Purcell enhanced and blinking free single photons from InAs/GaAs quantum dots in deterministically placed circular Bragg gratings
Peter Gschwandtner, Quirin Buchinger, Krishna Chand Maurya +11
The development of efficient, deterministic, and tunable single-photon sources is a cornerstone for the realization of long-distance quantum communication, quantum repeaters, and p…
Photonic Cluster State Generation from a Quantum Dot Emitting in the Telecom C-band
Giora Peniakov, Reza Hekmati, Johannes Michl +9
Photonic cluster states are a key resource for photonic quantum information processing. So far, deterministic generation of these states has been limited to the near-infrared wavel…
A Spin-Photon Interface in the Telecom C-Band with Long Hole Spin Dephasing Time
Johannes M. Michl, Reza Hekmati, Mohamed Helal +9
Matter qubits that maintain coherence over extended timescales are essential for many pursued applications in quantum communication and quantum computing. Significant progress has…
Deterministic Quantum Dot Cavity Placement Using Hyperspectral Imaging with High Spatial Accuracy and Precision
Quirin Buchinger, Constantin Krause, Aileen Zhang +6
Single emitters in solid state are great sources of single and entangled photons. To boost their extraction efficiency and tailor their emission properties, they are often incorpor…
Initialization of Neutral and Charged Exciton Spin States in a Telecom-Emitting Quantum Dot
Giora Peniakov, Johannes Michl, Mohamed Helal +6
Photonic cluster states are highly entangled states that allow for photonic quantum computing and memory-less quantum repeaters. Their generation has been recently demonstrated usi…
Polarized and Un-Polarized Emission from a Single Emitter in a Bullseye Resonator
Giora Peniakov, Quirin Buchinger, Mohamed Helal +12
We present polarized |S|=0.990.01, and unpolarized |S|=0.030.01 emission from a single emitter embedded in a single, cylindrically symmetric device design. We show that t…
Soft-clamped silicon nitride string resonators at millikelvin temperatures
Thomas Gisler, Mohamed Helal, Deividas Sabonis +5
We demonstrate that soft-clamped silicon nitride strings with large aspect ratio can be operated at \si{\milli\kelvin} temperatures. The quality factors () of two measured devic…
