Quantiki

SoftQuantus is a European deep-tech company building QCOS (Quantum Control Operating System), focused on benchmarking, reproducibility, and operational reliability for quantum computing infrastructure.

We are opening a private investment seat associated with a European Board Member (Non-Executive) appointment for a qualified investor who can support long-term governance, strategic oversight, and institutional credibility.

SoftQuantus is building next-generation quantum infrastructure in Europe, with a long-term objective of developing scalable trapped-ion quantum computing systems focused on stability, reproducibility, and operational reliability.

We are seeking a PhD-level experimental physicist to join as a technical cofounder and lead the hardware development effort.

Role Overview

The Founding Quantum Hardware Scientist will:

Lead the design and construction of a trapped-ion experimental platform

Architect scalable ion trap systems (e.g., Yb⁺ or Ca⁺)

About this role
SoftQuantus is developing QCOS, a Quantum Control Operating System focused on benchmarking, reproducibility, drift analysis, and hardware reliability. We are seeking a PhD-level Scientific Advisor to help shape the scientific foundation of our platform.

The Trapped Ion Quantum Technology Group at Stockholm University is seeking a postdoctoral researcher to contribute to our research in open-system quantum simulations with trapped Rydberg ions. This position is part of the ERC Synergy project "Open 2D Quantum Simulator (OPEN-2QS)".

The Department of Physics and Astronomy at Rice University seeks to hire a Postdoctoral Research Associate in the field of Quantum Foundations & Simulation, associated with the Q‑Ontic Initiative—an interdisciplinary project at the interface of quantum foundations, computational physics, and physics education.

The position focuses on the development of interactive, web‑based simulations that explore alternative representational and interpretive frameworks in quantum mechanics. Research areas include conceptual analysis, visualization, and comparative study of empirically equivalent quantum models. A prototype model can be explored at qsf‑v1.

QLAB is a newly established research center at the University of Warsaw, funded by the Foundation for Polish Science (FNP) under the International Research Agenda (MAB) programme with European Funds for a Modern Economy (FENG). Our mission is to develop scalable hybrid quantum-classical technologies for secure communication, efficient computing, and ultra-sensitive measurement and imaging systems.
We collaborate with leading international scientific partners (Sorbonne University, ETH Zurich, University of Vienna) and industry partners (PCSS, Google Poland, Orange Poland, IQM) to bridge the gap between cutting-edge research and real-world applications.

Epitaxial semiconductor quantum dots are among the best sources of quantum states of light. They deliver single photons and entangled photon pairs with high brightness and indistinguishability. We have recently established new methods for their coherent optical control and excitation with the goals of improving robustness and coherence. In the Austrian Science Fund (FWF) project BRAIDS we are working towards the generation of time-bin entanglement via dark exciton states.

The Quantum Photonics Laboratory seeks a talented scientist to undertake research on the demonstration of an efficient interconnect between a quantum dot single photon source and a solid-state quantum memory. Significantly, the goal of the project is to achieve storage of large bandwidth photons in the telecom band into an on demand photonic quantum memory based on rare earth doped crystals.
