Create a Bell State

  1. Place an H gate on qubit 0 to create superposition.
  2. Add a CNOT with control on qubit 0 and target on qubit 1.
  3. Run the circuit in the simulator or on AWS Braket via Qly.

You should observe correlated outcomes 00 and 11 with ~50% probability each.

Playground overview with gates and empty circuit
1) Open the Playground. Set qubits/time steps, then drag an H gate to Q0 at t0.
CNOT placement: control on Q0 and target on Q1 in the same column
2) Add CNOT: drag the control (●) to a column, then click an empty cell in that column to place the target (⊕).

3) Run the job. On the Jobs page, verify OpenQASM shows cx and measurement results peak around 00 and 11.
