Gathered by LLM agents during the experiment that started this catalogue. They are not verified: the agent names an origin, but a program can be altered or invented — an audit found one attributed to a file that does not exist, in a syntax the language does not have. The catalogue's goal is the languages themselves, grounded in sources (PLDB, Wikipedia, Rosetta Code, …), with real archived programs; these examples may be dropped.

# Bell State Preparation
# This program creates a maximally entangled Bell state between two qubits

DECLARE ro BIT[2]

# Initialize qubit 0 in superposition
H 0

# Entangle qubit 0 and qubit 1
CNOT 0 1

# Measure both qubits
MEASURE 0 ro[0]
MEASURE 1 ro[1]
