Probing quantum entanglement from magnetic-sublevels populations: beyond spin squeezing inequalities

Quantum Computing Summaries

30:21

Hitting plateaus is a common milestone in business, but there’s a difference between stability and a rut. In the last installment of this season, we’ll dive into the ways small business owners push beyond plateaus and find new ways to achieve revenue growth. Jannese and Austin wrap up their time in Nashville, Tennessee with a wonderful visit to N.B. Goods to speak with owner Camille Alston . Camille details the times where she hit a wall with profits, the strategies she implemented to increase revenue, what worked, what didn’t, and the important lessons she learned in the process. You won’t want to miss this informative final chapter! Learn more about how QuickBooks can help you grow your business: QuickBooks.com See omnystudio.com/listener for privacy information.…

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-Einstein condensates, and we discuss the implications of the results for the development of new quantum technologies.

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.…

Although it is very dense (as most quantum papers are) the four pages it takes up are in no way a waste of time. It may even take less time than this podcast, but you can't drive while doing that. https://quantum-journal.org/papers/q-2023-01-03-890/…

Fluid fermionic fragments for optimizing quantum measurements of electronic Hamiltonians in the variational quantum eigensolver 7:02

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.

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 my listeners are using the podcast to multitask and I love it. And yes, Medium does produce an audio version, but still I think it's key to have a proper podcast. As I am able to commit more time to this, the podcast listeners will be the first to benefit. What do you do while listening?…
