A protocol with two generalized measurements prepares versatile probe states from thermal qubits to enhance quantum Fisher information for decay rate and temperature estimation in amplitude damping channels, deriving an analytical link to thermodynamic susceptibilities and Hamiltonian variance valid
Sub-resonant charge cycling of NV centers arises from phonon-assisted anti-Stokes excitation, with low-energy acoustic phonons near the ZPL and a 43 meV mode at longer wavelengths contributing most.
