Cavity quantum optics platform
Quantum optics cavity experiments with solid state materials at 4K
Our microscopic high finesse cavity enhances light-matter
interactions for applications in quantum computation, single-photon
sources, quantum networks and other cutting edge research.
Use our quantum optics platform to sample thousands of inhomogeneous nanosystems like quantum dots, NV-centers, or 2D-Materials in a single run with the ability to perform quantum optics experiments on every single one of them.
Ultra-sensitive absorption microscope
Absorption spectroscopy of low-dimensional materials
Our microscope provides spatial-, spectral-, and time-resolved absorption measurements with exceptional sensitivity.
Measure spectrally and spatially resolved absorption of nanosystems at the parts-per-billion level.
Gain new insight for material research and see what nobody else saw before.

Scanning cavity technology
How our scanning cavity system works:
Our happy customers include
During our work with fiber-based optical microresonators, we realized the enormous power of this technology and its great potential in many research areas. We want to cut down the complexity and time it takes to build and operate an optical fabry-perot microcavity to enable scientists from various fields to boost their research.
On this premise we develop complete setups including highly reflective mirros, mechanical design as well as electronics, software, and consulting to get our customers an operating microcavity setup in various environments as fast as possible. Our ultimate goal is to provide a "turn-key" solution that unlocks the power of optical microresonators in every laboratory.
Qlibri originates from the groups of David Hunger at KIT, Alexander Högele, and Nobel prize laureate Theodor W. Hänsch at LMU Munich and the Max-Planck-Insitute of Quantum Optics, where fiber-based microresonators were pioneered.
Our team provides years of expertise in micro-cavity and nanophotonic research.

First Qlibri Quantum installation
Last week we successfully installed our first quantum optics platform in the labs of Klaus Jöns at Universität Paderborn.
It was an exciting experience. Thanks to all who contributed.

Qlibri GmbH is incorporated
Qlibri GmbH is founded.
Qlibri joins Quantum repeater research project
Qlibri is part of the project QR.X for developing a quantum repeater
link based on color centers in diamond.
We will contribute a stable, actively length-locked and flexible
micro-cavity that can be interfaced with microwave and RF-bias lines.
Milestone in microscopy sensitivity
News from the lab: First complete hyperspectral microscopy image
with noise floor well below 0.001% recorded in less than a second.
First cavity fiber mirrors delivered
Our first micro-mirrors are delivered to our research customers in the US and Spain.
Prestigious start-up funding
We received the prestigious EXIST Forschungstransfer start-up grant
from the German Federal Ministry for Economic Affairs and Climate Action (BMWK).
Live absorption measurement at conference fair booth
We had our first booth at the industry exhibition of the Quantum Science and Information Technologies Fall meeting of the German physical society (DPG).
We showed a live demonstration of absorption microscopy of carbon nanotubes resolving absorption at the 0.0001% level.
We received the prestigious Nano innovation Award from the Center for NanoScience (CeNS).
Live absorption measurement on conference
4.3.2019 On the Single-Molecule Sensors and NanoSystems International Conference we showed the first life absorption measurement of our microscope.
Live stable cavity resonator on conference
We love the challenge. Where other exhibtors just bring dummies to their booths we demonstrated on the European Quantum Technologies Conference in Grenoble 100fm resonator stability of our fully scannable cavity quantum platform
(during the noisy poster session and in our hotel room).
The Idea: a company dedicated to micro-cavities
The idea to build a company offering researchers and industry the power around fiber micro-cavities is born at the LMU in Munich.
