Your quantum learning path
Move from a single qubit to algorithms and communication in five guided stages.

Choose where to begin
View learning path→
Choose a quantum experiment
Start with foundations, then move toward entanglement, communication and algorithms.
Choose the right computing approach
Start with a real task, change its conditions, and see when CPU, GPU or QPU becomes the right fit.
There is no universal winner. Every result separates measured, simulated, theoretical and recorded evidence.
How to read the evidence
Source labels tell you whether a value came from this device, a teaching model, complexity analysis or a saved QPU run.
- Measured
- Simulated
- Theoretical
- Recorded QPU

How to use Qubimi
- 1
Understand the purpose and review the plan.
- 2
Predict the result before measuring.
- 3
Adjust the main control and measurement count, then run the experiment.
- 4
Compare the expected distribution with the sampled results, then watch the explanation.
- 5
Complete the understanding check.
03 · Reading the results
Expected and sampled results tell two parts of the story.
The expected pattern shows the underlying probability. A sampled run shows what happened in a finite set of measurements.
Expected pattern
The smooth theoretical balance for the control value you chose.
Expected pattern: |0⟩ 50%, |1⟩ 50%.
Sampled run
A local simulation of a limited number of measurements, so the bars may move slightly.
Sampled run: |0⟩ 47%, |1⟩ 53%.
More measurements usually bring the sampled bars closer to the expected pattern.

Progress stays with you
Qubimi remembers completed lessons and your last experimental setting, so you can continue from the home page or library.
Progress is stored only in this browser on this device. No account is required, and clearing browser storage removes it.
Progress and privacyLearning progress is stored only on this device. Qubimi uses Google Analytics to understand aggregate site usage; Analytics is not used to sync learning progress.
05
Learn with every experiment
The guided video appears after you complete one measurement. Narration and subtitles are in English in every interface language.
Use the controls your way
Qubimi works with a keyboard, touch, or mouse. Use Tab to move, Enter or Space to activate, and the arrow keys to adjust sliders.

Small quantum glossary
- Qubit
- A quantum information unit. Unlike a classical bit, its state can include amplitudes for both 0 and 1.
- Gate
- A controlled operation that rotates or correlates quantum states.
- Amplitude
- A signed or complex quantity whose squared size becomes a measurement probability.
- Measurement
- The act that records a classical result such as 0 or 1.
- Entanglement
- A joint state whose parts cannot be fully described independently.

Common questions
Is this a real quantum computer?
No. Qubimi is a visual teaching simulator. It demonstrates idealized behavior so the main idea stays visible.
Why do results change when I run again?
Quantum measurement is probabilistic. A finite sample moves slightly even when the underlying probability is unchanged.
Where should I begin?
Complete the experiments in order so each new idea builds on the last. After Stage 3, you can take Stage 4 or Stage 5 first.
Do I need to know equations?
No. Every experiment begins with a visual explanation; notation is introduced only where it helps.
