An epsilon-near-zero-based nonlinear platform for ultrafast re-writable holography
M. Zahirul Alam, Robert Fickler, Yiyu Zhou +3
We re-examine real-time holography for all-optical structuring of light and optical computation using a contemporary material: a subwavelength-thick, spatially unstructured film of…
Experimental demonstration of superresolution of partially coherent light sources using parity sorting
S. A. Wadood, Kevin Liang, Yiyu Zhou +8
Analyses based on quantum metrology have shown that the ability to localize the positions of two incoherent point sources can be significantly enhanced through the use of mode sort…
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…
Turbulence-Resilient Coherent Free-Space Optical Communications using Automatic Power-Efficient Pilot-Assisted Optoelectronic Beam Mixing of Many Modes
Runzhou Zhang, Nanzhe Hu, Huibin Zhou +15
Atmospheric turbulence generally limits free-space optical (FSO) communications, and this problem is severely exacerbated when implementing highly sensitive and spectrally efficien…
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

The orbital angular momentum (OAM) of photons is a promising degree of freedom for high-dimensional quantum key distribution (QKD). However, effectively mitigating the adverse effe…
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…
Performance analysis of d-dimensional quantum cryptography under state-dependent diffraction
Jiapeng Zhao, Mohammad Mirhosseini, Boris Braverman +7
Standard protocols for quantum key distribution (QKD) require that the sender be able to transmit in two or more mutually unbiased bases. Here, we analyze the extent to which the p…
