How to Use This Calculator
  1. Start by filling in the input fields below. Results update instantly as you type, so you can experiment with different values to see how they affect the outcome.
  2. |00⟩ Amplitude — Amplitude of the |00⟩ component Accepts values from -1 to 1 (default: 0.707).
  3. |11⟩ Amplitude — Amplitude of the |11⟩ component Accepts values from -1 to 1 (default: 0.707).
  4. |01⟩ Amplitude — Amplitude of the |01⟩ component Accepts values from -1 to 1 (default: 0).
  5. |10⟩ Amplitude — Amplitude of the |10⟩ component Accepts values from -1 to 1 (default: 0).
