Direct tomography of high-dimensional density matrices for general quantum states of photons
Yiyu Zhou, Jiapeng Zhao, Darrick Hay +3
Quantum state tomography is the conventional method used to characterize density matrices for general quantum states. However, the data acquisition time generally scales linearly w…
Confocal super-resolution microscopy based on a spatial mode sorter
Katherine K. M. Bearne, Yiyu Zhou, Boris Braverman +6
Spatial resolution is one of the most important specifications of an imaging system. Recent results in quantum parameter estimation theory reveal that an arbitrarily small distance…
Multiprobe time reversal for high-fidelity vortex-mode-division multiplexing over a turbulent free-space link
Yiyu Zhou, Jiapeng Zhao, Boris Braverman +5
The orbital angular momentum (OAM) of photons presents a degree of freedom for enhancing the secure key rate of free-space quantum key distribution (QKD) through mode-division mult…
High-fidelity spatial mode transmission through a 1-km-long multimode fiber via vectorial time reversal
Yiyu Zhou, Boris Braverman, Alexander Fyffe +5
The large number of spatial modes supported by standard multimode fibers is a promising platform for boosting the channel capacity of quantum and classical communications by orders…
Compensation-Free High-Capacity Free-Space Optical Communication Using Turbulence-Resilient Vector Beams
Ziyi Zhu, Molly Janasik, Alexander Fyffe +7
Free-space optical communication is a promising means to establish versatile, secure and high-bandwidth communication for many critical point-to-point applications. While the spati…
Quantum-limited estimation of the axial separation of two incoherent point sources
Yiyu Zhou, Jing Yang, Jeremy D. Hassett +6
Improving axial resolution is crucial for three-dimensional optical imaging systems. Here we present a scheme of axial superresolution for two incoherent point sources based on spa…
Hermite-Gaussian mode sorter
Yiyu Zhou, Jiapeng Zhao, Zhimin Shi +5
The Hermite-Gaussian (HG) modes, sometimes also referred to as transverse electromagnetic modes in free space, form a complete and orthonormal basis that have been extensively used…
Realization of a scalable Laguerre-Gaussian mode sorter based on a robust radial mode sorter
Dongzhi Fu, Yiyu Zhou, Rui Qi +8
The transverse structure of light is recognized as a resource that can be used to encode information onto photons and has been shown to be useful to enhance communication capacity…
On-chip spectroscopy with thermally-tuned high-Q photonic crystal cavities
Andreas C. Liapis, Boshen Gao, Mahmudur R. Siddiqui +2
Spectroscopic methods are a sensitive way to determine the chemical composition of potentially hazardous materials. Here, we demonstrate that thermally-tuned high-Q photonic crysta…
Direct measurement of a one-million-dimensional photonic state
Zhimin Shi, Mohammad Mirhosseini, Jessica Margiewicz +3
Retrieving the vast amount of information carried by a photon is an enduring challenge in quantum metrology science and quantum photonics research. The transverse spatial state of…
Efficient separation of the orbital angular momentum eigenstates of light
Mohammad Mirhosseini, Mehul Malik, Zhimin Shi +1
Orbital angular momentum (OAM) of light is an attractive degree of freedom for funda- mentals studies in quantum mechanics. In addition, the discrete unbounded state-space of OAM h…
Electromagnetic Momentum in Dispersive Dielectric Media
Douglas H. Bradshaw, Zhimin Shi, Robert W. Boyd +1
When the effects of dispersion are included, neither the Abraham nor the Minkowski expression for electromagnetic momentum in a dielectric medium gives the correct recoil momentum…
