👉 In the context of quantum physics, a Pauli spin-singlet state (or Pauli spindling) is a special type of quantum state that describes a system where two electrons are in a superposition of spin states. This state is known as a "Pauli spin-singlet state" because it represents a singlet state with the spins aligned and opposite each other, but not necessarily in the same direction. The Pauli spin-singlet state can be described using the tensor
