Isolation of Single Donors in ZnO
Ethan R. Hansen, Vasileios Niaouris, Bethany E. Matthews +6
The shallow donor in zinc oxide (ZnO) is a promising semiconductor spin qubit with optical access. Single indium donors are isolated in a commercial ZnO substrate using plasma focu…
Contributions to the optical linewidth of shallow donor-bound excitonic transition in ZnO
Vasileios Niaouris, Samuel H. D'Ambrosia, Christian Zimmermann +5
Neutral shallow donors in zinc oxide (ZnO) are spin qubits with optical access via the donor-bound exciton. This spin-photon interface enables applications in quantum networking, m…
Properties of donor qubits in ZnO formed by indium ion implantation
Xingyi Wang, Christian Zimmermann, Michael Titze +6
Shallow neutral donors (D) in ZnO have emerged as a promising candidate for solid-state spin qubits. Here, we report on the formation of D in ZnO via implantation of In…
Ensemble spin relaxation of shallow donor qubits in ZnO
Vasileios Niaouris, Mikhail V. Durnev, Xiayu Linpeng +6
We present an experimental and theoretical study of the longitudinal electron spin relaxation () of shallow donors in the direct band-gap semiconductor ZnO. is measured…
Coherent Spin Preparation of Indium Donor Qubits in Single ZnO Nanowires
Maria L. K. Viitaniemi, Christian Zimmermann, Vasileios Niaouris +6
Shallow donors in ZnO are promising candidates for photon-mediated quantum technologies. Utilizing the indium donor, we show that favorable donor-bound exciton optical and electron…
Photon-mediated entanglement scheme between a ZnO semiconductor defect and a trapped Yb ion
Jennifer F. Lilieholm, Vasilis Niaouris, Alexander Kato +2
We propose an optical scheme to generate an entangled state between a trapped ion and a solid state donor qubit through which-path erasure of identical photons emitted from the two…
Timing Performance of a Micro-Channel-Plate Photomultiplier Tube
Jonathan Bortfeldt, Florian Brunbauer, Claude David +36
The spatial dependence of the timing performance of the R3809U-50 Micro-Channel-Plate PMT (MCP-PMT) by Hamamatsu was studied in high energy muon beams. Particle position informatio…
