Distributed Quantum Computing in Silicon
Photonic Inc, :, Francis Afzal +69
Commercially impactful quantum algorithms such as quantum chemistry and Shor's algorithm require a number of qubits and gates far beyond the capacity of any existing quantum proces…
Helicity-selective Raman scattering from in-plane anisotropic α-MoO
Shahzad Akhtar Ali, Abdullah Irfan, Aishani Mazumder +4
Hyperbolic crystals like α-MoO can support large wavevectors and photon density as compared to the commonly used dielectric crystals, which makes them a highly desirable platfo…
Measurement of the spin temperature of optically cooled nuclei and GaAs hyperfine constants in GaAs/AlGaAs quantum dots
E. A. Chekhovich, A. Ulhaq, E. Zallo +3
Deep cooling of electron and nuclear spins is equivalent to achieving polarization degrees close to 100% and is a key requirement in solid state quantum information technologies. W…
Electron and nuclear spin properties of the nanohole-filled GaAs/AlGaAs quantum dots
Ata Ulhaq, Qingqing Duan, Fei Ding +5
GaAs/AlGaAs quantum dots grown by in-situ droplet etching and nanohole infilling offer a combination of strong charge confinement, optical efficiency, and spatial symmetry required…
Mollow "quintuplets" from coherently-excited quantum dots
Rong-Chun Ge, S. Weiler, A. Ulhaq +4
Charge-neutral excitons in semiconductor quantum dots have a small finite energy separation caused by the anisotropic exchange splitting. Coherent excitation of neutral excitons wi…
Detuning-Dependent Mollow Triplet of a Coherently-Driven Single Quantum Dot
Ata Ulhaq, Stefanie Weiler, Chiranjeeb Roy +4
We present both experimental and theoretical investigations of a laser-driven quantum dot (QD) in the dressed-state regime of resonance fluorescence. We explore the role of phonon…
Phonon-Assisted Incoherent Excitation of a Quantum Dot and its Emission Properties
S. Weiler, A. Ulhaq, C. Roy +5
We present a detailed study of a phonon-assisted incoherent excitation mechanism of single quantum dots. A spectrally-detuned laser couples to a quantum dot transition by mediation…
Heralded Single-Photon Emission from the Mollow Triplet Sidebands of a Quantum Dot
Ata Ulhaq, Stefanie Weiler, Sven M. Ulrich +3
Emission from a resonantly excited quantum emitter is a fascinating research topic within quantum optics and a useful source for different types of quantum light fields. The resona…
Non-resonant dot-cavity coupling and its applications in resonant quantum dot spectroscopy
S. Ates, S. M. Ulrich, A. Ulhaq +5
We present experimental investigations on the non-resonant dot-cavity coupling of a single quantum dot inside a micro-pillar where the dot has been resonantly excited in the s-shel…
{\it In-situ} Laser Microprocessing at the Quantum Level
Armando Rastelli, Ata Ulhaq, Suwit Kiravittaya +3
One of the biggest challenges of nanotechnology is the fabrication of nano-objects with perfectly controlled properties. Here we employ a focused laser beam both to characterize an…
