Nicolas (github.com/NDalbec) presented the results of his mémoire de maîtrise, on Accurate unsupervised photon counting from transition edge sensor signals!
The results he obtained are reported on this preprint arxiv.org/abs/2411.05737 .

For the engineering physics seminar @polymtl today, @CRios_O from @UofMaryland is telling us about how phase-change materials are great for photonics, especially for slow applications.

Very timely reading from Tom Chivers' Everything is predictable: "research is more complex now, and we have the technology to present it all and the moving parts". So, do come to the @NeuroLibre workshop this friday organized by @Stikov this Friday in Montréal!

I've decided to interpret this fuzzy ball as a good omen for the grants to be submitted this week.

If you want to hear more about this, you should check @GThekkadath talk @PhotonicsNorth on May 28th

The theory developed by them in collaboration with M. Houde (from our group at @polymtl) nicely matches their experiments. See the figure below for a comparison:

@GThekkadath and our friends at NRC came up with a very clever way of measuring this delay using intensity interferometry and (surprisingly!) click detectors (notice that this effect happens in the high-gain).

These corrections modify the JSA of squeezed light as the gain is increased, in particular they endow the JSA with a nontrivial phase structure which changes the group delay of signal and idler photons:

Genial ver la investigación del profesor de la @udea Marco Giraldo (scholar.google.com/citations…) sobre los colores de las alas de las mariposas en el último vídeo de Ze Frank: piped.video/watch?v=v-s714RN…

well, we woke up to this. I guess we need some consultants to get proper bollards @WorldBollard . More seriously, even here car culture is awful and road and street engineering is shit. As @NotJustBikesToo would say, Montreal is three nice neighbourhoods on a trench coat.

And finally just a point of clarification: you can do discrete variables in strawberry fields contrary to what is claimed here. A nice example of DC is this one strawberryfields.ai/photonic… .

It also seems like you all are die hard swifties, since you only like the Taylor version of the exponential.

Congrats on the publication of this work @MarioKrenn6240 ! I meant to ask you: What is the complexity of your method? For computing Takagi of an n x n matrix is the same as SVD (so ~ n^3) and for calculating a hafnian of n x n is (n^3 x 2^n).

Apparently now it needs to be clarified that not all Boson Sampling is Gaussian Boson Sampling. Very nice talk by Josh Nunn about @orcacomputing plans.

On Friday Martin Houde will be presenting our work on Waveguided Sources of Consistent, Single-Temporal-Mode Squeezed Light: the Good, the Bad, and the Ugly at @CLEOConf . If you happen to be in San Jose, go and check it out!
