Discrete frequency modes, or bins, present a blend of opportunities and challenges for
photonic quantum information processing. Frequency-bin-encoded photons are readily …

We present a second quantization description of frequency-based continuous variables
quantum computation in the subspace of single photons. For this, we define frequency and …

Many applications in optical quantum information processing benefit from careful spectral
sha** of single-photon wave-packets. In this paper we tailor the joint spectral wave …

High-dimensional entangled states of light provide novel possibilities for quantum
information, from fundamental tests of quantum mechanics to enhanced computation and …

Two-photon anti-bunching at a beamsplitter is only possible if the photons are entangled in
a specific state, anti-symmetric in the spatial modes. Thus, observation of anti-bunching is an …

Encoding information in the time–frequency domain demonstrates its potential for quantum
information processing. It offers a novel scheme for communications with large alphabets …

The propagation of several spatial modes has a significant impact on the structure of the
emission from parametric down-conversion in a nonlinear waveguide. This manifests itself …

We present experimental results on the generation of multi-spatial-mode, single-beam,
quadrature squeezed light using four-wave mixing in hot Rb vapor. Squeezing and phase …

Multimode squeezed light is an increasingly popular tool in photonic quantum technologies,
including sensing, imaging, and computation. Meanwhile, the existing methods of its …

Abstract The Hong-Ou-Mandel (HOM) experiment was a benchmark in quantum optics,
evidencing the non–classical nature of photon pairs, later generalized to quantum systems …
