CHALLENGE #6: THE OTHER BELL STATES 🔔
Last week we explored the foundational Bell state! Did you know there are actually four Bell states, each showing a unique type of entanglement? We can create them using the same H and CNOT gates, with just one small addition.
Task: Your goal is to create a Bell state that outputs only 01 and 10 in the histogram, the exact opposite of last week's 00/11 output.
Easy mode: Add a single X gate after the CNOT. Experiment to find which qubit needs it to achieve the 01/10 outcome.
Stretch: Now, try adding a Z gate instead of an X gate after the CNOT. You'll notice the histogram looks the same as the classic Bell state! Where did the difference go, and why doesn't the histogram show it?
Build it in the Quantum Quest simulator and share your result with the 📸 Community button.
