Quantum101
Qubits, superposition and measurement, built from scratch and demonstrated live in Qiskit.
Qiskit Fall Fest 2026
Try it
Press a gate. The qubit moves. Everything below is real linear algebra — the same 2×2 matrices Qiskit applies, running in your browser.

The programme
Each one stands alone. Quantum101 → Hackathon is the route we would take.
Dates, times and venues are confirmed. Register your interest and we will email you a reminder before each session.
Qubits, superposition and measurement, built from scratch and demonstrated live in Qiskit.
Someone from the quantum industry on where the field actually is, and what has been oversold.
An IIT Bombay faculty view of the physics under the abstraction — how a qubit is built and kept coherent.
Teams, a problem statement, mentors, and access to IBM Quantum hardware. 36 hours, non-stop. Prep material is below.
A walk through the hardware and instrumentation on campus, then results and closing remarks.
Where it runs
Hackathon circuits are queued to an IBM superconducting processor — transmons on a heavy-hex lattice, held near 15 millikelvin. This is the shape of one.
Bell state · H then CNOT · 1024 shots
Two qubits, entangled. Neither one has a value of its own — but they always agree. The stray counts in the middle two rows are readout error, and on real hardware they never quite reach zero.
Resources
All free, all link-checked. Session slides and notebooks land here as the fest runs.
Free. Get your API token before Quantum101 so you are not setting up during the session.
quantum.cloud.ibm.com ↗SetupVirtual environment, pip install qiskit, Jupyter. 64-bit only from v2.0.
quantum.cloud.ibm.com/docs ↗OverviewThe SDK, the transpiler, the primitives, and the runtime that ties them together.
ibm.com/quantum/qiskit ↗Course hubSuccessor to the old Qiskit Textbook — ten-plus free courses with runnable code.
quantum.cloud.ibm.com/learning ↗CourseJohn Watrous. The single best foundation if you want the maths done properly.
quantum.cloud.ibm.com/learning ↗Lecture seriesGraduate-level lectures, free. The natural next step after the fest.
youtube.com ↗DocsAPI reference, transpilation guides, error mitigation. Keep this tab open at the hackathon.
quantum.cloud.ibm.com/docs ↗NotebooksEnd-to-end: CHSH, QAOA, VQE, quantum kernels, Grover, Shor. Steal the patterns.
quantum.cloud.ibm.com/docs/tutorials ↗SourcePython with a Rust core. The changelog is the fastest way to find what a function really does.
github.com/Qiskit/qiskit ↗Best practice setLabs 0–4 plus a bonus, auto-graded, solutions in the repo. Do this one before the hackathon.
github.com/qiskit-community ↗PracticeMore recent, closer to the current Qiskit 2.x API than the older challenge sets.
github.com/qiskit-community ↗ToolInstall it and the challenge notebooks above will check your answers as you go.
github.com/qiskit-community ↗LibrariesCommunity tools that plug into Qiskit — chemistry, optimisation, ML, visualisation.

Anything missing, mail the organising team — the address is at the bottom.
Any IIT Bombay student, any department, any year — undergraduate, postgraduate or PhD. Access for participants from outside campus will be confirmed alongside the schedule.
No. Quantum101 assumes complex numbers and a Python loop. Everything else is built from there.
Enough to write a function and a loop. If you have used NumPy once, you are comfortably ahead.
Yes. A free IBM Quantum account puts your circuits on real superconducting processors. You will see the noise, the queue and the counts for yourself.
Yes. Each session stands on its own. The hackathon assumes Quantum101, so do that one first if you can.
A laptop with Python and Qiskit installed, and an IBM Quantum account. Both links are in Resources.
Every session is free. Places at the hackathon and the lab visits may be limited by room capacity, so registration order will matter for those.
