To incentivize the participation of PhDs and postdocs to IQT Nordics (22-24 June), Nordic Quantum, the University of Oslo, and Thorlabs, have organized a symposium on June 25th to give them the chance to present their work. Thorlabs has even kindly sponsored three researchers to attend IQT Nordics for free!

The speakers have been selected by invite only, but the symposium is open for everyone to attend. Register here if you will attend to make sure you get coffee and cake!

No travel or accommodation support is provided for this event.

5 Generation and Characterization of Nonclassical Light for Quantum Technology

Quantum enhancement in computation, communication, and sensing relies on the generation and control of nonclassical states. Generation of such photonic nonclassical states useful for quantum technology is discussed in the context of quantum state engineering and reservoir engineering. Quadratic Hamiltonians generate and preserve Gaussian states, whose dynamics are completely determined by the first and second moments of the canonical bosonic operators. There are numerous applications of the Gaussian states, but their capabilities are fundamentally limited. Achieving stronger nonclassical properties and quantum advantage requires quantum state engineering or reservoir engineering. As an example of the former case experimental generation of non-Gaussian states after photon addition and subtraction is discussed [1]. Such states are shown to possess photon-number fluctuations in twin beams as well as the corresponding signal and idler beams below the classical limit. These engineered states provide a versatile and experimentally accessible platform for the direct comparison of different quantum operations aimed at producing highly nonclassical and entangled states. Potential of reservoir engineering for singularity enhanced quantum sensing is illustrated by an example of two-mode Gaussian state [2]. The presented framework provides practical guidelines for engineering nonclassical and non-Gaussian states in platforms relevant to quantum communication, sensing, and information processing.

6 Quantum simulation with giant atoms

Superconducting quantum processors require hardware platforms that combine scalability with flexible multi-qubit interactions. Here, we show how giant atoms, artificial atoms coupled to a waveguide at multiple spatially separated points, enable interference-engineered quantum interactions through phase-controlled coupling to propagating photons. By exploiting quantum interference, giant atoms can realize tunable interactions while operating at decoherence-free points. This mechanism enables the implementation of native multi-qubit gates without additional parametric couplers and naturally extends to scalable network architectures. Our results establish giant atoms as a scalable hardware platform for realizing native qubit interactions and multi-qubit gates for quantum simulation and quantum computation.

8 Experimental demonstration of non-local magic in superconducting quantum processor

Magic is a non-classical resource whose efficient manipulation is fundamental to advancing efficient and scalable fault-tolerant quantum computing. Quantum advantage is possible only if both magic and entanglement are present. Of particular interest is non local magic - the fraction of the resource that cannot be distilled (or erased) by local unitary operations - which is a necessary feature for quantum complex behavior. We perform the first experimental demonstration of non-local magic in a superconducting Quantum Processing Unit (QPU). Direct access to the QPU device enables us to identify and characterize the dominant noise mechanisms intrinsic to quantum hardware. We observe excellent agreement between theory and experiment after the inclusion of the dominant noise sources in our system and show the experimental capability of harnessing both local and non-local magic resources separately. This talk will be based on the recent preprint: arXiv: 2511.15576.
