Instructions

1. Build Circuit

Drag and drop gates onto the circuit diagram or use the tab key to navigate to a gate and hit enter to select a position.

2. Select Execution Mode

Get State: View the state vector's complex probability amplitudes.
Sample: Simulate 1000 noise-free shots.
Run: Shot-based execution with specified measurements.

3. Generate Code and View Emulated Results

Example Circuits Guide

Bell State (|Φ⁺⟩)

2 Qubits: The simplest example of entanglement. Measures 00 or 11 with 50/50 probability.

GHZ State

3 Qubits: Maximally entangled state for 3 qubits. Results are 000 or 111.

Bernstein-Vazirani

3 Qubits: Finds a secret bitstring (101) hidden in an Oracle function in a single step.

Quantum Teleportation

3 Qubits: Teleports state from q0 to q2.
We prepare q0 in the state, |-i>. When teleported, we verify it by measuring q2 in the my basis. In "Run" mode, q2 should be True 100% of the time.
