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. Want to get in touch?
