A thread about conical intersections. When the pandemic started, all the experimentalists, including Jacob Whitlow and Zhubing Jia, were kicked out of lab. I suggested that Jacob and Gloria think about whether or not we could simulate conical intersections with our ion traps.
It’s been a few year since @IvanKassal and I talked about CIs over lunch and I moved to🇨🇭in the meantime. Now, with the hard work of many talented people, this analog QSim finally turned into reality. I am very proud of the teams @Sydney_Science @ARC_EQUS that made it happen!
📰Paper alert! "Direct observation of geometric phase in dynamics around a conical intersection" Geometric phases are counterintuitive and affect the outcomes of chemical reactions, but have never been directly observed... until now! Preprint: arxiv.org/abs/2211.07320
Only one more week until the #Quantum Industry Day in Switzerland, proudly supported by @ETHQuantumCntr It is not too late to sign up for the in-person event #QuantumComputing #QuantumSensing #QuantumCommunication and more, go to qidis22.b2match.io
Another exciting result from our very fruitful collaboration on simulating chemical dynamics between @SydneyChemistry @IvanKassal’s group and the quantum control laboratory @sydney_physics !

🚨 Job Alert 🚨 We are looking for a #SoftwareEngineer at the @ETH_en - @psich_en #Quantum #Computing Hub! emea2.softfactors.com/job-opening/rg…
@Ion_busters We have actually used RAP to measure the Fock state population in this way a couple of years ago when demonstrating EIT cooling with 18 ions. The technique was very well hidden in our paper, however: arxiv.org/abs/1603.05568
The #Quantum Industry Day in Switzerland is back in person this year! Oct, 4th at Technopark, Zurich. Save the date and sign up here qidis22.b2match.io @ETHQuantumCntr @IBMResearch @IDQuantique @CSEMInfo @Zhinst @SwissEuresearch @NCCR_QSIT @nccrSpin

Apply for the 2nd Quantum Computing Hard- and Software summer school, 13-17 June @EPFL_en! Deadline April 22. Supported by us and the @ETHQuantumCntr, this program will bring Master's and PhD researchers to study quantum computing technologies. qchs2022.epfl.ethz.ch
@Tonyransford @DavidHa03746758 Again, our focus is on ultimate detection fidelity, if you managed to shelve to the F state. We suggest a few ways to do that as the D state decay you mention is limiting, otherwise.
@Tonyransford @DavidHa03746758 Point taken, we did not measure SPAM in the way you did but just how well we could separate the two populations - using the same technique you also pursued, we just did not think that 200 ms of shelving per shot is reasonable for any practical use…
Still looking for something to do today? Look no further! Come by #SwissScienceCenterTechnorama, and see single atoms ⚛️ Also meet our team and ask all of your burning questions. Thanks to @ETH_physics, @snf_ch Agora, and Technorama for making this possible!
@DavidHa03746758 Erm, about that… arxiv.org/abs/2012.14606
We have an open #postdoc position in the ion trap section of the @ETH_en - @psich_en #Quantumcomputing Hub. Come join us to work on ion traps with integrated photonics. Apply here: bit.ly/3KiLBJI to work on devices like this one: ethz.ch/en/news-and-ev…
