Experimental quantum state learning with pairs of photons
C. Pria Dobney, Johan Henaff, Allen Kasum +5
Tomography allows one to estimate the density matrix describing the state an ensemble of quantum systems are prepared in (for example, polarization tomography determines the polari…

Compressing Quantum Fisher Information
Rui Jie Tang, Jeremy Guenza Marcus, Noah Lupu-Gladstein +5
We show that the quantum Fisher information about any phase parameter encoded in a family of pure quantum states can be faithfully compressed into a single qubit, accompanied by a…
