qbit

A quantum state in a 2-dimensional Hilbert space of states.

In geometric quantization qbits are naturally understood as the states given by the geometric quantization of the 2-sphere for prequantum line bundle (plus metaplectic correction) being of unit first Chern class. See at *geometric quantization of the 2-sphere – The space of quantum states*.
