Entanglement-controlled vectorial meta-holography

Sheng Ye, Yue Han, Li-Zheng Liu +7 more

Metasurfaces can precisely manipulate the amplitude, phase, and polarization of incident light through subwavelength structures, greatly advancing the quantum meta-holographic imaging. However, the current methods of using quantum holography only control either the amplitude or the phase on the imaging plane, so the resulted scalar holography without the polarization distribution has limited imaging channels. Here, the vectorial meta-holography using entangled signal-idler photon pairs is experimentally demonstrated to realize remotely controlled multi-channel quantum imaging. By simultaneous control of the amplitude ratio between two cross-polarization holographic images and their phase difference on the image plane, the polarization distribution accordingly changes with the incident polarization state. The accurate correspondence ensures the correct reconstruction of 32 incident polarization states with an average fidelity up to 94.78%. This enables entangled idler photons to remotely control the holographic images reconstructed by the entangled signal photons, where the signal-to-noise ratio is as high as 10.78 dB, even for maximally mixed quantum states. This vectorial meta-holography using entangled states has a larger polarization state information capacity and will facilitate miniaturized quantum imaging and efficient quantum state tomography.

Quantum Nonlocal Holography via Multichannel Metasurfaces

Q H Li, Minggui Liang, Shuangchun Wen +1 more

Holography provides comprehensive characterization of complex light fields, laying the foundation for biological microscopy and precision measurement. Although the amplitude and phase information can be quantitatively analyzed through phase-shifting holography, the additional beam deflection during multistep phase-shifting operations and the shot noise will inevitably reduce the accuracy of holography. Here, a quantum nonlocal holography via multichannel metasurfaces (QNHM) is proposed to achieve high-quality holography under high noise levels. By integrating multiple quantum channels on the metasurface, the projection probabilities of idler photons in four polarization bases are simultaneously measured. Since the spatiotemporal field of signal photons are nonlocally modulated by the polarization of idler photons, the phase-shifting operations is completely avoided. The coincidence measurement greatly filters out the shot noise from the time domain, thereby enhancing the signal-to-noise ratio, image contrast, and accuracy. The proposed QNHM may open up feasible avenues in biomedicine, material analysis, and quantum information processing.

On-chip metasurface strategies for versatile and structured quantum light emission

Shailesh Kumar

Manipulating photoluminescence from solid-state quantum emitters (QEs) on demand is of central importance for advanced quantum nanophotonic technologies. In comparison with conventional free-space approaches relying on bulky optical components, emitter-integrated metasurfaces provide a compact and efficient route for shaping photon emission directly at the source. Recent progress has established a common platform in which QE-excited surface plasmon polaritons (SPPs) are transformed by surrounding metasurfaces into free-space radiation with tailored propagation direction, polarization state, relative intensity, and spatial structure. This review highlights two complementary strategies that have recently been utilized for shaping quantum emission. The first is emitter-coupled meta-optics, which enables versatile photon sources with arbitrary polarization states, off-normal directionality, and multichannel emission by means of phase-engineered anisotropic meta-atoms. The second is vectorial scattering holography, including multiplexed implementations, which allows direct reconstruction of arbitrarily structured and polarization-multiplexed emission from individual nanodiamonds. Together, these approaches unlock unprecedented degrees of freedom for nanoscale light shaping and provide a promising route toward scalable quantum photonic devices and high-capacity information processing.
