Research Description
Alireza Marandi’s research aims to open a new regime of quantum information processing by asking whether quantum states can be created, measured and used within a single cycle of light. His team is developing integrated photonic circuits in lithium niobate that can generate and control ultrashort optical pulses on femtosecond timescales. The work combines optical amplifiers, oscillators, pulse shaping and ultrafast measurement methods to probe quantum behavior in nanophotonic circuits operating at extremely fast time scales.
Research Impact
Marandi’s work could help define how quantum information behaves when it is confined to exceptionally short time scales and broad optical bandwidths. If successful, the project could establish an experimental foundation for faster and more compact photonic technologies, while clarifying the limits of integrated quantum optics in regimes that existing systems do not reach. The results could inform future approaches to quantum sensing, communication and information processing.
