Quantum Phase Shifter — Gate Calibration on the Bloch Sphere

Prepare a qubit in |+⟩ and dial a continuous phase-shift angle φ: watch it rotate live around the Bloch-sphere equator through the Identity, T, S and Z gate angles, then hit an exact target angle and read the live fidelity of the resulting quantum gate.

A programmable phase shifter applies an adjustable phase shift φ to one branch of a qubit's superposition. Starting from |+⟩, sweeping φ traces the state around the Bloch sphere's equator, passing through the exact angles that implement the Identity, T, S and Z gates. Pick a target gate and dial in its exact angle to see how calibration precision determines which gate actually gets applied.

⚙ Under the hood

Prepare a qubit in |+> and dial a continuous phase-shift angle phi with a live-updating Bloch-sphere arrow: sweep through the exact Identity, T, S and Z gate angles, pick a target gate, and read a live fidelity score showing how precisely the phase shifter is calibrated to implement it.
