Futurology

The researcher's breakthrough is in finding a way that entangled quanta of light can use today's fiber-optic cable technology to transmit at long distances. This is important because it means the future quantum internet can be built quickly and inexpensively from common mass-produced materials.

There's a hitch - no one's succeeded in building large scale working quantum computers yet. How soon will they arrive? Who knows. The field is advancing rapidly, but some say it could still be many years.

Here's a University of Chicago article about the quantum internet.

Here's Physicist Michio Kaku talking about quantum computers.

Worth noting that it was only two microseconds, which while might open up new possibilities is still limited by losses at every repeater from my understanding.

Also with noting that the quantum internet has to do with quantum key cryptography, and quantum computing isn’t really relevant.
