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…

Formation of a lateral p-n junction light-emitting diode on an n-type high-mobility GaAs/AlGaAs heterostructure
C. P. Dobney, A. Nasir, P. See +5
We have fabricated a device which includes two lateral p-n junctions on an n-type GaAs/AlGaAs heterostructure. A section of the n-type material has been converted…
