How does cold milk disperse when it is dripped into hot coffee? Even the fastest supercomputers are unable to perform the necessary calculations with high precision because the underlying quantum physical processes are extremely complex.

In 1982, Nobel Prize-winning physicist Richard Feynman suggested that, instead of using conventional computers, such questions are better solved using a quantum computer, which can simulate the quantum physical processes efficiently—a quantum simulator. With the rapid progress now being made in the development of quantum computers, Feynman’s vision could soon become a reality.

Together with researchers from Google and universities in five countries, Andreas Läuchli and Andreas Elben, two theoretical physicists at PSI, have built and successfully tested a new type of digital–analog quantum simulator.

Quantum computing represents a paradigm shift in computation with the potential to revolutionize scientific discovery and technological innovation. This seminar will examine the roadmap for constructing quantum supercomputers, emphasizing the integration of quantum processors with traditional high-performance computing (HPC) systems. The seminar will be led by prominent experts Prof. John Martinis (Qolab), Dr. Masoud Mohseni (HPE), and Dr. Yonatan Cohen (Quantum Machines), who will discuss the critical hurdles and opportunities in scaling quantum computing, drawing upon their latest research publication, “How to Build a Quantum Supercomputer: Scaling Challenges and Opportunities”
