Nature research paper: An ultra-broadband photonic-chip-based parametric amplifier https://go.nature.com/41J7Jr6
An ultra-broadband photonic-chip-based parametric amplifier - Nature
An optical parametric amplifier based on integrated photonic circuits fabricated using low-loss gallium phosphide-on-silicon dioxide demonstrates improved bandwidth and gain performance over state-of-the-art erbium-doped fibre amplifiers while maintaining a low noise figure.

Use of michelson interferometer in dark state configuration and reducing photon number variance(radiation pressure variance) by squeezing on photon number quadrature can be a useful in improving sensitivity of the LIGO experiment
Imaging beyond diffraction limit where detector noise can be mitigated by the squeezed vacuum injection is another useful application
Advent of Gaussian Boson Sampling experiments had yielded a significant route for optical CV-quantum computation especially where distribution sampling tomography can yield the desired solutions
optical parametric amplifiers are capable of generating multitude squeezed states of light for use in both vacuum squeezed states as well as bright squeezed states in multimode squeezing applications
Squeezed light is used in both Squeezed Vacuum, as well as Squeezed Bright light each with correspondent uses (compensate for detector noise in former and generating sub-poissonian light in latter)
Squeezed light continues to move beyong single mode applications into multimode spatially squeezed modes which leads to Quantum Imaging. Photon quadrature are squeezed pairs, Photon number and phase are quadrature pairs etc. 1/2
Leonard Mandel, whom ECG Sudharshan recruited to Univ of Rochester, laid foundations of balanced homodyne detection and enabled field measurement of optical fields instead of just intensity by use of this clever interferometric technique
Quantum states of light that are squeezed in any quadrature can have an ability to improve measurement noise along that quadrature beyond the standard quantum limit
Squeezed light has been one of the most deequently accessed modalities of Squeezed states
while theoretically prophesied till the 1970s we have experimental evidence since the 1980s and applications since the 90s.
Starting from Heisenberg microscope to the LIGO advanced detectors there is a big story of squeezed light
If you have worked in Quantum Optics or have knowledge of Squeezed Light or Squeezed quantum states and like to share your story with me please drop me a line muthu@panmo.cloud
writing a book and re-reading my dissertation has been significantly helped by literature search has propelled toward this attempt to write it all down
I've been writing about squeezed light based on some curiosity triggered by my phd work on multimode traveling wave parametric amplifier research; two years ago i planned to write a book on "Measuring Beyond the Quantum Limit : Squeezed Light"
some of the fun and surprising stuff one can learn from Quantum Optics is the following: - spontaneous emission is stimulated emission by zero point vacuum fluctuations - Maxwells equations are true up to the single photon level this story of light is so fascinating

"can em fields exist with phase shift between E and B components?" appare yes
got my vaccine shot for flu; covid-19 was updated earlier in the year too. So vaccine folks is there a thing like fall and spring vaccines ?

#ICYMI: Dark matter researchers have seen something unusual in the LZ detector. Physicist Richard Gaitskell talks with @scifri.bsky.social about the hunt for a #DarkMatter particle and what’s so interesting about the recent result.
Did scientists just find a dark matter particle? Maybe
The LUX-ZEPLIN detector picked up a strange signal that scientists haven't cracked yet. Could it be a dark matter interaction?

This infectious disease doc in training encourages you to get your flu and COVID shots this season! Preferably somewhere you get paid to do so. Thrilled with my $20 credit toward groceries for protecting myself from severe flu and covid infections!
Just got my flu and covid boosters. I'll be sure to take some Tylenol when my arm aches to ensure maximum levels of autism.
