016 Bloch Sphere Sandbox
SimulatorFree play: set any one-qubit state with sliders or gates and see what you would get if you looked.
Simulator running in your browser. Real hardware: coming soon (planned provider: IBM Quantum).
What's happening?
A free play Bloch sphere simulator: set any single qubit state with Tilt and Turn sliders or apply gates, look at it, repeat 100 times, and share the state as a link. Simulator only.
You will learn: The Bloch sphere: every one-qubit state, its odds, its hidden phase and how gates move it.
How the sphere maps a qubit
Every state of one qubit is a point on a sphere. The top is Heads (0) and the bottom is Tails (1). A point on the equator is a 50/50 mix. The Tilt is the angle down from the top, and the Turn is the angle around the vertical axis. The Heads chance is the square of the cosine of half the Tilt. The Turn is the relative phase between Heads and Tails.
What the buttons do
- Spin the coin (Hadamard) swings the top to the equator and back.
- Flip it over (X gate) swaps Heads and Tails.
- Shift the spin (Z gate), Quarter shift (S gate) and Eighth shift (T gate) turn the arrow around the vertical axis by 180, 90 and 45 degrees. They change the Turn only.
- Flip+ (Y gate) flips and shifts at once.
- Look at the coin collapses the state to Heads or Tails.
- Spin, then try it 100 times shows why the Turn matters: the same odds, different hidden sign, different result after a spin.
Honest notes
- One qubit only. Two or more linked qubits can be in states that no single sphere shows, see entanglement.
- It is a simulator. See The Bloch Sphere Explained for the full explanation.
Run on real hardware: coming soon. The planned provider is IBM Quantum. It is not connected yet. Every result on this page comes from a simulator running in your browser, not from a quantum computer.
How it works: the simulator keeps the exact quantum state of the qubits as a list of complex numbers, applies each gate to it, and draws random samples from the resulting probabilities. The random numbers are ordinary pseudo random numbers from your browser, and a real device would add noise. No QNT, wallet or account is needed.
