Quantum Computing Files will be starting back
Something intersting to share on Quantum Computing.
Hello! Quite some time without writing anything in this publication. But Quantum Computing Files is back now with a number 2 post. Let us now start back with some posts on interesting developments in Quantum Computing! We will be striving to be creative as well.
Qiskit is a major Quantum Computing project coming out of multinational technology company IBM. It is an open-source software platform for developers, engineers and just about anyone who wants to learn by doing Quantum Computing. Naturally in this blog/newsletter there will be often shared materials from Qiskit. I will assume potential target audience/s of this publication will be already familiar with the basics of Quantum Computing. Then we can go on and publish some more involved/advanced content. That is the case with the two links Quantum Computing Files is sharing here today. The first is a Blog post at Medium, from Qiskit Blog, about a current developments in Germany, with this major European country doing some bold announcements about how it plans to invest significantly in Quantum Technologies in the years ahead.
The second resource we are providing today comes also from Qiskit, but in this case is a video on its YouTube channel, featuring another recent Qiskit Seminar Series video with usual insighful science and research with a particular research invoving Quantum Computing, Qubits, Quantum Instrumentation and all Quantum Physics/Chemistry related issues! I recommend everyone to check the full list of these published videos in this Seminar Series, with some really good insightful ones anyone can find and re-watch!

How Germany is Building a Quantum Computing Ecosystem (Qiskit Blog - June 15th)
By Ryan F. Mandelbaum, Sieglinde Pfaendler, and Fabio Scafirimuto
This year, Germany kicked off its Roadmap Quantencomputing to lay the groundwork for a German-based quantum computing ecosystem. The country has earmarked two billion euros in order to see the vision through. But building a quantum computing landscape is about more than just hardware; it requires collaboration between research institutions, industry, government, and most importantly, the community.
The IBM Quantum Researchers program instead focuses on academic researchers, including postdoctoral researchers and Ph.D students, working on quantum computing research projects that could potentially lead to impactful publications in areas such as the development of new algorithms or improved control of qubit systems. Currently, there are various 5- and 7-qubit systems available for academics enrolled in this program. Additionally, for researchers requiring more advanced systems for their work, IBM offers project-based Access Awards for temporary access to a 16-qubit system. Scientists can apply for the program by submitting a project proposal for a technical and merit review, with the expectation that the award will lead to results that will be shared with the scientific community via a publication or conference presentation.
Fluxonium Readout Using Hundreds of Photons | Ioan Pop, Daria Gusenkova & Martin Spiecker (Qiskit Youtube Seminar Series - June 11th)
Speakers: Ioan Pop, Daria Gusenkova & Martin Spiecker Host: Zlatko Minev, Ph.D.
Title: Fluxonium Readout Using Hundreds of Photons
Abstract: We will present a fluxonium qubit implementation based on granular Aluminum (grAl) superinductor strips[1]. Granular Aluminum can be seen as an effective junction array with high kinetic inductance and amenable nonlinearity[2,3]. We report a remarkable resilience of grAl fluxonium qubits to photons populating the dispersively coupled readout resonator. This resilience allows single shot QND measurements[4] and quantum state preparation via active feedback with fidelities exceeding 90% even without using a parametric amplifier[5]. In the last part of the talk we will present recent measurements showing local heating and cooling of the grAl fluxonium mesoscopic environment by stabilizing the qubit in non-thermal states.

The Qiskit Seminar Series is a deep dive into various academic and research topics within the quantum community. It will feature community members and leaders every Friday, 12 PM EDT.
