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.

Today the lab had a virtual sendoff for Muyuan Li (PhD 2020, @GTCSE 🔜 @IBM #IBMQ), Natalie Brown (PhD 2020, @GTPhysics🔜@honeywell), and Mike Newman (Postdoc @DukeEngineering🔜 @GoogleAI). Here is a picture of everyone @QIP2020. #DukeQuantum

Since we couldn't get together in person, we played a virtual escape room together. It was like real life where someone would have the right idea early and everyone would ignore them.

I am going to miss this crew of quantum error correction experts and I wish them the best of luck in their future endeavors.

Congratulations to Dr. Muyuan for a great thesis defense today on Fault-Tolerance on Near-Term QuantumComputers and Subsystem Quantum Error Correcting Codes. Here he is defending his 2017 paper on how physical errors simplify fault tolerant circuits arxiv.org/abs/1702.01155 .

@RichVuduc

Thanks to the committee
@RichVuduc, Edmund Chow, @cd_sherrill
and Brian Kennedy. Muyuan's work was done

@UniversidadCR

I am missing the immediate post thesis celebration but it was great to have Muyuan's collaborators from @UniversidadCR , @IQ_USherbrooke , and @HHU_de be able to join the defense.

Natalie Brown (@GTPhys), Andrew Cross (#IBMQ), and I posted a new paper on leakage errors in the surface code to the arXiv today. arxiv.org/abs/2003.05843 @DukeEngineering #DukeQuantum

Natalie recently defended her thesis on leakage errors. First, she compared whether it was better to have a magnetic field sensitive qubit or a leaky qubit using the standard depolarizing error model for the leaky qubit interaction. arxiv.org/abs/1803.02545

Then Natalie, Mike Newman ,and I realized the physical model of how leaked states and qubit states interact for trapped ion gates is nicer than the standard depolarizing error model. arxiv.org/abs/1903.03937 arxiv.org/abs/1904.10724

@explore_quantum

This is what's worked for me in order to get started with Quantum Computing from scratch:

1/ go through several intro tutorials like #ibmq #qsharp also playing HelloQuantum

2/ go through the textbook algorithms and try to break them down using #ibmq which is the best tool for beginners in my opinion

There are a lot of basic operations to play with in quantum computers. Here is a tweet-length summary of as many as will fit in a twitter thread.

There are also links to the #IBMQ 'Introduction to Quantum Circuits' where you can find out more.

The H or Hadamard gate rotates the states |0〉and |1〉to |+〉and |-〉, respectively. It is useful for making superpositions. As a Clifford gate, it is useful for moving information between the x and z bases.

The controlled-NOT gate acts on a pair of qubits, with one acting as ‘control’ and the other as ‘target. It performs an X on the target whenever the control is in state |1〉. If the control qubit is in a superposition, this gate creates entanglement.
