Application Panels at World of Quantum 2025
A comprehensive and attractive forum program of presentations
At this year’s World of Quantum (June 24–27, 2025), part of LASER World of PHOTONICS in Munich, attendees can look forward to a dynamic and insight-rich program hosted at the Forum World of Quantum and Insights Forum. These forums will spotlight cutting-edge applications in quantum technologies through expert-led lectures, panel discussions, and technology pitches. TOPTICA Photonics is proud to contribute to the Application Panel Program. June 25, 2025 | 14:30–16:30 Quantum computers are approaching their first industrial applications. Advances in scalability and error correction are paving the way for more robust and economically viable systems. New approaches such as Rydberg quantum computers offer promising perspectives for optimization problems due to their scalability and efficient coupling mechanisms. At the same time, superconducting, trapped-ion, and photonic architectures continue to evolve. Improved error correction enhances the stability of logical qubits. A key focus is the development of application-specific hardware platforms. While a universal, fault-tolerant quantum computer remains a long-term vision, hybrid architectures are already providing economic benefits by integrating quantum computing with classical high-performance computing. Co-designed hardware-software solutions are optimizing applications in materials science, logistics, and finance. June 26, 2025 | 10:00–12:00 Quantum technology experiments and applications place the highest demands on classical technologies, some of which are novel, robust, and optimized for specific applications. These key technologies enable the preparation, control, and readout of complex quantum systems and are a central building block for the establishment of a quantum ecosystem. Among the key technologies are a variety of optical technologies such as lasers, photon sources, optical (measurement) systems or photonic integrated circuits. In addition to these, electronic components (detectors, timing units, modulators), cryogenics, and custom component fabrication are essential for the future implementation of quantum technology applications. The session will provide an overview of recent developments in key technologies for quantum solutions. Go to world-of-quantum.com for more details |
