The investigation of integrated frequency comb sources characterized by equidistant spectral modes was initially driven considerations toward classical applications, seeking a more practical and miniaturized way to generate stable broadband light. Recently, in the context scaling complexity optical quantum circuits, these on-chip approaches have provided new framework address challenges associated with non-classical state generation manipulation. For example, multi-photon high-dimensional...
Abstract Well‐controlled yet practical systems that give access to interference effects are critical for established and new functionalities in ultrafast signal processing, quantum photonics, optical coherence characterization, etc. Optical fiber constitute a central platform such technologies. However, harnessing versatile stable manner remains technologically costly challenging. Here, degrees of freedom native fibers, i.e., polarization frequency, used demonstrate an easily deployable...

We have presented the optimized Lorentz model parameters for crystalline arsenic sulfide (AS2S3), silicon carbide (SiC) and modified nanocrystalline monoxide (SiO) obtained using a large scale non-linear algorithm. The complex relative permittivity calculated agree well with experimental values over broad frequency bands. associated RMS deviations are 0.254, 0.003, 0.010 0.009 respectively.
Abstract:Cross-phase modulation (XPM) changes the state-of-polarization (SOP) of channelsthrough nonlinear polarization rotation and induces time dependent phaseshift for components that leads to amplitude propagatingwaves in a wavelength division multiplexing (WDM) system. Due presence ofbirefringence, angle between SOP randomly as result polarizationmode dispersion (PMD) causes XPM fluctuation random theperturbed channel. In this paper we analytically determine probability densityfunction...
We present the compact and scalable realization of four-photon time-bin entangled states using a quantum frequency comb generated from an integrated photonic chip. show how noise affects higher-order spontaneous emissions for this state.
Integrated frequency combs introduce a scalable framework for the generation and manipulation of complex quantum states (including multi-photon high-dimensional states), using only standard silicon chip fiber telecommunications components.
We implement on-chip generation of high-dimensional hyper-entangled states in the time-and frequency-domain, and transform them into d-level cluster using a deterministic controlled phase gate. then demonstrate measurement-based quantum computing operations show state's high tolerance towards noise. © 2019 The Author(s)
We demonstrate the on-chip generation of time-bin entangled two- and multi-photon qubit states, as well high-dimensional frequency-entangled photon pairs. Combining time frequency entanglement, we generate optical cluster states implement proof-of-concept one-way quantum computing. This, by using standard, fiber-based telecommunication components.
Large and complex optical quantum states are a key resource for fundamental science applications such as communications, information processing, metrology. In this context, cluster particularly important class because they enable the realization of universal computers by means so-called `one-way' scheme, where processing operations performed through measurements on state. While two-level (i.e. qubit) have been realized thus far, further boosting computational increasing number particles...
Hyper-entanglement, i.e. entanglement in more than one degree of freedom, enables a multiplicative increase Hilbert space size. Such systems can be treated as multi-partite even though the number state particles is not increased, making them highly attractive for applications high-capacity quantum communications and information processing [1]. Until now, such states have been realized only using combinations fully independent degrees described by commuting operators, polarization optical...
Cluster states, a specific class of multi-partite entangled are particular importance for quantum science, as such systems equivalent to the realization one-way (or measurement-based) computers [1]. In this scheme, algorithms implemented through high-fidelity measurements on parties state [2]. While two-level (i.e. qubit) cluster states have been realized so far, increasing number particles boost computational resource comes at price significantly reduced coherence time and detection rates,...
Time is a practical and robust degree of freedom for the encoding quantum information. Qubits encoded in so-called `time-bins', allowing discrete superposition two potential arrival times, have their entanglement preserved even over long propagation distances standard fiber networks [1]. has also been used preparation more complex systems, such as hyper-entangled cluster states [2]. These qualities put time-bin at center applications ranging from state through to communications information...

A key challenge in today's quantum science is the realization of large-scale complex non-classical systems to enable e.g. ultra-secure communications, quantum-enhanced measurements, and computations faster than classical approaches. Optical frequency combs represent a powerful approach towards this, since they provide very high number temporal modes which can result systems. Here, we discuss recent progress on integrated reveal how their use combination with on-chip fiber-optic...

Quantum frequency combs (QFCs) generated via spontaneous four-wave mixing in integrated microring resonators represent a powerful tool towards this goal. They enable generation photon states within single spatial mode as well their manipulation using standard fiber-based telecommunication...
