Our latest paper was finally published in Nature! --> https://www.nature.com/articles/s41586-026-10356-3
We jumped on the #QuantumComputing bandwagon and demonstrated that we can do 2-qubit gates with very high fidelity in a system with cold fermionic atoms!
The special emphasis lies on the fermionic part - this could enable easier quantum simulation of other fermionic systems, like strongly correlated electrons! (That's basically everything interesting we would want to simulate)

High-fidelity collisional quantum gates with fermionic atoms - Nature

A robust composite pair-exchange gate based on controlled interactions of fermionic atoms in an optical superlattice demonstrates high fidelities and long Bell-state lifetimes, marking an important step towards a fully digital fermionic quantum computer.

@ditsch42 I could follow until "published in Nature" :)

and hey, this is already great. congrats!

@foobarblubb The not-so-fancy description: We can push around single atoms, like the 1's and 0's of a classical computer, and we can do the most simple "calculation" with two such quantum bits in a way that is even correct in 99.75% of the cases!
And because these atoms behave the same as electrons in any material we don't understand yet, this could help us understand more (in the future, with more work and more tools we still need to develop).
@ditsch42 thanks!
I kind of understand the idea of quantum computing, but I cannot fathom the implications of entanglement and superposition. WAY over my head :D
