Coherence (signal processing) In signal processing, the coherence is a statistic that can be used to examine the relation between two signals or data sets. It is commonly used to estimate the power transfer between input and output of a linear system. If the signals are ergodic, and the system function is linear, it can be used to estimate the ...
Vor 5 Tagen · While studying quantum optics, the term coherence is often used for the state of light-emitting atoms or ions. In that case, coherence refers to a correlation and phase relationships between the complex amplitudes corresponding to electronic states. This is important, e.g., in the context of lasing without inversion.
Vor einem Tag · Consciousness, at its simplest, is awareness of internal and external existence. [1] However, its nature has led to millennia of analyses, explanations and debate by philosophers, theologians, and scientists. Opinions differ about what exactly needs to be studied or even considered consciousness.
Vor 2 Tagen · Fluxonium qubits are recognized for their high coherence times and high operation fidelities, attributed to their unique design incorporating over 100 Josephson junctions per superconducting loop. However, this complexity poses significant fabrication challenges, particularly in achieving high yield and junction uniformity with traditional methods. Here, we introduce an overlap process for ...
Vor einem Tag · In particular, optical coherence tomography (OCT) can offer valuable insights into vessel and plaque characteristics. When used after PCI, OCT can also give important information on stent implantation, highlighting eventual needs for PCI optimisation and, therefore, contributing to improved PCI outcomes. However, OCT remains underused because of concerns regarding procedural time, costs and ...
