Vor 3 Tagen · As long as there exists a definite phase relation between different states, the system is said to be coherent. A definite phase relationship is necessary to perform quantum computing on quantum information encoded in quantum states. Coherence is preserved under the laws of quantum physics.
Vor 3 Tagen · Because light at all frequencies travels the same velocity, longitudinal and temporal coherence are linked; in matter waves these are independent. For example, for atoms, velocity (energy) selection controls longitudinal coherence and pulsing or chopping controls temporal coherence.
Vor 2 Tagen · Quantum coherence constitutes a foundational characteristic of quantum mechanics and is integral to emerging quantum resource theories. However, quantum coherence is severely restricted by environmental noise in general quantum processing, indicated by the loss of information of a quantum system. Such processing can be described by the trade-offs between the coherence and the mixedness. Based ...
Vor 5 Tagen · Coherence and Pluralism in the EU’s Open, Green, Digital & Geopolitical Agenda. 20.05.2024 BSOG Policy Forum Series 2024 co-organized by Paula Hoffmeyer-Zlotnik (CCCP) Together with the VUB Brussels School of Governance and partner inst ...
Vor 4 Tagen · A coherence approach based on the wave nature of a photon is adopted to analyze Fig. 1 differently from the quantum approach based on quantum operators 1,26,27,28,29,30,31,32,33. The novel feature ...
Vor 3 Tagen · In this work, we show that the quantum coherence of plasmonic resonances can be enhanced by integrating a plasmonic antenna in a photonic cavity operated at a chiral exceptional point (CEP),...
Vor 5 Tagen · Background Optical coherence tomography (OCT) guidance in percutaneous coronary intervention (PCI) has been shown to improve procedural outcomes. However, evidence supporting its superiority over angiography-guided PCI in terms of clinical outcomes is still emerging and limited. This study aimed to compare the efficacy and safety of OCT-guided PCI versus angiography‐guided PCI in patients ...
