Scientists might have reached the theoretical limit of how strong this particular material can get, designing the first-ever super-light carbon nanostructure that’s stronger than diamond.

The latest development in the nanoworld of carbon comes from a team that has designed something called carbon plate-nanolattices. Under a scanning electron microscope, they look like little cubes, and the math indicated that this structure would be incredibly strong, but it’s been too difficult to actually make, until now.

The team’s success was made possible by a 3D printing process called two-photon polymerization direct laser writing, which is essentially 3D printing on the level of atoms and photons.

Seeker examines a leaked paper from Google claimed that a quantum computer demonstrated “quantum supremacy.”

But what does that mean exactly?

Quantum computers’ potential and the advantages they promise over classical computers all remain largely theoretical, and hypothetically speaking, it is predicted that quantum computers will be able to solve problems that are beyond the reach of the classical computers we use today. Passing such a threshold will be considered proof of what we call “quantum supremacy.”
