Leren: het curriculum

Een geordend leerpad, geen blogarchief. Het begint met intuïtie voor lineaire algebra — de echte basiskennis die de meeste bronnen overslaan — en eindigt met wat kwantumcomputers aantoonbaar níét kunnen. Vereisten worden getoond; je voortgang wordt bijgehouden in je browser.

Gevulde markers zijn stappen die je al hebt doorlopen; de open ring is waar je nu bent. Pijlen tonen vereisten. Tik op een stap om er direct naartoe te gaan.

Elke stap vermeldt waar de inhoud op jouw niveau te vinden is: de vriendelijke lessen voor Nieuwsgierig, de intermediaire Academy-cursus voor Technisch, de gevorderde cursus voor Expert. Wissel van niveau via de header, op elk moment.

Linear algebra intuition

Vectors, bases, matrices as transformations, and tensor products. The ACTUAL prerequisite for quantum computing, which most resources skip.

2 A cold-atom experiment at Jagiellonian University: atoms cooled to where superposition rules. Tomasz Kawalec · CC BY-SA 4.0 ↗

Qubits and superposition

From the definite bit to the amplitude-carrying qubit. Why '0 and 1 at the same time' is a shortcut, not the truth.

Vereiste voorkennis: linear algebra intuition

3 today's quantum forecast 🌤️ 70% heads 30% tails before you measure, the odds are ALL anyone can know, even nature

Measurement

One classical outcome per shot; the distribution is the output. Why looking changes things, and why algorithms repeat.

Vereiste voorkennis: qubits superposition

4 the spooky link measured: H instantly: H too any distance apart: across a room or across a galaxy

Entanglement

Joint structure no independent description reproduces: a resource, not a faster-than-light telephone.

Vereiste voorkennis: measurement

5 A NIST ion trap: quantum logic gates were first demonstrated on trapped ions. NIST · Public domain ↗

Gates and circuits

X, Z, H, rotations and CNOT; circuits as time-ordered choreography; why compilation to real hardware changes everything.

Vereiste voorkennis: qubits superposition

6 Tonomura's double-slit experiment: single electrons building an interference pattern. A. Tonomura / Belsazar · CC BY-SA 3.0 ↗

Interference: the actual source of advantage

Wrong answers cancel, right answers reinforce. The one-sentence truth of quantum speedup lives here.

Vereiste voorkennis: gates circuits

7 CLASSICAL the best available algorithm, step by step QUANTUM amplitudes over paths: wrong paths cancel the useful comparison is not "one path versus all paths" but the best algorithm available per problem

The major algorithms

Deutsch-Jozsa for intuition, Grover for search, Shor for cryptography: each with its honest reality check.

Vereiste voorkennis: interference

8 room temperature up here 🌡️ each layer: colder… …and colder… the chip: colder than space 🥶 ~0.01° above absolute zero "the chandelier": mostly a very fancy fridge

Decoherence and noise

Why qubits are divas, what T1/T2 mean, and why the useful life of quantum information is finite.

Vereiste voorkennis: gates circuits

9 PHYSICAL QUBITS noisy · error-prone · many error-correcting code + decoding ONE LOGICAL QUBIT reliable · what algorithms see one logical qubit may need hundreds or thousands of physical qubits plus classical control

Error correction and logical qubits

Many noisy physical qubits become one dependable logical qubit, and 'below threshold' becomes the field's honest scoreboard.

Vereiste voorkennis: decoherence noise

10 STRONG AT · simulating molecules · best-combo searches · (someday) code-breaking NOT BUILT FOR · loading websites · running your games · email, spreadsheets, apps a specialist tool, not a better laptop

What quantum computers provably cannot do

The most common misconception in the field, treated head-on: quantum computers do NOT try all answers in parallel. Interference is the mechanism.

Vereiste voorkennis: interference, major algorithms
