#2Seems like we are moving from theory to pactice faster than expected.

#5For real? I wouldn't have thought so many would be possible so soon. Might actually need to look into quantum computing again after 20 years.

It is still orders of magnitude away from breaking RSA 2048 even under the most optimistic assumptions. And qubits double waaay slower than transistors so far.

#7I find the editorialized title misleading. They trapped 17000 atom pairs in an optical lattice and demonstrated a high-fidelity quantum gate between the atoms of each pair in parallel. There is no interaction between the atoms of different pairs and no individual control. The experiment demonstrates a very robust gate scheme, but is a long way from a programmable computer.

They did not make a 17000 qubit computer. The qubits were not controllable or general in any way. The paper is linked, look at it.
This title is misleading.

This is not a 17000 qubit general computer. Read the paper.

#10How does this bring us closer to a 17000 qubit computer and how close are we?
