If you wanna do some simulations of processes where you're heralding non-gaussian states from gaussian states + photon detectors but you want to include realistic errors like loss and distinguishability, you should check out our paper!
* Simulating lossy and partially distinguishable quantum optical circuits: theory, algorithms and applications to experiment validation and state preparation arxiv.org/abs/2412.17742 in collaboration with @BosonBulmer and co-led by our own Javier Martínez-Cifuentes @polymtl

"No condono la astrología. Divulgarla en los medios de comunicación debería ser tan escandaloso como repartir cigarrillos en los colegios".
Una lectura para cerrar la primera semana del 2025.
Para Navidad y Año Nuevo @elespectador nos propuso el complejo ejercicio de hablar positivamente sobre personas que estén en una orilla ideológica distinta.
El resultado es "Mi amigo, el astrólogo" hoy @EEopinion

Driving is a privilege, not a right. It should be harder to get/keep your license, and if you have multiple DUIs and/or at-fault accidents, you should lose your license permanently - no matter what age you are.

Great pic of Daniela in this latest shot at explaining what we mean by negative time (unfortunately, we're a bit delayed getting our own explainer up there)...

Check out our latest paper on a topic at the intersection of quantum optics and non-Hermitian physics. It is co-first-authored by Polina Blinova, an undergraduate student from Cornell who worked in my research group for two summers, and Evgeny Moiseev, a postdoc in my group.

Supercontinuum's highly sensitive to input's parameters. Machine learning trained on Wigner distros of the input can achieve convergence speedups. Results: 12 fs pulses, full control of dispersive wave, and high-order solutions. 💪Check out aXiv arxiv.org/abs/2411.14410 @femtoQ

The panel discussion on the “future of quantum computing” at #qtml2024 features @quantum_aram, @andrewmchilds, Scott Aaronson, and Ed Farhi delivers a number of highly insightful points. To date, it is not so clear what #quantumcomputing can deliver for the the unstructured problems in common in #machinelearning.

I had a few interactions with John at @ufphysics, and he always lent an ear, even to untrained undergrads. There was not a hint of the usual academic hierarchy in him. I wish I could share with him the things we are working on now. phys.ufl.edu/wp/index.php/20…

An experiment has identified a delay between the detection times of entangled photons that depends on the intensity of the light hitting the crystal, with implications for quantum technologies.

Dear Scientists & Mathematicians, Please use chalk and a duster when teaching. Give up teaching #STEM via PowerPoint/slides. A lot of you, particularly in the engineering sciences, teach entire courses using only slides.
BTW, can you identify these geniuses from their photos?

"We are cutting your funding."
Mathematicians: Whatever, I don't need much research funding
"We are taking away your office."
Mathematicians: Yeah, I can work from home
"We are replacing the blackboards with whiteboards."
Mathematicians: I'll have your job for this!!!
