Check out our new Science Advances paper, a collaboration with Radek Łapkiewicz's group. We introduces a new phase imagig technique that works when conventional interferometric techniques fail due to noise.

Check out our new Physical Review Letters paper, in which we have deonstrated a new entanglement measurement technique. This method allows to measure entanglement in a specific type of mixed qubit state without detecting one of the particles. The experiment was performed in the lab of Anton Zeilinger (Physics Nobel Laureate 2022). Other collaborators are Gabriela B. Lemos and Radek Lapkiewicz. A theoretical description of the experiment was published before in Physical Review A.

Mayukh, jointly with colleagues, published an article in Reviews of Modern Physics. One of the coauthors is Prof. Anton Zeilinger, who won the 2022 Nobel Prize in Physics. This article highlights new research directions in quantum information science, which are based on a unique concept namely, quantum indistinguishability by path identity. The concept of path idenity was introduced in 1990's, but was then almost forgotten; research in the past few years awakened this sleeping beauty. 

Mayukh, with his colleages, have written a tutorial on quantum imaging and metrology with undetected photons. It is published in the Journal of the Optical Society of America B.

We have shown for the first time that the entanglement in a two-particle mixed state can be verified and measured by detecting only one of the particles. The work is published in Physical Review A. This theoretical work is supported by experimental evidence, which can be found here.
