trick-or-treat
Explanation
The Joke
A couple is dealing with their young daughter ahead of Halloween. The father says "Hey honey, we need to get candy for Halloween!" and the daughter immediately starts chanting "Candy! Candy!" The mother notes that their daughter (named Danni) has managed to decrypt their language, and she'll have to use a more advanced code next time. The father then tries spelling it out: "Hey honey, we need to get C-A-N-D-Y for Halloween!" The daughter again exclaims "Candy! I want candy!" The father, exasperated, tries an even more complex encoding, using a string of random-looking characters. The daughter responds with "Candy now!" The mother angrily demands to know: "Dammit, who taught her Shor's algorithm?"
The Humor
The comic escalates a common parenting situation — spelling out words so young children don't understand — into a computer science joke. When simple spelling fails, the father apparently resorts to encryption (the garbled string of characters). But the child still understands, prompting the mother to ask who taught her Shor's algorithm. Shor's algorithm is a quantum computing algorithm that can break most modern encryption schemes. The joke is that the toddler has somehow mastered quantum computing, making her capable of decrypting any encoded message about candy. The humor works on multiple levels: the relatable parenting frustration, the absurdity of a toddler knowing quantum computing, and the implication that the desire for candy is a sufficiently powerful motivation to break any code.

It is one of the main reasons quantum computing is considered a potential threat to modern cybersecurity.
