  Paw{\l}owski and Winter's hyperbit theory, proposed in 2012, presented itself
as an alternative to quantum theory, suggesting novel ways of redefining
entanglement and classical communication paradigms. This research undertakes a
meticulous reevaluation of hyperbit theory, uncovering significant operational
constraints that question its equivalence with quantum mechanics. Crucially,
the supposition that hyperbit theory and quantum theory are equivalent relies
on the receiver having unattainable additional knowledge about the sender's
laboratory, indicating that the work by Pawlowski and Winter is incorrect. This
study accentuates the constraints of hyperbits in information processing and
sheds light on the superiority of quantum communication, thereby advancing the
investigation at the intersection of classical and quantum communication.
