Coherence width
WebThe third semantic, size, changes the width of the lines: sns.relplot( data=dots, kind="line", x="time", y="firing_rate", size="coherence", style="choice", ) While the size variable will typically be numeric, it’s also possible to map a categorical variable … WebApr 11, 2024 · Abstract. The statistics of work done on a quantum system can be quantified by the two-point measurement scheme. We show how the Shannon entropy of the work distribution admits a general upper bound depending on the initial diagonal entropy, and a purely quantum term associated to the relative entropy of coherence.

WebBut frequency stability is the same thing as coherence time which in turn gives rise to coherence length. Suppose, for example, that the clock drifts by one second in one hour. This means that its relative frequency stability is approx $3 \times 10^{-4}$ and if its frequency is $12$ GHz then its linewidth will be $3$ MHz and coherence length 90 ...

In physics, coherence length is the propagation distance over which a coherent wave (e.g. an electromagnetic wave) maintains a specified degree of coherence. Wave interference is strong when the paths taken by all of the interfering waves differ by less than the coherence length.
