QUBIG GmbH

Role in the consortium

Within the MUNIQC-Atoms project, QUBIG develops high-performance light conditioning tools for the temporal shaping of laser pulses in the UV and visible regime.  Our goal is to create novel laser beam conditioning systems that enable the fast and precise control of strontium-88 atoms trapped in optical lattices using electro-optic technology tailored for this system.

Partner expertise

QUBIG GmbH is a technology company specializing in the field of scientific lasers with a focus on the development and manufacturing of high-end free-space light-modulators and dedicated electronics for high-precision control of all properties of laser light, such as its frequency, phase, amplitude, polarization, and position. QUBIG provides tools for a broad range of applications for wavelengths from the Ultraviolet (200nm) to the Infrared (10μm), for optical power starting from single photons up to several watts, and modulation frequencies from DC up to 20 GHz.

Our team combines profound expertise not only in the areas of laser technology, crystal-optics, and HF/HV electronics but also possesses in-depth knowledge and many years of experience in various fields of quantum technologies such as laser cooling and trapping of atoms/ions/molecules, Bose-Einstein condensation / degenerate Fermi gases,  quantum information, etc. The broad knowledge enables our R&D team to develop tailored state-of-the-art light conditioning tools for the most demanding applications such as quantum computing [1-4], control of neutral atoms and trapped ions [5,6], and optical clocks [7,8].
