Hi, this is my humble suggestion for a QBIT logo. The two arrows represent the superposition of two quantum states (spin, polarization, etc.) that is the qubit. I was going to add a bra-ket notation for the wave function but it might not appeal to the masses. Or put both arrows inside a ket for entangled states.....But simplicity=elegance=mass appeal. If the community like the concept, we need a real graphics artist to redo the colors, shapes, proportions, etc....This is all I could muster from Powerpoint with my limited artistic ability
