Page 19, author needs to define "state" ...
"Because the bits in classical computing can hold only one of two values — a 0 or a 1 — at the same time, the number of states that a classical computer can hold is represented by the number of bits, n, to the power of two: n^2. But a set of entangled qubits can hold all the possible values of the qubits at the same time. For this reason, the number of states that a quantum computer can hold is represented by two to the power of qubits, n: 2^n. "
The number of states for a classical computer should be 2^n - much bigger than n^2.
If I am wrong, then please convince me by listing for n = 5:
the 25 (5^2) classical states and the 32 (2^5) quantum states.

...
"1, 3, 5, and 7 are all prime numbers."
1 IS NOT A PRIME NUMBER!!!!!!!!
FFS!

Could have been more technical.

Provided a great overview of the quantum computing, however two expansions afterwards: learning Qiskit & learning advanced quantum mechanics… oopsie that’s enough of planning for today time to sleep or work

Not many math or science details, but it did cover how quantum annealing is different general qbit gates. Also includes a survey of companies and universities currently involved int quantum computing.

Very little to learn, essentially a long form advertisement

Nicht schlecht, aber viele Konzepte werden zu schnell abgearbeitet. So zum Beispiel Verschränkung oder Superposition. Ich verstehe, die Konzepte sind nicht einfach zu verstehen und noch schwieriger zu erklären. Aber es wird zu wenig angeboten. Wenn einem die Erklärweise des Authors nicht passt, hat man Pech gehabt. Von einem "für Dummies" Buch hätte ich mir mehr Metaphern, mehr Brücken, mehr Beispiele gewünscht um wirklich ein Gefühl für die Theorien zu entwickeln.
Als Ergänzung kann ich dafür "Warum wir nicht durch Wände gehen: Unsere Teilchen aber schon" von Florian Aigner empfehlen.
