The fAQ on entanglement - ep. 03
Description
What is quantum entanglement, why do physicists care so much about it, and how is it used in real-world applications like quantum computing and quantum communication?
In this episode, Tai-Danae and Adam discuss these questions and more with physicist Adam Lewis, Technical Lead on SandboxAQ’s Simulation and Optimization team.
