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, such number-path entanglement has thought to have been resource intensi

Encoding qubits into oscillators with atomic ensembles and squeezed light
Autor: Keith R. Motes, Ben Q. Baragiola, Nicolas C. Menicucci, Alexei Gilchrist
Publikováno v: Physical Review A. 95
The Gottesman-Kitaev-Preskill (GKP) encoding of a qubit within an oscillator provides a number of advantages when used in a fault-tolerant architecture for quantum computing, most notably that Gaussian operations suffice to implement all single- and

Efficient recycling strategies for preparing large Fock states from single-photon sources --- Applications to quantum metrology
Autor: Keith R. Motes, Jonathan P. Olson, Peter P. Rohde, E. Annelise Bergeron, Jonathan P. Dowling, Dominic W. Berry, Ryan L. Mann, Alexei Gilchrist, Nicholas M. Studer
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 Fock states with large photon number remains challenging. We present and

Quantum random walks on congested lattices and the effect of dephasing
Autor: Keith R. Motes, Peter P. Rohde, Alexei Gilchrist
Publikováno v: Scientific Reports
We consider quantum random walks on congested lattices and contrast them to classical random walks. Congestion is modelled with lattices that contain static defects which reverse the walker's direction. We implement a dephasing process after each ste

Adaptive phase estimation with two-mode squeezed-vacuum and parity measurement
Autor: Keith R. Motes, Petr M. Anisimov, Jonathan P. Dowling, Zixin Huang, Dominic W. Berry
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 Cram\'{e}r-Rao sensitivity is sub-Heisenberg [Phys.\ Rev.\ Lett.\ {\bf104}, 103602 (2

Implementing Scalable Boson Sampling with Time-Bin Encoding: Analysis of Loss, Mode Mismatch, and Time Jitter
Autor: Alexei Gilchrist, Peter P. Rohde, Keith R. Motes, Jonathan P. Dowling
It was recently shown by Motes, Gilchrist, Dowling & Rohde [PRL 113, 120501 (2014)] that a time-bin encoded fiber-loop architecture can implement an arbitrary passive linear optics transformation. This was shown in the case of an ideal scheme whereby
