Universal N-Partite d-Level Pure-State Entanglement Witness Based on Realistic Measurement Settings

  Prof. Morandotti’s group demonstrates a universal entanglement witness operators capable of detecting any pure quantum state with feasible measurement. Entanglement is an essential resource in quantum information science and its presence in any quantum system can be experimentally detected through entanglement witness operators. In …

High-dimensional one-way quantum processing implemented on d-level cluster states

  Prof. Morandotti’s group demonstrates a multipartite d-level two-photon cluster state in the time and frequency domains. Quantum information science focuses on the realization of large-scale complex quantum systems to enable, e.g., ultra-secure communications and computations faster than classical approaches. In this context, ‘cluster states’, …

Scaling On-Chip Entangled Photon States to Higher Dimensions

  To reach the processing capabilities required for meaningful quantum information science it is necessary to scale up information content that we can handle. To this end, considerable efforts were devoted to increasing the number of qubits (the simplest unit of quantum information) in nonclassical systems …

Passively mode-locked laser with an ultra-narrow spectral width

Prof. Morandotti’s group demonstrates a technique for generating a stable coherent train of ultra-short laser pulses. Most mode-locking techniques introduced in the past focused mainly on increasing the spectral bandwidth to achieve ultrashort, sub-picosecond-long coherent light pulses. By contrast, less importance seemed to be given …

Real-time measurements of spontaneous breathers and rogue wave events in optical fibre modulation instability

Prof. John Dudley, in collaborations with Prof. Morandotti’s team develop a new approach to study mechanical instabilties of ondulatory motion. Modulation instability is a fundamental process of nonlinear science, leading to the unstable breakup of a constant amplitude solution of a physical system. There has …
