The continued popularity of Red Delicious despite objectively better alternatives is the best metaphor for the state of our democracy I've seen in a while. (source: sherwood.news)
Any set of physical qubits can even host exponentially many (crappy) logical qubits! arxiv.org/abs/1701.01062 Please don't tell any marketing departments of QC startups.
Overlapping qubits
An ideal system of $n$ qubits has $2^n$ dimensions. This exponential grants power, but also hinders characterizing the system's state and dynamics. We study a new problem: the qubits in a physical sys...

I still often reflect back on this information diagrams to help boost my intuition about the local information content of entangled systems: Cerfa, Nicolas J., and Chris Adamib. "Quantum information theory of entanglement and measurement." arXiv preprint quant-ph/9605039 (1997).

I've never seen so much effort put into making a 'quantum money' figure! From Adrian Kent's portion of "ISOLATION – solitude, secrets, atoms . . ."
I've always enjoyed tetrahedron representations of two-qubit states: Salazar, Roberto, et al. "Quantum Resource Theories beyond Convexity." arXiv preprint arXiv:2405.05785 (2024).
Unfortunately, they changed the title (see version 2 on the arXiv for this one), but before the change, it had one of the most stunning titles I've ever seen for a physics paper:
Budroni, Costantino, et al. "Kochen-specker contextuality." Reviews of Modern Physics 94.4 (2022): 045007.
