It's a Thing, Actually
Quantum superposition is a real phenomenon where a quantum system can exist in multiple states simultaneously.
Think of it like you're at a restaurant with a menu that has multiple items you want to order.
Just as you can point to the menu and say "I'll have the burger, the fries, and the ice cream" – even though you can only eat one thing at a time – a quantum system can exist in multiple states at once.
It's not just a figure of speech, it's a fundamental aspect of quantum mechanics.
But don't just take our word for it. Read the research papers.
