Wrelks is a toy quantum circuit simulator, forked from Quirk, designed to show how Quantum Gate Matrices are applied to a State.

If you want to quickly see the mathematical operations on Quantum States using gates, then wrelks-quirk is a great starting point for you.

Defining features:

• Runs in web browsers.
• Drag-and-drop circuit editing.
• Reacts, displays, and computes in real time.
• States are rendered in LaTeX.

Notable limitations:

• Currently the engine can only render one qubit
• Only basic gates such as X,Y,Z, and Hadamard gates can be used.
