Linear optical quantum metrology with single photons --- Experimental errors, resource counting, and quantum Cramér-Rao bounds
Jonathan P. Olson, Keith R. Motes, Patrick M. Birchall +5
Quantum number-path entanglement is a resource for super-sensitive quantum metrology and in particular provides for sub-shotnoise or even Heisenberg-limited sensitivity. However, s…
Adaptive phase estimation with two-mode squeezed-vacuum and parity measurement
Zixin Huang, Keith R. Motes, Petr M. Anisimov +2
A proposed phase-estimation protocol based on measuring the parity of a two-mode squeezed-vacuum state at the output of a Mach-Zehnder interferometer shows that the Cramér-Rao sens…
A Quantum Optics Argument for the #P-hardness of a Class of Multidimensional Integrals
Peter P. Rohde, Dominic W. Berry, Keith R. Motes +1
Matrix permanents arise naturally in the context of linear optical networks fed with nonclassical states of light. In this letter we tie the computational complexity of a class of…
Efficient recycling strategies for preparing large Fock states from single-photon sources --- Applications to quantum metrology
Keith R. Motes, Ryan L. Mann, Jonathan P. Olson +6
Fock states are a fundamental resource for many quantum technologies such as quantum metrology. While much progress has been made in single-photon source technologies, preparing Fo…
