Here are my reading notes on the quantum optics and photonics preprints in July 2018. This has been a good month for sources of nonclassical light: three groups implemented a source of polarisation-entangled photon pairs using Sagnac interferometer; Vernon et al proposed a CV-squeezed light source based on a χ(3) microresonator; and three standards institutes INRIM (Italy), NPL (UK) and PTB (Germany) reported a concerted effort to standardise g(2) measurements. On the detection side, Goswami, Heshami and Simon proposed a scheme for the non-destructive detection of single-photon time-bin qubits.
Here are my quantum optics and photonics reading notes from June 2018: including a linear interferometer with source and detector on chip and theoretical advances on discriminating distinguishability and on linear bosonic channels.
We have a new manuscript on arXiv titled “Understanding quantum physics through simple experiments: from wave-particle duality to Bell’s theorem”. The manuscript comprises an outline for a course, which was conceived by Christoph Simon at the University of Calgary, about conveying quantum mysteries to students without any prerequisites in mathematics.
Here are the quantum optics gifts that Arxiv brought us in May 2018. I’ve added more papers this month than ever to my to-read-later list. (Sidenote: It would be cool to check if this bump in interesting quant-ph papers is a result of a bump in submitted quant-ph papers that happens every May when teaching recedes. Old arXiv stats seem to show that Cond-matt submissions go up in May but not HEP. Funnily enough, the numbers of downloaded papers show no such bump!) The papers that I did read are:
Following up from the March post, April 2018 in quantum optics was just as exciting: from integrated photonics for random number generation and for continuous variable quantum information, to new witnesses of multi-photon indistinguishability and of entanglement, and the release of an open-source photonics front-end/simulator. Here are my reading notes.
New research on quantum has exploded in the last decade. The number of articles in quantum optics and photonics seems to have gone up hand in hand. These public-facing reading notes are my attempt to tame the flood of new research in the field and to keep myself up to date:
Our paper “Proposal for Quantum Simulation via All-Optically-Generated Tensor Network States” is now published in PRL. (Phys. Rev. Lett. 120, 130501 | arXiv:1710.06103). This paper combines ideas from my two main research interests: quantum optics and tensor networks. Here is an accessible (to a quantum optics audience) summary of the paper:
Hello everyone and welcome to my blog! I am blogging about my research interests, such as quantum optics and tensor networks, hoping to reach out to others with related interests. There might be occasional blurbs about how to solve it in python. I am excited to see where this blog goes!
