Query: Testing Quantum Origin of Primordial Gravitational Waves and Magnetic
  Field   Universe is believed to be born out of a quantum state. However, defining any
observables associated the quantum properties and their possible observational
possibilities in the present universe has gained significant interest recently.
In this submission we propose quantum Poincare sphere measurement as an
observable quantity which can give us hint of quantumness of the origin of
primordial gravitational waves and large scale magnetic field. The Poincare
sphere is defined in terms of power spectrum and quantum stokes operators
associated with the polarization of those fields, which can be directly
measured. To support our results we further explored the possible Bell
violation test for a set of generalized pseudo spin operators defined in the
polarization space of those fields.
