To bring quantum technologies to market takes both technical expertise and commercial acumen. We combine skills with industry partners to maximise the chances of success and impact. This page highlights projects and partnerships initiated or led by CQT Principal Investigators and research staff.
Supported by Singapore’s DSO National Laboratories, CQT Principal Investigators began in 2020 applied research projects: “Research Collaboration On Optical Ground Station For Satellite Quantum Communications” led by Alexander Ling, and “Assessment On Advanced Inertial Sensing Techniques For Navigation And Characterization Of An Atomic Gravimeter Platform” led by Rainer Dumke.
SGInnovate is a Singapore government-backed organisation supporting the local development of deep tech. They have a partnership with CQT to support quantum as one of their focus areas, involving talks, training and support for startups.

Title: Optimizing All-fiber Broadband Nonlocal Dispersion Compensation for Quantum Communication Networks Date/Time: 24-May, 02:00PM Venue: Online via Zoom
Abstract: Spontaneous Parametric Down Converted photon pairs possesses a high degree of temporal correlation. While fiber-based quantum communication networks threaten to degrade these correlations via chromatic dispersion, they can simultaneously serve as a solution to its own problem via Nonlocal Dispersion Compensation. This phenomenon can take into effect when the SPDC source is designed to have its paired photons experience opposite chromatic dispersion coefficients when propagated through the telecommunication fiber, enabling their energy anti-correlation property to minimize the variance in the possible delays between them, and thereby reducing or even nullify the effect of chromatic dispersion on the overall timing correlation. At this juncture, this solution has been shown to be effective in nearly eliminating chromatic dispersion completely across the full, broadband, SPDC spectrum when propagated over 40km of telecommunication fiber with a projected loss of no more than 0.8dB. Some strategies were implemented to optimize the efficacy of this solution, which is the topic of discussion.
