Quantum simulation of topologically protected states using directionally unbiased linear-optical multiports
David S. Simon, Casey A. Fitzpatrick, Shuto Osawa +1
It is shown that quantum walks on one-dimensional arrays of special linear-optical units allow the simulation of discrete-time Hamiltonian systems with distinct topological phases.…
Quantum simulation of discrete-time Hamiltonians using directionally unbiased linear optical multiports
David S. Simon, Casey A. Fitzpatrick, Shuto Osawa +1
Recently, a generalization of the standard optical multiport was proposed [Phys. Rev. A 93, 043845 (2016)]. These directionally unbiased multiports allow photons to reverse directi…
Group transformations and entangled-state quantum gates with directionally unbiased linear-optical multiports
David S. Simon, Casey A. Fitzpatrick, Alexander V. Sergienko
The concept of directionally unbiased optical multiports is introduced, in which photons may reflect back out the input direction. A linear-optical implementation is described, and…
Discrimination and synthesis of recursive quantum states in high-dimensional Hilbert spaces
David S. Simon, Casey A. Fitzpatrick, Alexander V. Sergienko
We propose an interferometric method for statistically discriminating between nonorthogonal states in high dimensional Hilbert spaces for use in quantum information processing. The…
Security in the Multi-Dimensional Fibonacci Protocol
David S. Simon, Casey Fitzpatrick, Alexander V. Sergienko
Security against simple eavesdropping attacks is demonstrated for a recently proposed quantum key distribution protocol which uses the Fibonacci recursion relation to enable high-c…
High Capacity Imaging and Rotationally Insensitive Object Identification with Correlated Orbital Angular Momentum States
Casey A. Fitzpatrick, David S. Simon, Alexander V. Sergienko
Using no conventional measurements in position space, information extraction rates exceeding one bit per photon are achieved by employing high-dimensional correlated orbital angula…
