A low-loss telecom-band nanofiber cavity for interfacing Yb atomic qubits
We demonstrate the fabrication of an optical nanofiber cavity designed for efficient interface with ytterbium (Yb) atoms at telecom-wavelength transitions. Replacing the conventional hydrogen-oxygen flame with a deuterium-oxygen flame in the heat-and-pull method suppresses hydroxyl-induced absorption losses and enables low-loss nanofiber production with minimal modifications to the existing fabrication system. Using this technique, we fabricate a nanofiber cavity at 1389 nm that exhibits an int…

Sonnet 109 - CIX
O! never say that I was false of heart,
Though absence seem'd my flame to qualify,
As easy might I from my self depart
As from my soul which in thy breast doth lie:
That is my home of love: if I have ranged,
Like him that travels, I return again;
Just to the time, not with the time exchanged,
So that myself bring water for my stain.
Never believe though in my nature reigned,
All frailties that besiege all kinds …

Sonnet 001 - I
From fairest creatures we desire increase,
That thereby beauty's rose might never die,
But as the riper should by time decease,
His tender heir might bear his memory:
But thou contracted to thine own bright eyes,
Feed'st thy light's flame with self-substantial fuel,
Making a famine where abundance lies,
Thy self thy foe, to thy sweet self too cruel:
Thou that art now the world's fresh ornament,
And onl…
