SPIN Code of Conduct
To better support diversity, equity, and inclusion of its community, SPIN decided to adopt a Code of Conduct, installed by the SPIN Executive Committee. To foster a culture based on integrity, trust and inclusion, this Code of Conduct applies to all the SPIN members.
Here below, you can find the text of the SPIN Code of Conduct.
----------------------------------------------------------------------------------------------------------------------------------------------------------------------
A core principle of the mission, vision, and values of NCCR SPIN is creating a physics community that fosters diversity, equity, and inclusion; A diversity of views, backgrounds, and opinions supports scientific creativity and productivity. Therefore, creating a climate that encourages growth and facilitates the inclusion of everyone associated with our SPIN network’s activities is a high priority.
To create a collegial, inclusive, and professional environment, SPIN network members will treat each other with respect and consideration.
SPIN network members will avoid any inappropriate actions or statements based on individual characteristics such as age, race, ethnicity, sexual orientation, gender identity, gender expression, marital status, nationality, political affiliation, ability status, religion or educational background or any other characteristic protected by law.
Disruptive or harassing behavior of any kind will not be tolerated. Harassment includes but is not limited to inappropriate or intimidating behavior and language (and body language), unwelcome jokes or comments, unwanted touching or attention, bullying, offensive images, and stalking.
This Code of Conduct shall be a supplement to the Codes of Conduct of the institutions in the SPIN network.
Violations of this code of conduct policy should be reported to one of the members of the board of the NCCR SPIN Directors listed below:

A hole spin qubit in a field-effect transistor above 4 kelvin
The greatest challenge in quantum computing is achieving scalability. Classical computing, which previously faced such issues, currently relies on silicon chips hosting billions of fin field-effect transistors. These devices are small enough for quantum applications: at low temperatures, an electron or hole trapped under the gate can serve as a spin qubit. Such an approach potentially allows the quantum hardware and its classical control electronics to be integrated on the same chip. However, this requires qubit operation at temperatures above 1 K, where the cooling overcomes heat dissipation.
Researchers of the University of Basel as well as IBM Research Zurich – namely Leon C. Camenzind, Simon Geyer, Andreas Fuhrer, Richard J. Warburton, Dominik M. Zumbühl, and Andreas V. Kuhlmann –have shown that silicon fin field-effect transistors can host spin qubits operating above 4 K. They achieved fast electrical control of hole spins with driving frequencies up to 150 MHz, single-qubit gate fidelities at the fault-tolerance threshold and a Rabi-oscillation quality factor greater than 87. The paper was published in Nature Electronics.

Scientific Advisory Board
In 2022, SPIN established a Scientific Advisory Board (SAB). The role of the SAB is to provide advice and suggestions on scientific development in the field of spin qubits and participate in the SPIN events. You can find a short profile of the SAB members here below.

David Divincenzo
David received his doctorate at the University of Pennsylvania, Philadelphia, USA in 1983; was a postdoc at Cornell University, Ithaca, USA; then Research Staff Member at IBM Watson Research Center, Yorktown Heights, New York, USA (1985-2011). In 2010, he became a professor at the Institute of Theoretical Quantum Information at RWTH Aachen University and director of the Peter Grünberg Institute, where he serves to the present. David DiVincenzo was one of the first physicists to engage in quantum information research and his name is associated with the development of criteria for the quantum computer.

News from the Annual Meeting 2022
The second SPIN Annual Meeting was held in June 2022 in Pontresina. More than a hundred SPIN members gathered to share their recent scientific advancements, discuss future directions and enjoy the wonderful landscape in Engadin valley.
The SPIN Young Researchers (YR) Assembly was an important opportunity for community building and networking for PhD students and postdocs. The assembly also decided on the potential dates and venues for the YR retreat and school. The retreat will be held tentatively in Fall 22/23 in Engelberg and the school in Spietz in Spring 2023. Moreover, YR were also awarded Excellent Paper and Best Image and Poster Flash-intro awards at the meeting.
SPIN welcomed the members of the Scientific Advisory Board (SAB) members participating for the first time at the SPIN Annual Meeting.

Excellent paper, image contest and poster flash awards
Excellent paper award
For the first time, the NCCR SPIN recognizes outstanding papers written by Youn Researchers as a first author with an award.
Here is the list of awardees.
Stefano Bosco (Unibas)
-
Paper: Hole spin qubits in Si FinFETs with fully tunable spin-orbit coupling and sweet spots for charge noise PRX Quantum (2021)
-
Motivation: This is a very substantial and important piece of work identifying sweet spots for low noise and optimal control, which has already attracted a lot of attention in the community, as also evidenced by the rapidly increasing citations. This work will significantly impact the further development of spin qubits based on holes in Si and Ge, the central theme of the NCCR Spin.

-
Paper: A hole spin qubit in a fin field-effect transistor above 4 kelvin Nature Electronics (2022)
-
Motivation: This is break-through work, published in Nature Electronics in March 2022: the finFET hole spins work up above 4.2 Kelvin, where very large cooling power becomes available, thus making integration of the qubit control electronics possible. Further, the finFET hole spins are already very coherent and easy to manipulate, achieving ~99% fidelity. Finally, the finFET approach gives extremely high-quality devices ("industry quality"), yet are fabricated in a flexible and fast-turn-around process, which is very helpful for further development.

Paper: Coherent Hole Transport in Selective Area Grown Ge Nanowire Networks Nanoletters (2021)
-
Motivation: This paper demonstrates for the first-time coherent hole transport in Ge nanowires and networks obtained by the selective area method, which is intrinsically scalable. The shape of the nanowires with triangular caps would enable the manipulation of SOI to cancel hyperfine interaction. This work was created thanks to the existence of the NCCR and has been successful thanks to the tight collaboration between the two PhD students, who have interacted on a nearly daily basis, exchanging many devices and grown wafers as expertise. It is a clear example of what an NCCR should achieve.
