We plan to return partly to in-person talks. These talks will be held in the interim lecture hall B 0.32 at MPQ and can additionally be attended online. Some talks remain online only.

2G regulations apply to in-person talks, i.e. every time you wish to participate in person, you will have to prove, e.g. with the CovPass-App, that you are vaccinated or recovered.Whether facemasks have to be worn inside the lecture hall will be communicated in the the e-mail announcement for each talk separately. In any case, you will need a medical facemask in the hallway. Audience not affiliated with MPQ are welcome to join in person as long as they meet 2G criteria.

Details on how to participate online are distributed via the mailing lists [wiss-mpq] and [Mpq-colloquium-stream]. To receive this information, please register using the adjacent link.

Scientific organization of the talks:  Dr. Stephan Dürr and Dr. Thomas Udem

Location: +++ONLINE TALK+++

+++ONLINE COLLOQUIUM+++ Infrared photon counting with superconducting nanowires (Prof. Robert Hadfield)

A host of emerging 21st century technologies rely on the ability to detect single photons at infrared wavelengths. Photon counting is an essential tool in quantum optics experiments. Quantum key distribution allows secure communications over long distance fibre optic networks or even from ground to space. [more]

+++ONLINE COLLOQUIUM+++ The 3rd quantum revolution: Quantum Algorithmic Experiments (MCQST-Colloquium) (Prof. Dorit Aharonov )

Following the second quantum revolution, which had completely undermined how we think of algorithms, the last decade gave birth to a third quantum revolution - which has changed the way we think of physical experiments. I will demonstrate this with some examples of how quantum computational ideas such as quantum error correction and quantum algorithms can be used to enhance conventional quantum experiments, to achieve increased efficiency and precision in sensing, metrology, and more.

+++ONLINE TALK+++ Novel avenues for robust free-space quantum communications (Prof. Thomas Jennewein)

Quantum information processing and quantum communication are novel protocols that originate from the very fundamental and philosophical questions on superposition and entanglement raised since the early days of quantum mechanics. Strikingly, these new protocols offer capabilities beyond communication task possible with classical physics. [more]
