We are working on a cut-out book with interactive gates and measurement devices to teach quantum computing. Would you be interested in using something like this, and if so, what age group would you use this for?

By shifting the wave function we can get cancellation and amplification effects, similar to what is used for signal processing and sound engineering. These effects, which require additional computation on a classical computer, can be put to good use in quantum algorithms.

Quantum leaps are discrete beacuse they behave like stationary waves. Here we have 3 qubits on a single saxophone! (Pierre-Stéphane Meugé at Studio Sequenza)

His book "Mathematica" is a real eye-opener. David Bessis describes accurately and vividly the way we perceive and manipulate mathematical objects. Colleagues who read it also felt he put into words what they had not been able to formulate about the mathematical process. Highly recommended.

Here's that quote from Einstein's 1940 Science paper, "Considerations concerning the Fundaments of Theoretical Physics".
The next step was taken by De Broglie. He asked
himself how the discrete states could be understood by
the aid of the current concepts, and hit on a parallel
with stationary waves, as for instance in the case of
the proper frequencies of organ pipes and strings in
acoustics. True, wave actions of the kind here re-
quired were unknown; but they could be constructed,and their mathematical laws formulated, employing
Planck's constant h. De Broglie conceived an electron
revolving about the atomic nucleus as being connected
with such a hypothetical wave train, and made intel-
ligible to some extent the discrete character of Bohr's
"permitted" paths by the stationary character of the
corresponding waves.

Who knew? A quote from David Sulzer’s Math Music and Mind on how harmonics in music inspired de Broglie’s view of quanta.

It's easier to understand quantum algorithms if you think of qubits as waves with an amplitude and a phase. Come play with our music installation u-paris.fr/sciences/%C3...

In any execution, there is only a small probability that your marble has reached the exit of the maze. The same goes for quantum algorithms. Parallel executions don't help unless you can amplify the probability of getting a correct answer in the end. This is where much of the power of quantum lies.
010
QuBobs @qubobs.bsky.social · 27/05/2025
If you want to describe the location of a marble in a maze at a given time, you could describe it as being in all possible locations, with some probability. This sounds a lot like "massive parallelism", but there's nothing strange or quantum about it.
100
QuBobs @qubobs.bsky.social · 27/05/2025
To demystify the notion that quantum computing owes its advantage to "massive parallelism" I find it useful to compare it to a random walk in a maze. A marble can explore many paths in the maze...
