Controllable entangled state distribution in a dual-rail reconfigurable optical network
Shuto Osawa, David S. Simon, Vladimir S. Malinovsky +1
Reconfigurable distribution of entangled states is essential for operation of quantum networks connecting multiple devices such as quantum memories and quantum computers. We introd…
Higher-dimensional Hong-Ou-Mandel effect and state redistribution with linear-optical multiports
Shuto Osawa, David S. Simon, Alexander V. Sergienko
We expand the two-photon Hong-Ou-Mandel (HOM) effect onto a higher-dimensional set of spatial modes and introduce an effect that allows controllable redistribution of quantum state…
Quantum-Clustered Two-Photon Walks
David S. Simon, Shuto Osawa, Alexander V. Sergienko
We demonstrate a previously unknown two-photon effect in a discrete-time quantum walk. Two identical bosons with no mutual interactions nonetheless can remain clustered together as…
Directionally-Unbiased Unitary Optical Devices in Discrete-Time Quantum Walks
Shuto Osawa, David S. Simon, Alexander V. Sergienko
The optical beam splitter is a widely-used device in photonics-based quantum information processing. Specifically, linear optical networks demand large numbers of beam splitters fo…
Experimental demonstration of a directionally-unbiased linear-optical multiport
Shuto Osawa, David S. Simon, Alexander V. Sergienko
All existing optical quantum walk approaches are based on the use of beamsplitters and multiple paths to explore the multitude of unitary transformations of quantum amplitudes in a…
Joint Entanglement of Topology and Polarization Enables Error-Protected Quantum Registers
David S. Simon, Shuto Osawa, Alexander V. Sergienko
Linear-optical systems can implement photonic quantum walks that simulate systems with nontrivial topological properties. Here, such photonic walks are used to jointly entangle pol…
Topological Transitions and Bulk Wavefunctions in the SSH Model
David S. Simon, Shuto Osawa, Alexander V. Sergienko
Working in the context of the Su-Schreiffer-Heeger (SSH) model, the effect of topological transitions on the structure and properties of bulk position-space wavefunctions is studie…
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…
