Today I review this paper: In this episode, we discuss a new approach to detecting quantum entanglement in many-body systems. The approach is based on Zeeman-sublevel population measurements, and it is more sensitive to entanglement than traditional methods. We explore how this approach can be used to study entanglement in spin-1 and spin-2 Bose-Ei…

Dimiter Ostrev proposes a new QKD protocol that uses two-universal hashing instead of random sampling to estimate the number of bit flip and phase flip errors. This protocol dramatically outperforms previous QKD protocols for small block sizes. Check out the original paper, or read my medium or WordPress versions of the summary.…

The F3 method is a promising new method for optimizing the measurements of electronic Hamiltonians in the VQE. It has the potential to make the VQE more accurate and efficient, and it could make it possible to study molecules that are too large to be studied with the standard VQE method. Read the summary of this paper one of these places!https://me…

I'm not going to abandon WordPress or the podcasts. They all have their places. I believe they all fill different niches. Please check out my work there if you would like, it's another way to support the work I'm doing.Quantum is a hard place to be if you can't read well, and I hope to ease that. The podcast is part of that. I imagine that many of …

Really an interesting subject, I may go back and try to figure out how this works later. This does seem to be something my research could use, but a little far out of what I can manage at the moment. This episode is also available as a blog post: https://quantumsumm.wordpress.com/2023/04/18/learning-temporal-data-with-variational-quantum-recurrent-…
