For the last #MLS of 2020, Akshay Koottandavida is presenting his work on "Experimental Implementation of Pair-Cat Code with Superconducting Microwave Circuits" with the warmest background while we wait for the first snow storm of winter

Congrats to Alexandre Blais, Alexandre Blais Theory of Superconducting Quantum Devices group Institut quantique Université de Sherbrooke, and his team who are top collaborators of Quantum Device Lab ETH Physics ETH Zurich with many exciting joint pulications since more than 15 years!

GKP codes are well known to be excellent against loss, but they are poor against dephasing. Below are results for optimal recovery of a square GKP codes against loss vs loss+dephasing. The x-axis shows the average photon number, i.e. the "size", of the GKP code.

Big congrats, Shruti Puri

When you have colleagues with artistic spirits in lab:

Delighted to talk with the Yale University Undergraduate Quantum Computing (YuQC) yaleqc YaleQuantumInstitute club this week on To catch and reverse a quantum jump mid-flight. Tune in :) yaleqc.com nature.com/articles/s4158… #qubit #QuantumComputing

Our new preprint from first author Volodymyr Sivak and others at YaleQuantumInstitute on model-free quantum control with reinforcement learning now on arxiv, check it out here! arxiv.org/abs/2104.14539

Sunshine is on the move to his new house! After pushing the boundaries of knowledge with researchers, their new mission will be to teach the public about quantum computing through YQI outreach programs.

As a former rocket scientist, I approve this message! "Understanding this stuff really is possible — after all, it isn’t rocket science; it’s just quantum computing!" quantamagazine.org/why-is-quantum…

Nicholas Frattini is defending his PhD and will present his working on Three-wave Mixing in Superconducting Circuits: Stabilizing Cats with SNAILs. We wish him good luck!

Excited to share our new open-source quantum instrumentation control kit (QICK), developed with Fermilab, with @physicsfpgaeda, and Andrew Houck (and others without twitter accounts). The paper is at arxiv.org/abs/2110.00557 and the firmware/source is at github.com/openquantumhar…

Check out our new preprint on arxiv! With Volodymyr Sivak Andy Ding Baptiste Royer and others at @QlabYale YaleQuantumInstitute we show universal control of an oscillator coupled to a qubit can occur much faster than is usually assumed by using large oscillator displacements arxiv.org/abs/2111.06414

A highly-optimized version of the surface-GKP code is introduced, showing how to ease the requirements to achieve fault-tolerance and prepare the necessary GKP state. Kyungjoo Noh @QuantumChambs Fernando Brandao Amazon Web Services go.aps.org/3r7GIfQ

Congratulation to YQI Member Michel Devoret for winning the 2021 Micius Quantum Prize! @QlabYale news.yale.edu/2022/03/01/yal…

Our work is now published in PRX Quantum! journals.aps.org/prxquantum/abs… I'm also starting my own group next summer in Sherbrooke Institut quantique 😀If the work above is interesting to you, I'm looking for graduate students.

Congratulations to Prof. Liang Jiang, who accepted the 2022 Rolf Landauer and Charles H. Bennett Award in Quantum Computing this week during the APS March Meeting. The award recognizes exceptional contributions in quantum information science. Read more: pme.uchicago.edu/news/physicist…

Happy to share our work from @QlabYale YaleQuantumInstitute on universal control of an oscillator with weak dispersive coupling to a qubit is now published in Nature Physics. Check it out here: nature.com/articles/s4156… Volodymyr Sivak Baptiste Royer Andy Ding

Big day at YQI, Volodymyr Sivak is defending his PhD thesis on Quantum Error Correction Beyond Break-Even. We wish him good luck!
