This monthly series will feature open, interdisciplinary talks by Lithuanian and international researchers working in quantum physics, quantum technologies, and related fields. Topics will range from fundamental questions in quantum science to applied developments in quantum communication, sensing, and computing.

 

The aim of this series is to foster knowledge exchange, dialogue, and collaboration across different research areas, encouraging synthesis and joint initiatives across disciplines.

 

The first seminar will take place on Thursday, May 8th at 14:00 in NFTMC, room D401. The speaker will be Dr Emilia Witkowska from the Institute of Physics, Polish Academy of Sciences The topic she will present is "Spin chains and squeezing: simple theoretical results".

 

"Entanglement in systems with single-particle control is a well-established resource of modern quantum technology. Spin-squeezing is a great example of such. Applied in an optical lattice clock it can reduce the statistical uncertainty of spectroscopic measurements.

 

During the seminar, I will consider the dynamic generation of spin squeezing in spin chains. I will show how anisotropic interactions and inhomogeneous magnetic fields generate scalable spin squeezing when their magnitudes are sufficiently small, but not negligible. The simple models for collective spin will be shown to describe the dynamics effectively. I will also discuss the effect of nonuniform filling caused by holes, at a microscopic level, demonstrating their limiting role in the dynamics and scaling," explains E. Witkowska.

 

We warmly invite you to attend and follow updates about upcoming talks!
