Twist Engineering for Reconfigurable Optical and Optoelectronic Devices
Gang Huang, Annan Helian, Mengting Jiang +12
The paper reviews how rotating adjacent two‑dimensional layers or photonic lattices—known as twist engineering—enables compact, reconfigurable optical and optoelectronic devices by…
Ultimate sensitivity of multiparameter estimation in quantum sensing with undetected photons
Sanjeet Swaroop Panda, Lorcan O. Conlon, Li Gong +4
Quantum sensing with undetected photons is a technique where photons of one wavelength probe a sample, but information is extracted by measuring photons of another wavelength that…
In-Line Fiber-Integrated Photon-Pair Generation from van der Waals Crystals
Mayank Joshi, Tanumoy Pramanik, Mengting Jiang +9
Miniaturized quantum light sources that operate directly in optical fibers are an attractive platform for optical quantum technologies. However, most miniaturized spontaneous param…
Air-stable bright entangled photon-pair source from graphene-encapsulated van der Waals ferroelectric NbOI2
Mayank Joshi, Mengting Jiang, Yu Xing +6
Van der Waals (vdW) ferroelectrics are emerging nonlinear photonic materials that combine large second-order susceptibility \c{hi}(2) with heterostructure compatibility, offering a…
Precision Bounds for Characterising Quantum Measurements
Aritra Das, Simon K. Yung, Lorcan O. Conlon +6
Quantum measurements, alongside quantum states and processes, form a cornerstone of quantum information processing. However, unlike states and processes, their efficient characteri…
Saturating the Quantum Cramér--Rao Bound in Prioritised Parameter Estimation
Simon K. Yung, Aritra Das, Jun Suzuki +4
Measurement incompatibility is a cornerstone of quantum mechanics. In the context of estimating multiple parameters of a quantum system, this manifests as a fundamental trade-off b…
