Now out in Applied Physics Letters from CQE lead authors X. Shi (grad student), S.L. Todaro (postdoc), MIT-CQE member Colin D. Bruzewicz, John Chiaverini, Isaac L. Chuang and co-authors ” Ablation loading of barium ions into a surface-electrode trap” Read:pubs.aip.org/aip/apl/article…

Ablation loading of barium ions into a surface-electrode trap

Trapped-ion quantum information processing may benefit from qubits encoded in isotopes that are practically available in only small quantities, e.g., due to low

Jim Hartle passed away. He wrote a wonderful book that helped me learn general relativity As a 22 year old grad student, I spent 6 months at the Institute for Theoretical Physics (ITP) at UCSB, where Hartle was the Director. I was intimidated by him: he was the Director!

I just learned that Jim Hartle unfortunately passed away. You can learn more about him here web.physics.ucsb.edu/~hartle… He visited us a few times in Leuven and I remember him being a very pleasant and friendly person to talk to.

Is it *really* feasible that our intelligence was created by evolution alone? In my latest preprint with @FieteGroup, @MitQuanta, @iaifi_news, I take a little, academia-sized chip out of this question. 🧵⤵️

Whilst #TrappedIons are separated from the bulk of a chip, massively reducing noise, we still face issues with noise! @kenbrownquantum , @MitQuanta , @Berkeley_ions discuss such noise mitagation tactics which will create high fidelity #quantumcomputers arxiv.org/pdf/2009.00568.pdf

This is the new Quantum Security Unit quantum computer, showcasing the longest ion lifetimes yet seen! Just don't tell @IonQ_Inc we lost the key. QV = 2^(0) one ion

Those of us in STEM must do better at breaking down systemic barriers and valuing diversity. Towards this goal, dozens of scholars (including myself) have written an open letter to STEM communities: bit.ly/STEMforBLM_openletter #STEMforBLM
