With quantum computers breaking most if not all of our currently used public-key cryptography, #quantum #cryptography offers a secure alternative. “Secure” as in information-theoretically secure, i.e., unbreakable.
For anybody interested in the current developments in this field, the research group I work at published an interesting article about their current work in the journal #PRX Quantum:

Don't be scared of actually reading the paper “Scalable Networks for Simultaneous Pairwise Quantum Key Distribution via Entanglement-Based Time-Bin Coding”!
