Come work with us! We offer another round of attractive #postdocposition|s and #PhDposition|s in #quantuminformationtheory, on topics ranging from abstract #mathematical themes to pragmatically motivated questions, in an open and stimulating discussion climate. Topics include

- #quantuminformationtheory,
- #quantumerrorcorrection,
- #tensornetworks,
- #quantumalgorithms.

What a wonderfully festive way to end an exciting scientific week, filled with countless stimulating discussions: the stellar PhD viva of Marcel Hinsche, who successfully defended his thesis entitled “Efficient Learning and Testing of Stabilizer States and Processes”, taking us on a fascinating journey through questions of quantum learning and testing.

Congratulations, Marcel, on this outstanding achievement, recognised with the rare distinction of summa cum laude!

Quantum error correction is skyrocketing. But we still need better tools to compile circuits and tailor codes (and, above all, quantum logical protocols) to the hardware they will run on.

In new work published in the @Nature_NPJ Quantum Information (#npjqi), we help close this gap with a mathematical framework and software for compiling hardware-tailored #logical #Clifford circuits for any given stabilizer code.

The key idea: optimize entire logical circuits together. This brings substantial savings in physical two-qubit gates and provides compact starting points for fault-tolerant implementations using flag gadgets. Protecting quantum information is essential. Processing it efficiently is the next challenge.

Warm thanks to Eric J. Kuehnke, Kyano Levi, Joschka Roffe and @dm28295 for the wonderful collaboration on #quantumerrorcorrection.

What a week of great and excellent talks! We have welcomed:

• @armanda_oq from @IcebergQuantum (and formerly our academic team), speaking about “Lifted surgery: Fast processing with QLDPC codes”.

• Cristian Emiliano Godínez Ramírez from our friends and project partners at @IQMquantum, presenting “Four-qubit gate-set tomography”.

• @q_pvricard from our friends at @EPFL_en, speaking about “Dissipation accelerates quantum and classical simulation of open-system dynamics”.

• @DiegoGM_quantum from Johannes Kepler Universität Linz, presenting “Quantum advantage in simulating non-interacting bosons on a digital quantum computer”.

Together, these talks covered a broad cross-section of our current research interests, from #quantumerrorcorrection and tomography and #benchmarking to #quantumsimulation and #quantumalgorithms, connecting academia and industry.

Meet the 2026 Google PhD Fellows.

blog.google/company-news/o…

We are excited that the great @FJSchreiber is now the third member of our team in four years to receive a Google PhD Fellowship in quantum computing, of @GoogleQuantumAI, following @EliesMiquel and @QuAntonioMele. @FU_Berlin has been the first German university to have a recipient in this category.

I am thrilled to announce that my PhD student Franz Josef Schreiber has been awarded a 2026 Google PhD Fellowship in Quantum Computing!

I am very proud of Franz. He is an excellent student working at the interface of quantum computing and artificial intelligence, and seeing his ideas and hard work receive this recognition makes me very happy.

What makes this particularly special to me is that this is the third #GooglePhDFellowship in Quantum Computing for our group at @FU_Berlin, following @EliesMiquel and @QuAntonioMele. Having such wonderful young researchers in the group is one of the great joys of my job. Seeing our students recognised alongside researchers from places such as MIT, Oxford and Berkeley means a lot to me. It shows that with good ideas, persistence and quite a bit of sweat, quantum research at the highest international level is possible here in Germany. I feel proud of what we are building together in #Berlin.

I also deeply value our close scientific ties with colleagues at @GoogleQuantumAI. The exchange of ideas and shared enthusiasm for quantum research mean a great deal to me, well beyond any individual award. Thank you for supporting these excellent young scientists.

Congratulations, Franz! Very well deserved. For more about Franz and the fellowship, see the press release of the Freie Universität Berlin. fu-berlin.de/en/presse/info…
