AriQuantum: Как я написал эмулятор квантового компьютера прямо в Telegram

Квантовые вычисления – это сложно. Сложная математика, сложные инструменты, и всё это только в рамках вузовских программ. Я решил это исправить и сделал эмулятор квантовых схем прямо в Telegram – бесплатно, без установки, только кнопки. Внутри статьи – история создания, технические подробности и демонстрация работы. Изучать кванты

#ITByte: A #Quantum #Circuit is a model for quantum computation, similar to classical circuits, in which a computation is a sequence of quantum gates, measurements, initializations of qubits to known values, and possibly other actions.

Developing your first #Quantum #Circuit - get started with Hands-on Programming for Quantum Computers using IBM #Qiskit.

Been learning quantum on the side for months. What tripped me up wasn't the math — it was how often "canonical" circuits from papers and tutorials fail quietly. Broken Hamiltonians. Reversed bit orders. Silent API drift.

So I built a personal library where every circuit is checked against its reference output before it's listed. 50+ curated circuits across Qiskit, PennyLane, and Cirq. No signup required.

QubitHub's quantum circuit library is open to browse — https://qubithub.co?utm_source=mastodon&utm_medium=social&utm_campaign=m25-library-open

50+ curated circuits (Qiskit, PennyLane, Cirq). Every one audited against its reference output. No signup required to browse — readable URLs like https://qubithub.co/qubithub/grover-search?utm_source=mastodon&utm_medium=social&utm_campaign=m25-library-open , no UUIDs.

Sign-up's open. Creating circuits is invite-only for now (drop me a line after sign-up). In-browser execution is coming next.

Writing my first quantum computing experiments (simulated only for now, using IBM Qiskit). It’s great to be collaborating again with my former undergraduate research advisor and his students... Almost 20 years after graduation. Some light academic work makes me very happy. One day I’ll still go back and finish my Master’s... I've dropped out twice, third time's the charm :)

Updated: I added the aha-chapter that I was missing.

"Quantum computers try all possibilities in parallel" is the popular line — and it's dangerously misleading. A measurement collapses everything to one random answer, so "parallel" on its own is useless.

The actual move: a quantum algorithm is ONE global linear transformation on a 2^n-amplitude vector, designed so wrong answers destructively cancel and the right one amplifies. Classical searches. Quantum shapes.

Walkthrough with a Grover-style bar chart in four snapshots, plus the full pipeline: superconducting oscillator → Josephson junction → Bell state → amplitude amplification → Shor / Grover / simulation.

Circuit spotlight: Quantum Teleportation

Transfers an unknown quantum state between qubits using a shared Bell pair and 2 classical bits.

Alice entangles her message with her half, measures, sends 2 bits to Bob. Bob applies X/Z corrections to reconstruct the state.

No FTL. Original destroyed. Entanglement consumed.

Circuit spotlight: VQE — H₂ Ground State

Parameterized quantum circuit + classical optimizer → molecular ground-state energy.

For H₂: 2 qubits, 4 parameters, converges to -1.137 Hartree — near the exact FCI/STO-3G result. Only 2 measurement bases needed (ZZ and XX).

Circuit spotlight: Grover's Search (1996)

Finds a marked item in an unsorted database with quadratic speedup — O(√N) queries instead of O(N).

For 2 qubits: 1 oracle query, 1 diffusion step, 100% success on a simulator. One iteration is all this special case needs.

Oracle flips a phase. Diffusion amplifies it. Interference does the rest.

Circuit spotlight: Bell State

Creates |Φ+⟩ = (|00⟩ + |11⟩)/√2 — the simplest entangled state.

Two gates. Two qubits. One of quantum mechanics' deepest phenomena.
