Quantum simulator enables first microscopic observation of charge carriers pairing

Using a quantum simulator, researchers at the Max Planck Institute of Quantum Optics (MPQ) have observed pairs of charge carriers that may be responsible for the resistance-free transport of electric current in high-temperature superconductors. So far, the exact physical mechanisms in these complex materials are still largely unknown. Theories assume that... more

Marcel Duda invents a novel method to produce fermionic polar molecules

His doctoral thesis focused on the production of fermionic polar molecules from potassium and sodium atoms. Contrary to previous assumptions, he was able to show that the molecule production procedure is both possible and highly efficient. Well done! more

Lighthouse project "Networked Quantum Systems" (NeQuS) takes up work

“NeQus” is a new joint project as part of the Munich Quantum Valley, in which scientists from the TUM, LMU, MPQ, WMI, BAdW), and WSI are working together to connect different quantum systems - atoms in a vacuum, quantum dots, superconducting quantum bits, and dopant atoms in silicon. more

Physics Breakthrough of the Year 2022: The Speed Limits of Optoelectronics

The physicsworld magazine has chosen the recent research of Dr. Marcus Ossiander and Dr. Martin Schultze as one of the top ten breakthroughs of 2022. With their paper "The speed limit of optoelectronics" published in March 2022, they have explored the limits of optoelectronic circuits. more

NISQ-Computer: Quantum entanglement can be a double-edged sword

NISQ computers need quantum entanglement as a key resource to perform computations. But the presence of entanglement can also in some cases be a threat to their accuracy, like a recently published paper shows. more

More control over plasma accelerators

LMU Physicists at the Centre for Advanced Laser Applications (CALA) have combined two plasma-based methods of particle acceleration for electron beams: a laser-driven wakefield accelerator (LWFA) with a particle-beam-driven wakefield accelerator (PWFA). With this combination, they achieve better stability and higher particle density for electron beams than with just a single plasma accelerator. more

Roman Bause and his team develop new cooling method for polar molecules 

With his dissertation project, he contributed significantly to the development of a new microwave technique that allows polar molecules to be cooled to record low temperatures, a few nanokelvin above absolute zero. Congratulations! more

Theodor Hänsch receives honorary doctorate from ETH Zurich

On 19 November 2022, MPQ Director Theodor Hänsch received an honorary doctorate from ETH Zurich. The award honours “his outstanding scientific work that has had such a huge impact on the entire field of modern atomic and molecular physics, especially laser cooling of atoms, and laser-based precision spectroscopy." more

Kerry Vahala receives „MPQ Distinguished Scholar“ award

Kerry Vahala, Professor of Applied Physics at the renowned Caltech Institute in Pasadena, California, today receives the latest edition of the „MPQ Distinguished Scholar“ certificate. He receives the award in recognition of his "pioneering scientific work in the field of nonlinear optics and photonics with microresonators".  more

Optica announces new "Theodor W. Hänsch Prize in Quantum Optics"

The Optica research society has announced a new scientific prize: Named after Theodor Hänsch - Director at MPQ, Professor at LMU and Nobel Laureate in Physics - the 20,000 US dollar research prize is aimed at young scientists working on innovative projects in the field of quantum technologies. more

Erbium atoms in silicon: A prime candidate for quantum networks

A team of researchers at the Max Planck Institute of Quantum Optics has laid the foundation for the development of future quantum networks. The scientists embedded individual erbium atoms in crystalline silicon, creating ideal conditions for storing and passing on quantum information. more

New Hardware for Quantum Networking

Researchers at the Max-Planck-Institute of Quantum Optics and the Technical University of Munich have demonstrated that individual atoms in a thin crystalline slab can be resolved and individually controlled using light of a precisely adjusted color. This will enable the exchange of quantum information between them in order to create extended quantum networks. more
