Single-photon description of the lossless optical Y coupler
Christopher R. Schwarze, Anthony D. Manni, David S. Simon +1
Using symmetry considerations, we derive a unitary scattering matrix for a three-port optical Y-coupler or Y-branch. The result is shown to be unique up to external phase shifts. U…
Enhanced-sensitivity interferometry with phase-sensitive unbiased multiports
Christopher R. Schwarze, David S. Simon, Alexander V. Sergienko
Here we introduce interferometric devices by combining optical feedback (cavities) with unbiased multiports, which unlike traditional beam dividers, allow light to reflect back out…
Interferometry and higher-dimensional phase measurements using directionally unbiased linear optics
David S. Simon, Christopher R. Schwarze, Alexander V. Sergienko
Grover multiports are higher-dimensional generalizations of beam splitters, in which input to any one of the four ports has equal probability of exiting at any of the same four por…
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…
