Integrated external cavity lasers will enhance quantum atomic technologies
Photonic integrated circuits could reduce laser systems to chip-scale devices. Cold atoms provide a powerful platform for the implementation of technological applications in quantum computing, sensing and communication. Electronic transitions in these atoms have very precise and particular wavelengths. Lasers that can be tuned to these exact wavelengths are required to manipulate the internal […]

Entangled Photon Orbital Angular Momentum Arrays
Summary Arrays of orbital angular momentum (OAM) states of light are a new form of structured light so far relatively unexplored in quantum information science. Unlike spin angular momentum of light, which is related to light’s polarization and covers two dimensions, OAM states, sometimes described as ‘donut beams’ due to the shape of the field […]
