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]
