Deterministic positioning of circular Bragg gratings using atomic force lithography for high-performance quantum dot light sources
Sai Abhishikth Dhurjati, Moritz Langer, Yared G. Zena +6
Semiconductor quantum dots (QDs) grown by molecular beam epitaxy are excellent quantum emitters, but their random spatial distribution hinders deterministic coupling to optical mic…
Free-standing circular Bragg gratings enabling efficient GaAs quantum dot entangled photon pair sources
Sai Abhishikth Dhurjati, Moritz Langer, Yared G. Zena +6
Deterministic and bright quantum light sources based on scalable semiconductor technologies are a crucial building block for future quantum communication networks. While circular B…
Compact system development of efficient quantum-entangled photon sources towards deployable and industrial devices
Yared G. Zena, Moritz Langer, Ahmad Rahimi +9
Entangled photon pair sources are a key enabling technology for quantum communication and networking, yet their deployment beyond laboratory environments is hindered by system-leve…
Two-Qubit Implementation of QAOA for MAX-CUT on an NV-Center Quantum Processor
Leon E. Röscher, TalÃa L. M. Lezama, Luca Cimino +3
We report a proof-of-principle implementation of the quantum approximate optimization algorithm (QAOA) for the smallest nontrivial MAX-CUT instance on an NV-center-based quantum pr…
An ultra-compact deterministic source of maximally entangled photon pairs
M. Langer, P. Ruchka, A. Rahimi +9
We present an ultra-compact source of maximally entangled on-demand photon pairs. Our results are based on coupling of single GaAs quantum dots that are embedded in monolithic micr…
