ML4Q&A - from the lives of quantum physicists

In this episode of ML4Q&A, hosts Chandana Rao and Mira Sharma speak with Dr. Lars Schreiber (RWTH Aachen University), along with his PhD students Mats Volmer and Max Beer, about the challenges of scaling silicon-based spin qubit quantum computers. Lars Schreiber shares insights into why semiconductor platforms despite their technological maturity have not yet achieved large-scale quantum systems.

The conversation explores the practical realities of building spin qubit devices, from material imperfections and device variability to the difficulty of controlling millions of qubits. Mats and Max discuss their work on conveyor-style spin-qubit shuttling and T-junction architectures for routing qubits in...

In this episode of ML4Q&A, hosts Chandana Rao and Patrick Geraghty speak with Professor Daqing Wang about his journey through experimental quantum science and the challenges of building cutting-edge quantum technologies. Wang reflects on his early experience contributing to a landmark experiment that demonstrated quantum teleportation over 143 kilometers between the Canary Islands, describing what it was like to join such a high-impact project as a master’s student and the practical challenges involved in detecting fragile quantum signals over long distances.

The conversation explores the realities of running demanding quantum optics experiments, from dealing with noise and imperfect equipment to...

Michaela Eichinger, Product Solutions Physicist at Quantum Machines and quantum content creator, joins Mira and Chris on ML4Q&A to discuss her journey from academic research to working in a deep-tech startup. She is representative of a generation of PhD students and postdocs from labs working on qubit technologies that join the emerging quantum industry. Her PhD work focused on gatemons and stencil-based nanofabrication of superconducting qubits at the Niels Bohr Institute. Now she works at Quantum Machines, a company developing control electronics for quantum computers that aims to provide hardware capable of meeting the demands of fault-tolerant quantum architectures.

Jens Eisert joins ML4Q as a member for the next funding period which was granted around the time Chris and Mira recorded this Episode with him. So naturally, they discuss the German Excellence Initiative and how joining ML4Q was a natural step for Jens, given he has many previous and ongoing collaborations with other ML4Q members.

Jens shares his insights on various aspects of quantum information processing such as benchmarking and no-go theorems, his recent white paper on AI and quantum computing, quantum error correction, complexity and pseudo chaos. Ultimately Jens makes a convincing case that quantum computers remain fascinating...
