In quantum computing, particularly when discussing the Bloch sphere representation, poles refer to the two extreme points on the sphere that correspond to the logical states of a qubit. These poles represent the basis states |0⟩ and |1⟩, which are fundamental to quantum information processing. The orientation of a qubit on the Bloch sphere is determined by the angles around the sphere, and understanding poles helps in visualizing quantum state superpositions and measurements.
congrats on reading the definition of poles. now let's actually learn it.
