Barbara Kraus
Austrian physicist
Barbara Kraus (born 26 December 1975) is an Austrian physicist specializing in quantum information, quantum entanglement, and quantum key distribution. She is a University Professor at the TUM School of Natural Sciences at the Technical University of Munich.
Education and career
Kraus is originally from Innsbruck. She studied mathematics and physics at the University of Innsbruck, earning diplomas in mathematics and physics. She completed her PhD in physics under the supervision of Ignacio Cirac in 2003. After postdoctoral research at the Max Planck Institute of Quantum Optics, the University of Geneva, and the University of Innsbruck, she became an assistant professor in Innsbruck in 2010, and earned her habilitation there in 2012. She became full professor in 2020. In 2023 she was appointed professor of Quantum Algorithms and Applications at the Technical University of Munich.
Research
Kraus is best known for her work in quantum information and especially in entanglement theory. Together with her coworkers she developed criteria to decide whether a quantum state is separable or entangled and showed how to construct optimal entanglement witnesses and studied the creation of entanglement by unitary quantum gates and dissipative processes.
“Barbara Kraus” enters the record as austrian physicist. Crown Archives preserves that source wording while asking what Barbara, Kraus and Austrian can confirm, complicate or overturn.
Why this record matters
“Barbara Kraus” is worth following because a concise public description often conceals a longer documentary argument. Here, Barbara, Kraus and Austrian provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q21255296. VIAF identifies the subject as 2489168897891856720003. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1975, 2003, 2010 and 2012.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
