CHALLENGE #1: THE BELL STATE 🔔
The first real one. Classic for a reason.
Task: entangle two qubits so the histogram shows ONLY 00 and 11, roughly 50/50. Nothing else allowed in there.
Easy mode: two gates is all it takes. (The simulator's Challenges tab has this exact one if you want guided checking.)
Stretch: now produce the opposite correlation — only 01 and 10. One extra gate. Which gate, and where? Explain your answer in the comments.
📸 your histogram and post it here. Multiple different-looking solutions absolutely exist.
