Exercise #1: “Hello World” with 1 qubit and simulator

A beginner’s quantum computing exercise demonstrates a single-qubit "Hello World" using a Hadamard gate to introduce superposition, mirroring classical programming’s first-step tradition. The exercise targets novices, offering a minimalist approach to quantum computation by applying a Hadamard gate to one qubit, producing an equal superposition of |0⟩ and |1⟩ states. Published in February 2026, the discussion questions whether the exercise is sufficiently detailed or needs expansion, particularly in explaining superposition’s broader implications or practical applications. The author suggests potential multilingual publication, hinting at broader accessibility goals but without specifying implementation plans or target languages for global outreach. Critics note the simplicity may limit depth, though it effectively serves as a foundational introduction for those new to quantum circuits and simulation tools.
