Boson Sampling is a computational paradigm representing one of the most viable and pursued approaches to demonstrate regime quantum advantage. Recent results have demonstrated significant technological leaps in single-photon generation detection, leading progressively larger experimental instances experiments different photonic systems. However, crucial requirement for fully-fledged platform solving this problem capability implementing large-scale interferometers, that must simultaneously...
Abstract Quantum walks represent paradigmatic quantum evolutions, enabling powerful applications in the context of topological physics and computation. They have been implemented diverse photonic architectures, but realization two-particle dynamics on a multidimensional lattice has hitherto limited to continuous-time evolutions. To fully exploit computational capabilities interference it is crucial develop platforms handling multiple photons that propagate across lattices. Here, we report...
Quantum superposition of high-dimensional states enables both computational speed-up and security in cryptographic protocols. However, the exponential complexity tomographic processes makes certification these properties a challenging task. In this work, we experimentally certify coherence witnesses tailored for quantum systems increasing dimension using pairwise overlap measurements enabled by six-mode universal photonic processor fabricated with femtosecond laser writing technology....
Quantum walks are powerful tools for quantum applications and designing topological systems. Although they simulated in a variety of platforms, genuine two-dimensional realizations still challenging. Here we present an innovative approach to the photonic simulation walk two dimensions, where walker positions encoded transverse wavevector components single light beam. The desired dynamics is obtained by means sequence liquid-crystal devices, which apply polarization-dependent "kicks" photons...
Photon indistinguishability plays a fundamental role in information processing, with applications such as linear-optical quantum computation and metrology. It is then necessary to develop appropriate tools quantify the amount of this resource multiparticle scenario. Here we report four-photon experiment interferometer designed simultaneously estimate degree between three pairs photons. The design dispenses need heralding for parametric down-conversion sources, resulting an efficient reliable...
Tankyrases (TNKSs) have recently gained great consideration as potential targets in Wnt/β-catenin pathway-dependent solid tumors. Previously, we reported the 2-mercaptoquinazolin-4-one MC2050 a micromolar PARP1 inhibitor. Here show how resolution of X-ray structure complex with MC2050, combined computational investigation structural differences between TNKSs and PARP1/2 active sites, provided rationale for structure-based drug design campaign that limited synthetic effort led to discovery...
Quantum coherence marks a deviation from classical physics, and has been studied as resource for metrology quantum computation. Finding reliable effective methods assessing its presence is then highly desirable. Coherence witnesses rely on measuring observables whose outcomes can guarantee that state not diagonal in known reference basis. Here we experimentally measure novel type of witness uses pairwise comparisons to identify superpositions basis-independent way. Our experiment single...
Several quantum protocols, with applications ranging from fundamental studies to cryptographic scenarios, can be enhanced through the generation and manipulation of states that belong high-dimensional Hilbert spaces. For this reason, it is worth devoting efforts find more efficient methods for complex qudit-state generation. One-dimensional walks have proved versatile platforms engineering such states. Hitherto, however, using their two-dimensional counterpart task has remained unexplored....
We mimic one dimensional forced quantum walks by using the photonic implementation obtained means of a sequence liquid-crystal devices ("g-plates"), which apply polarization-dependent transverse kicks to photons in beam. observed refocusing phenomena for localized initial states.
A new photonic platform allows implementing 2D Quantum Walks in the space of transverse wavevector components a single light beam. Detection an anomalous velocity demonstrates that this system simulates Hall Insulator.
