18-dB on-chip vacuum squeezing in an adaptively poled lithium niobate waveguide
Tushar Sanjay Karnik, Xinyi Ren, Chun-Ho Lee +16
Quantum squeezed states of light can enhance measurement sensitivity beyond classical limits and enable quantum information processing, but scalable low-loss sources remain challen…
Breaking On/Off-coupling Loss Degeneracies via Bidirectional Nonlinear Optics
Bo-Han Wu, Mahmoud Jalali Mehrabad, Mengjie Yu +1
Accurate evaluation of nonlinear photonic integrated circuits requires separating input and output coupling efficiencies (i.e., and ), yet the conventional linear-tran…
Quantum squeezing in an all-resonant periodically poled lithium niobate microresonator
Xinyi Ren, Reshma Kopparapu, Tushar Sanjay Karnik +12
Quantum noise limits the sensitivity of optical measurements, but squeezed states of light enable quantum-enhanced metrology, sensing, and information processing. Most on-chip sque…
Programmable Quantum Photonic Interfaces for Quantum Networking
Siavash Mirzaei-Ghormish, Mahmoud Jalali Mehrabad, Helaman Flores +2
Quantum networks require interfaces translating memory photons to telecom wavelengths while controlling spatial modes; tasks performed by separate components today. We present a pr…
Broadband Spatio-Spectral Mode Conversion via Four-Wave Mixing
Helaman Flores, Mahmoud Jalali Mehrabad, Siavash Mirzaei-Ghormish +2
We introduce a framework for scalable and broadband free-space phase-matched four-wave mixing in ring resonators. This method for four-wave mixing reduces the complexity of couplin…
Quantum Metamorphosis: Programmable Emergence and the Breakdown of Bulk-Edge Dichotomy in Multiscale Systems
Mahmoud Jalali Mehrabad, Alireza Parhizkar, Lida Xu +6
Multiscale synergy -- the interplay of a system's distinct characteristic length, time, and energy scales -- is becoming a unifying thread across many contemporary branches of scie…
