The production of pairs of entangled photons simply by focusing a laser beam onto a crystal
with a nonlinear optical response was used to test quantum mechanics and to open new …

Entanglement is a quintessential quantum mechanical phenomenon with no classical
equivalent. First discussed by Einstein, Podolsky, and Rosen and formally introduced by …

Low-light-level imaging techniques have application in many diverse fields, ranging from
biological sciences to security. A high-quality digital camera based on a multi-megapixel …

Single-pixel imaging (SPI) is a novel technique that captures 2D images using a photodiode,
instead of conventional 2D array sensors. SPI has high signal-to-noise ratio, wide spectral …

Even though ghost imaging (GI), an unconventional imaging method, has received
increased attention by researchers during the last decades, imaging speed is still not …

Existing multispectral imagers mostly use available array sensors to separately measure 2D
data slices in a 3D spatial-spectral data cube. Thus they suffer from low photon efficiency …

We demonstrate a compressed sensing, photon counting lidar system based on the single-
pixel camera. Our technique recovers both depth and intensity maps from a single under …

Conventional imaging systems rely upon illumination light that is scattered or transmitted by
the object and subsequently imaged. Ghost-imaging systems based on parametric down …

Real-time tracking of fast-moving object have many important applications in various fields.
However, it is a great challenge to track of fast-moving object with high frame rate in real …

The maturity of fields such as optical physics and quantum optics has brought with it a new
era where the photon represents a promising information resource. In the past few years …
