I have a new paper, “Information complementarity in quantum physics” on the ArXiv preprint server. We studied the distribution of information in a whole zoo of pure and mixed two-photon quantum states and demonstrate experimentally that local information is complementary to information stored in correlations. The paper contains the probably most extensive range of experimentally […]

Our paper Discrete, tunable color entanglement has been published in Physical Review Letters. Two photons can be entangled in many different degrees of freedom, such as their polarization (the all-time favorite in the community). Photon pairs created in spontaneous parametric downconversion are intrinsically entangled in energy (and thus in frequency) and momentum. The frequency entanglement […]

Sometimes, when chasing up a reference, I come across a journal websites which I haven’t used before. Once I find the desired article, I usually read the abstract and then proceed to downloading the paper in PDF format. One would think that this is the most common procedure for visitors to a journal website. Alas, […]

The Nature Publishing Group (NPG) has just announced a new journal – Nature Communications. This is apparently an attempt at providing a home for excellent research which is not broad enough to be interesting for the general readership of  Nature and at the same time not necessarily covered in a dedicated Nature research journal like […]

Our paper “Anti-symmetrisation reveals hidden entanglement” has been accepted to published in New Journal of Physics. This is one out of four papers which formed my PhD thesis and the last one to make it into a peer-review journal. The paper offers a new take on the famous Hong-Ou-Mandel effect in quantum optics. Imagine two photons […]

My name is Alessandro Fedrizzi, I’m a researcher at the Department of Physics and Centre for Quantum Computer Technology at the University of Queensland, Brisbane, Australia. This ‘blog’ is less a blog than a personal website. I will however — now and then, whenever I feel the urge — blog about things that interest me; […]
