Ket Steps
Read full descriptionHide full description
Ket Steps is a symbolic workpad for quantum states. Define kets, bras, and operators in standard bra-ket notation, compose them, and get exact results (fractions, imaginary units, and ...) without numeric approximation unless you ask for it. Each line is a typed, labeled object. Select two, apply an operation, and the result appears contrasted against the input for quick validation, not just the answer. Every result exports to LaTeX with a single tap. **What it does today** Single- and multi-qubit states, tensor products, standard operators (Pauli X/Y/Z, Hadamard, and more), inner products, outer products, and operator-ket application. Exact symbolic arithmetic throughout. Norm validation on every state. A growing library of named objects to insert with one tap. **Where it's going** Ket Steps aims to become a complete toolkit for quantum information theory. Join our Kets on their journey. **Privacy** Everything stays on your device. No data is collected, transmitted, or stored anywhere else.
