Generation and detection of squeezed light on a single silicon photonic chip
Oliver M. Green, Bethany Puzio, Rowan A. Hoggarth +5
The ability to generate and detect quantum states of light on a single integrated photonic device is essential to scale quantum photonics into useful quantum technologies. Integrat…
Deploying and validating a metropolitan QKD secure network: architecture and field performance
Claudia De Lazzari, Nicola Biagi, Damiano Giani +15
The advent of cryptographically relevant quantum computers poses an existential threat to classical public-key infrastructure. Quantum Key Distribution (QKD) addresses this challen…
9~GHz measurement of squeezed light by interfacing silicon photonics and integrated electronics
Joel F. Tasker, Jonathan Frazer, Giacomo Ferranti +5
Photonic quantum technology can be enhanced by monolithic fabrication of both the underpinning quantum hardware and the corresponding electronics for classical readout and control.…
Passive, broadband and low-frequency suppression of laser amplitude noise to the shot-noise limit using hollow-core fibre
Euan J. Allen, Giacomo Ferranti, Kristina R. Rusimova +6
We use hollow-core fibre to preserve the spectrum and temporal profile of picosecond laser pulses in CBD to suppress 2.6 dB of amplitude noise at MHz noise frequencies, to within 0…
