Unveiling the Spin-Valley Structure of Dipolar Exciton Ladders in R-stacked WSe/WS Moiré Heterobilayers
Byeong Wook Cho, Tatyana V. Ivanova, Zhe Li +4
Localized interlayer excitons in moiré heterobilayers can form dipolar exciton ladders, yet their internal spin-valley structure remains unresolved. Here, we use helicity-resolved…
Photoexcitation of moiré-trapped interlayer excitons via chiral phonons
A. Borel, T. V. Ivanova, J. Cervantes-Villanueva +7
Moiré superlattices in transition-metal dichalcogenide semiconductor heterobilayers enable the quantum confinement of interlayer excitons with large out-of-plane permanent electri…
Roadmap: 2D Materials for Quantum Technologies
Qimin Yan, Tongcang Li, Xingyu Gao +29
Two-dimensional (2D) materials have emerged as a versatile and powerful platform for quantum technologies, offering atomic-scale control, strong quantum confinement, and seamless i…
Decoy-state quantum key distribution over 227 km with a frequency-converted telecom single-photon source
Frederik Brooke Barnes, Roberto G. Pousa, Christopher L. Morrison +7
We implement a decoy-state quantum key distribution scheme using a telecom C-band single-emitter source. The decoy states are created by varying the optical excitation of the quant…
Highly tunable band structure in ferroelectric R-stacked bilayer WSe
Zhe Li, Prokhor Thor, George Kourmoulakis +6
Transition metal dichalcogenide homobilayers unite two frontiers of quantum materials research: sliding ferroelectricity, arising from rhombohedral (R) stacking, and moiré quantum…
Broadband Fourier transform spectroscopy of quantum emitters photoluminescence with sub-nanosecond temporal resolution
Issam Belgacem, Pasquale Cilibrizzi, Muhammad Junaid Arshad +15
The spectral characterization of quantum emitter luminescence over broad wavelength ranges and fast timescales is important for applications ranging from biophysics to quantum tech…
