Happy to join in celebrating #NSF70 with my #NSFstories.
As an undergraduate @univpugetsound at a small liberal arts college, I was unsure what graduate school would be like. Thanks to the @NSF REU at the @UMNews, I was able to join @VPRCramer's lab for the summer and see what grad school life was like at a research university. #SeeNSF
This summer led to my first paper with my grad student mentor @mbsullivan .

I went to @UCBerkeley with my mind set to work with @mhg_group since he was an author of the program I used at Minnesota. When I got there Iearned about quantum computing and started working with Birgitta Whaley on theory problems.
Instead of writing my thesis, in a bold move of procrastination, I started building things in Dan Stamper-Kurn's lab as part of an NSF project yielding my one and only BEC paper. #NSFstories #SeeNSF

After a postdoc @MitQuanta, I landed a faculty job @GTSciences. My first NSF grant was a Center for Chemical Innovation grant with @sabrekais @A_Aspuru_Guzik Daniel Lidar and Peter Love. #NSFstories. We got so much done we wrote a book!

Since moving to @DukeEngineering , I have been delighted to lead the NSF STAQ project. We had a great summer school last year and we are gearing up for a virtual summer school in a few weeks. #NSFstories #SeeNSF #DukeQuantum

I have also been part of the NSF @EPiQCExpedition. This has been a wonderful collaboration with @margmartonosi @prof_chong @quantum_aram @PeterShor1 @schusterqed @nanonoodle #SeeNSF #NSFstories A recent highlight is this ISCA paper with @MartonosiGroup
arxiv.org/abs/2004.04706
There are more #NSFstories from a semester at the NSF funded @KITP_UCSB . I was there when it was still the ITP and my office mate was @bwecht. As you can see we have not aged a day and I borrowed Brian's glasses and never gave them back. #SeeNSF Image

The @bacon-@PeterShor1 code project has been a great collaboration with Chris Monroe's group @JQInews and my group @DukeEngineering @DukePhysics @GTCSE. It is an amazing experiment with excellent control over 13 ions in a chain of 15 ions. Here is a thread about the theory. 1/n
The first error correction code is a concatenation of two repetition codes by @PeterShor1 in 1995
journals.aps.org/pra/abstract/1… 2/n
In 2005, @dabacon (typo in 1/n whoops) was looking for a stable quantum memory and posted a subsystem version of Shor's code arxiv.org/abs/quant-ph/0…. Immediately David Poulin released a paper showing how it connected to the stabilizer formalism arxiv.org/abs/quant-ph/0… 3/n

I agree with @abe_asfaw and @crazy4pi314 that the Bloch sphere doesn't help that much understanding larger quantum systems. However, there is an interesting set of counter examples.
The Bloch sphere needs two non-commuting Pauli matrices. Any two. They could be k-qubit Pauli matrices.
This was used by @nmrqip to show how to use single-qubit composite pulses to make two-qubit gates robust to systematic error.

Our paper on weighted union-find decoding on the toric code is now out in @PhysRevA journals.aps.org/pra/abstract/1…
@Huang_Shilin first developed the weighted union-find decoder to look at the whole family of compass codes but using a slightly non-standard error model. arxiv.org/abs/1911.11317
In this paper (arxiv vesrsion her arxiv.org/abs/2004.04693), Mike and Shilin use the standard error model and find that even truncated weights give great performance.

Congratulations to Pak Hong (James) Leung for successfully defending his PhD on "Robust Ion Trap Quantum Computation Enabled by Quantum Control." @DukePhysics @DukeTrinity #DukeQuantum Image
James had a great collaboration with @kalandsman9 @JQInews where James would invent pulses for two-qubit gates and Kevin would show that they worked in practice.
arxiv.org/abs/1708.08039
arxiv.org/abs/1808.02555
arxiv.org/abs/1905.10421
James worked with an undergraduate Catherine Liang (co-founder duqis.org) and grad students @Huang_Shilin, and Bichen Zhang to optimize digitial implementations leading to great gates @DukeEngineering arxiv.org/abs/2003.12430

The #SummerSTAQ 2020 lecture notes, recorded lectures, problem sets, and discussion sections are now all available openly here. Enjoy and think about joining as a student or lecturer for #SummerSTAQ 2021.
staq.pratt.duke.edu/summer-school
Let me again thank this years lecturers: @quantum_aram (@MIT), Akimasa Miyake (@UNM), Peter Love (@TuftsUniversity), Chris Monroe (@JQInews, @IonQ_Inc ), Abhinav Kandala and David McKay (@IBMResearch, #IBMQ), and Casey Duckering @prof_chong (@EPiQCExpedition @UChicago )
I'd also like to thank the students for joining us for this virtual school.

I am really sorry to hear this but in the spirit of Jon Dowling, I will retell my two favorite slightly irreverent Dowling stories.
When I was a grad student QC funding was the wild west because nothing worked and the government was trying to see if anything worked. This ended in a strange way where some program calls were made and then mysteriously canceled right around when I became a postdoc 2003-4
I think of this as "the first quantum winter" and was bad for QC grad students trying to become faculty in the US. Anyway, the next time there was a call for proposals everyone ignored the last weird time but Jon.
