PhD in Physics: Attosecond Physics, Quantum Information and Ultrafast Nonlinear Control Lund University in Sweden

The Division of Atomic Physics at Lund University is seeking one doctoral student for research in attosecond physics within a strong interdisciplinary environment linked to the Lund Laser Centre . The division works across optics and lasers, ultrashort light pulses, high-intensity laser-plasma physics, quantum information, and biophotonics, and operates the High-Power Laser Facility with advanced femtosecond laser systems alongside collaborations with free-electron laser facilities. This PhD pro...

This PhD project will develop high-bandwidth quantum frequency converters for future hybrid quantum networks. The research addresses a central challenge in quantum networking: quantum technologies often operate at incompatible optical wavelengths. Visible single-photon sources, telecom communication channels and atomic quantum memories therefore require interfaces capable of translating photons between wavelength regimes. The project will use four-wave mixing in warm rubidium vapour to develop t...

Uppsala University invites applications for a full-time postdoctoral position in quantum matter theory , specializing in unconventional superconductivity and quantum geometry. The appointment is based in the Department of Physics and Astronomy within the Quantum Matter Theory research program and will be located in Uppsala, Sweden. The successful researcher will join Prof. Annica Black-Schaffer's research group, which studies quantum condensed matter, unconventional superconductivity, topologica...

This four-year PhD project in advanced signalling and detection in quantum communications explores how quantum communication systems can remain effective when quantum states and communication channels are uncertain. The research will design and optimise resilient quantum signalling constellations for conveying classical information. In particular, the project will investigate constellation designs that maximise minimum trace distance and uniform Holevo-x information, addressing the limits impose...

Chalmers University of Technology is seeking a postdoctoral researcher to join the Department of Mathematical Sciences, Division of Analysis and Probability, in Gothenburg, Sweden. The department brings together research in mathematics and related fields in an international, collaborative environment involving the University of Gothenburg and Chalmers. The project focuses on fundamental and applied problems in quantum information theory , with the specific direction shaped jointly with the succe...
