In this episode, Seeker tackles the question that’s on everyone’s minds: what will it take to have quantum internet in our home?

Yes, Virginia, a quantum internet is in the works.

The U.S. Department of Energy recently rolled out a blueprint describing research goals and engineering barriers on the way to quantum internet.

The DOE’s latest blueprint for a quantum internet in the U.S. has four key milestones. The first is to make sure quantum information sent over current fiber optic cables is secure. Then to establish entangled networks across colleges or cities, then throughout states, and finally for the whole country.

In this video, Sabine Hossenfelder explains how public key cryptography works on the internet today, using RSA as example, what the risk is that quantum computers pose for internet security, what post-quantum cryptography is, how quantum key distribution works, and what quantum cryptography is.

Wall Street Journal explores the future of satellite internet.

The most reliable streaming providers have typically used cable to deliver content. But that’s all changing with the launch of new and better satellites that could one day give us 5G, low latency data. The Wall Street Journal speaks with the chief of the International Bureau at the FCC to discover how those changes are happening almost overnight.
