New protocol identifies fascinating quantum states

[FfFfFfFF 58,120]

Nowadays, modern quantum simulators offer a wide range of possibilities to prepare and investigate complex quantum states.

They are realized with ultracold atoms in optical lattices, Rydberg atoms, trapped ions or superconducting quantum bits. A particularly fascinating class of quantum states are topological states of matter. 

“Identifying and characterizing such topological phases in experiments is a great challenge,” say Benoît Vermersch, Jinlong Yu and Andreas Elben from the Center for Quantum Physics at the University of Innsbruck and the Institute for Quantum Optics and Quantum Information of the Austrian Academy of Sciences. “Topological phases cannot be identified by local measurements because of their special properties. We are therefore developing new measurement protocols that will enable experimental physicists to characterize these states in the laboratory”.

“The idea of our method is to first prepare such a topological state in a quantum simulator. Now so-called random measurements are performed, and topological invariants are extracted from statistical correlations of these random measurements,” explains Andreas Elben.

i don't understand. what quantum states did they discover? this is too complicated for me

Does anyone else think Chromatica's delay is a good thing? I love quantum mechanics. I think it's a very interesting subject.

 

(But seriously, it's right up my alley. Quantum computing is so cool. It has the potential to turn everything on its head. It's unlikely the average people will have their own quantum computers because these things need to run at ultracold temperatures.)

I wonder what are the implications for such new finding 

In chemistry,  Quantum Mechanics is often applied in spectroscopy - a characterization method of unknown molecules. Or at least that's the only encounter I had with QM (aside from studying it on college).
