quantum mechanics. It states that there is a limit to the precision with which certain pairs of physical properties, such as position and momentum, can be simultaneously known.
Vor 6 Tagen · Non-Hermitian quantum metrology, an emerging field at the intersection of quantum estimation and non-Hermitian physics, holds promise for revolutionizing precision measurement. Here, we present a comprehensive investigation of non-Hermitian quantum parameter estimation in the quantum regime, with a special focus on achieving Heisenberg scaling.
Vor 6 Tagen · Das Heisenberg-Modell in der quantenmechanischen Formulierung ist ein in der theoretischen Physik viel benutztes mathematisches Modell zur Beschreibung von Ferromagnetismus (sowie Antiferromagnetismus und Ferrimagnetismus) in Festkörpern. 1928 haben Werner Heisenberg [1] und Paul Dirac [2] erkannt, dass Ferromagnetismus in einem ...
26. Apr. 2024 · We address the two-qubit quantum teleportation based on the Heisenberg XYZ chain with a magnetic-field gradient affected by intrinsic decoherence. An atomic spin chain is primarily coupled to...
26. Apr. 2024 · By using the concepts of fidelity and average fidelity in the presence of the magnetic field gradient and under the effect of intrinsic decoherence in the current model, and considering the...
Vor 3 Tagen · Werner Karl Heisenberg (pronounced [ˈvɛʁnɐ kaʁl ˈhaɪzn̩bɛʁk] ⓘ; 5 December 1901 – 1 February 1976) was a German theoretical physicist, one of the main pioneers of the theory of quantum mechanics, and a principal scientist in the Nazi nuclear weapons program during World War II.
Vor 4 Tagen · These early attempts to understand microscopic phenomena, now known as the "old quantum theory", led to the full development of quantum mechanics in the mid-1920s by Niels Bohr, Erwin Schrödinger, Werner Heisenberg, Max Born, Paul Dirac and others.
