quantum entanglement - 2025 VAULT II

Packet 5: Bonus 1

Answer the following about the CNOT (“c-not”) gate. For 10 points each:

[10m] A CNOT gate creates this phenomenon by making two bits inseparably correlated through conditional flipping. The EPR paradox holds states with this property imply hidden variable theories.

ANSWER: quantum entanglement [or entangled states]

[10h] In quantum computing, a CNOT (“c-not”) gate can be analogized to a reversible one of these gates. Performing this logical operation three times can swap a variable without using a temp.

ANSWER: XOR (“X-or” but be generous on pronunciation) [or EOR or EXOR or exclusive or or exclusive disjunction; accept logical inequality or NEQ; prompt on addition modulo 2; reject “OR”]

[10e] This proper adjective, named for an English mathematician, describes expressions formed by logic gates like CNOT that output “true” or “false.”

ANSWER: Boolean expressions [or booleans]
