BBOI results again in Nature Communications

Photonics at the surface of silicon waveguides  
The BBOI team from the Politecnico di Milano has unveiled that light propagation through a silicon photonic waveguide creates an extremely thin (a few atoms) highly-conductive surface sheet, which significantly modifies the optical and electrical properties of the waveguide itself.
This effect is extremely fast and efficient, and may be exploited to realize new device concepts based on surface effects, such as ultrafast optical detectors and ultra-low energy optical transmitters.

Universal linear optics  
The BBOI team from the Centre for Quantum Photonics of the University of Bristol has demonstrated a single reprogrammable integrated optical circuit that can implement all possible linear optical protocols up to the size of that circuit.
A six-mode universal system has been realized that integrates 15 Mach-Zehnder interferometers controlled though 30 thermo-optic phase actuators.
This system is programmed to implement heralded quantum logic and entangling gates, boson sampling with verification tests, and six-dimensional complex Hadamards.

Qubit entanglement between ring-resonator photon-pair sources on a silicon chip   
The BBOI teams from the Centre for Quantum Photonics of the University of Bristol and from the University of Glasgow have demonstr
ated a silicon photonic chip that uses resonant-enhanced photon-pair sources, spectral demultiplexers and reconfigurable optics to generate a path-entangled two-qubit state.
Quantum state tomography and the strict Bell-CHSH test are performed that confirm a high level of on-chip entanglement.
This work demonstrates the integration of high-performance components for quantum integrated devices and systems to harness photonic entanglement on the large scale.
