For higher education & research

Learn quantum computing by doing.

Anjung Quantum Simulator brings quantum computing into the browser. Build a circuit, run it on a simulated quantum computer, and see exactly what every gate does — live, as you build.

The challenge

Quantum skills are in demand. Hands-on access is not.

Theory-heavy courses

Students meet qubits as equations long before they ever see one behave.

Scarce hardware time

Real devices mean accounts, queues and noise that hide the core ideas.

A steep tooling curve

Code-first SDKs ask newcomers to learn programming and physics at once.

The result: learners struggle to build intuition, and lecturers struggle to make quantum concepts tangible.

The solution

A quantum lab that fits in a browser tab

Everything an ideal quantum computer does — superposition, interference, entanglement, measurement — rendered as something you can watch and change. No queue, no SDK, no setup.

Learn by doing, not by memorising.

Capabilities

Everything a learner needs to explore

Build circuits visually

Place any of 15 gates on up to 5 qubit wires and compose circuits before writing a line of code.

Open the workbench →

Watch the state evolve

Inspect amplitudes, phases, probabilities and a Bloch sphere per qubit as each gate acts.

See entanglement →

Learn step by step

Guided exercises move from one qubit to superposition, entanglement and Grover's search.

Runs in the browser

No installation and no hardware queue. Open qsim.my and start — nothing to configure.

How it works

Four steps from idea to insight

Build

Drag gates onto qubits to design a circuit.

Simulate

Run it instantly on a simulated quantum computer.

Inspect

Read the state, probabilities and measurement results.

Iterate

Change a gate, rerun, and build intuition by experiment.

Every experiment can be repeated in seconds, so curiosity costs nothing.

For educators

A quantum lab for every classroom

Turn abstract lectures into hands-on sessions, whatever the class size.

Live lecture demonstrations
Show superposition and entanglement happening, not just on the whiteboard.
Lab sessions and tutorials
Give every student their own simulator, with no hardware to schedule.
Assignments and self-study
Set circuit-building tasks students can complete anywhere.
Workshops and short courses
Run hands-on bootcamps for students and staff new to quantum.

For researchers

A sandbox for quantum research

Think out loud in circuits before you spend time on real devices.

Prototype ideas

Test algorithm ideas on an ideal simulator before committing time on real hardware.

Onboard new lab members

Bring students up to speed on circuits and notation through practice.

A common language

Discuss and compare circuits with collaborators in one shared tool.

Simulation capacity

Up to 5 qubits and 32 amplitudes, re-simulated exactly on every edit — no sampling noise.

Guided learning

Lessons that teach through action

Short tasks guide students to build the circuit themselves, then reflect on what the results mean. 13 lessons run from “what is a qubit” to error correction, each wired into a live circuit you can modify.

Clear goals for each step
Instant visual feedback
Concepts linked to results

Start lesson 1

1What is a qubit? — The quantum bit: like a coin that can be heads, tails, or a precise blend of both.6 min 2Superposition & the Hadamard gate — How one gate turns certainty into a perfect quantum coin flip — and why that's not randomness.7 min 3The gate zoo — X, Y, Z, phase gates and rotations — every gate is just a rotation of the Bloch sphere.8 min 4Entanglement & Bell states — Two qubits that share a single fate — the phenomenon Einstein called 'spooky'.8 min 5Measurement & probability — Why looking changes everything, and what 1024 shots on real hardware actually mean.6 min 6Famous circuits: Grover & teleportation — Two small circuits with big ideas: searching faster than brute force, and moving states without moving matter.9 min 7The no-cloning theorem — Why quantum information can be moved but never copied — and why that's a feature.5 min 8Superdense coding — Send two classical bits by transmitting a single qubit — entanglement pays the difference.6 min 9Deutsch's algorithm — The first quantum algorithm: answer a question about two function values with a single query.8 min 10Bell's inequality — The experiment that proved measurement outcomes don't exist before you measure.9 min 11Quantum cryptography: BB84 — How single qubits let two people build a secret key that physics itself protects.8 min 12Quantum error correction — Protecting fragile superpositions without ever looking at them.8 min 13What quantum computers can and can't do — Shor, Grover, simulation — and why 'tries every answer at once' is a myth.7 min
