*** New Publication in Science *** Entanglement today is THE tool of quantum information science. But it is highly sensitive and it is an enormous challenge to entangle resting qubits (atoms) with flying qubits (photons) "at the push of a button" - necessary to propagate entanglement in a quantum network. A team in the Quantum Dynamics Division at MPQ has now succeeded in doing exactly that with atoms connected in parallel. Using optical tweezers in a cavity, the team was able to individually control up to six atoms and entangle each with a photon. By applying a multiplexing technique, the scientists could thereby demonstrate an atom-photon entanglement generation with almost 100 percent efficiency, a groundbreaking experimental achievement and an a major step towards a future quantum internet. The work is published today in the journal Science. ➡ https://lnkd.in/d6yuJctN

It's a pretty sweet way to start the week for planqc. The startup has just raised €50 million in a Series A funding round - an amazing new milestone in the company's still very early years, just 18 months after it was founded as a spin-off startup from MPQ. 👏 Building on decades of pioneering research and expertise at the Max Planck Institute of Quantum Optics, planqc is well equipped and on route to delivering highly scalable and fault-tolerant quantum computing based on neutral atoms. We are excited to see what comes next! Congratulations to the team! 🥂 More info: https://lnkd.in/dSy6EYnd

*** Congratulations *** to Vitaly Wirthl, former PhD now Postdoc at MPQ, for receiving this year's Theodor Hänsch Dissertation Prize from the Faculty of Physics at LMU Munich – Ludwig-Maximilians-Universität München. In his work, Vitaly Wirthl succeeded in measuring a specific energy transition in deuterium, the heavy hydrogen, more precisely than ever before. Ultra-precise measurements such as these enable a direct comparison and test of the theory of quantum electrodynamics, and provide important clues, for example in the search for new physics or the exact determination of natural constants. The final evaluation of Vitaly Wirthl's new data is currently being eagerly awaited by precision physicists. https://lnkd.in/daQKj-d3

*** This week in Nature *** Physicists at MPQ have achieved a major breakthrough in the development of quantum computers and a quantum internet. Using single atoms in a cavity as photon emitters and a fusion gate process, the researchers were able to generate unprecedented complex photonic multi-qubit entanglement structures – the so-called graph states. The fusion process itself uses a cavity-assisted gate between two atoms. The technique is, in principle, scalable to even larger numbers of qubits and is the decisive step towards, for instance, a memory-less quantum repeater in a future quantum internet. ➡ More Information: https://lnkd.in/e9DdYZwX ➡️ Link to the paper: https://lnkd.in/eTx_uKdX
