Questions to address
• Does quantum engineering require its own department, or is it better implemented as a specialized track in existing engineering disciplines?
• How can we build affordable hands-on quantum education at the undergraduate level?
• What courses should be included in a quantum engineering major or minor?
• How do we increase diversity in our quantum engineering students?

Does quantum engineering require its own department, or is it better implemented as a specialized track in existing engineering disciplines?
• Extremely diverse topic
• Very different types of expertise fit within QISE
A few examples• Superconducting QC; expertise:
• RF engineering, physics, QEC, q. algorithms expert, … • Quantum network science
• Theory of communication, classical networks, entanglement, cryptography, …, but also, implementations: emitters, devices, linear/nonlinear optics, transduction, …
• Sensing using color centers; expertise: • Engineering/nanophotonics, physics, materials science, …

How can we build affordable hands-on quantum education at the undergraduate level?
• Leverage existing resources/programs
• Select future investments judiciously
• Shared facilities?
![Page 5: Developing Practical QISE Education at the Undergraduate Level](https://reader030.fdocuments.in/reader030/viewer/2022032322/62318706a3e17e279423c06d/html5/thumbnails/5.jpg)
Expertise to acquire
• Field at very early stage à firm grasp of fundamentals is crucial
• E.g., specialized programming software of particular processors could become obsolete quickly
• Leverage tools provided by industry without narrowing focus too much; “low-level” knowledge still critical
• Domain expertise compliments quantum skills
![Page 6: Developing Practical QISE Education at the Undergraduate Level](https://reader030.fdocuments.in/reader030/viewer/2022032322/62318706a3e17e279423c06d/html5/thumbnails/6.jpg)
Challenges
• Cost• Experimental setups expensive• For some experiments, demos can be purchased• For more complicated experiments (e.g., involving dilution
refrigerators) very difficult to include in a scaled up program• Shared facilities?
• Teaching staff
• Creating a meaningful curriculum given how broad the field is
![Page 7: Developing Practical QISE Education at the Undergraduate Level](https://reader030.fdocuments.in/reader030/viewer/2022032322/62318706a3e17e279423c06d/html5/thumbnails/7.jpg)
Additional challenges at graduate level
• Masters level: short time, need to choose focus; each university should focus on leveraging faculty expertise
More in Bob Joynt’s talk
• PhD level: • Physics programs very rigid• Engineering departments probably lack critical mass of QISE faculty
• Leveraging existing interdepartmental resources/curriculum most likely the way to go

QISE is one of the most interdisciplinary fields
Great opportunity and big challenge!
![Page 9: Developing Practical QISE Education at the Undergraduate Level](https://reader030.fdocuments.in/reader030/viewer/2022032322/62318706a3e17e279423c06d/html5/thumbnails/9.jpg)
The potential pitfalls of interdisciplinary programs
• Too restrictive
• Students have diverse backgrounds, strengths and weaknesses
• Prerequisite hell
![Page 10: Developing Practical QISE Education at the Undergraduate Level](https://reader030.fdocuments.in/reader030/viewer/2022032322/62318706a3e17e279423c06d/html5/thumbnails/10.jpg)
Specialization is unavoidable and actually helpful!
• Not everyone can (or should) be taught everything
• Topics considered absolutely necessary by a typical physicist or engineer may not be in every student’s curriculum. E.g.:• QISE students may never solve the Schrödinger equation for continuous
problems and may never work on time-dependent problems• Some students may not touch any experiments• Some students will not take EM
• There are fundamentals to which everyone should have exposure
![Page 11: Developing Practical QISE Education at the Undergraduate Level](https://reader030.fdocuments.in/reader030/viewer/2022032322/62318706a3e17e279423c06d/html5/thumbnails/11.jpg)
• Multidisciplinary interest and expertise (7 depts involved)• Opportunity for an interdisciplinary program• Provide flexibility • avoid issues with prerequisites, etc• Students can tailor degree to their interests & background
• Absolutely necessary knowledge• Linear algebra• Programming & collaborative software• Quantum computing and quantum communications fundamentals
Virginia Tech approach-I

• Mandatory courses• Linear algebra• Programming (classical and quantum computers)• Quantum computing and information concepts (freshman level)• Quantum information technologies—hardware agnostic (senior level)
• Electives set 1 (quasi-mandatory)• Out of short list of quantum-focused courses select at least one (hardware/software)
• Electives set 2• Long list of domain-specific courses (freshman-junior level), select at least one
• Electives set 3• Long list of domain-specific courses (mostly senior level), select at least one
• Optional project: choose among (i) academic research, (ii) industry/national lab internship, (iii) outreach*
*VT has multiple “5+ Club” awards for graduating five or more physics teachers in a given year
Virginia Tech approach-II

• Build (unofficial) specializations (enforced via structure)
• Examples• Experimental/engineering (QM, solid state, lab courses)• Cryptography (classical and quantum crypto courses; no need for QM)• Chemistry (classical and quantum algorithms for chemistry, QM, many-body)• Machine learning/data analytics/QIS
• Can build a range of specializations: flexible but substantial
• Students will maintain contact with each other and build community through course involving collaborative projects

Freshman QISE course structure
• Applications/concepts-first approach: excite students, peak their interest, decouple concepts from mathematical framework
• Friendly pictorial approach (no advanced math required)
• But rigorous!
• Build toward linear algebra
• Use IMB Quatnum drag-and-drop interface (no coding experience required)

• Analog of Deutsch’s algorithm• Allows students to see a
concrete example of something that can be done with quantum but not classical bits

From pictorial formalism to linear algebra
,
Motivate need for linear algebra instead of starting with it!E.g. superposition state |+>:
1,1 [1 1]1211
• Clouds à lists à vectors (+normalization)• Similarly for multi-qubit states• Shows tensor product structure naturally• Translate boxes to matrices: also natural, as linearity is already built into the rules

Summary of VT degree structure
• Early exposure to quantum concepts (friendly but rigorous)
• Very small set of courses that are mandatory across all students
• Restricted set of electives with structure (e.g., out of small sets of courses take at least 1, etc)
• Broader set of electives with more freedom to construct a degree that includes domain knowledge (and in case of QISE minor aligns with major)

How do we increase diversity in our quantum engineering students?
• Resources available• Access to hardware and software• Online learning• Due to covid, lots of conferences, workshops virtual & talks posted online
• Potential issue with further imbalance based on gender and race
![Page 21: Developing Practical QISE Education at the Undergraduate Level](https://reader030.fdocuments.in/reader030/viewer/2022032322/62318706a3e17e279423c06d/html5/thumbnails/21.jpg)
Toward a diverse QISE community
• Early outreach (K12, summer camps for HS students, transition programs )
• Target diverse/underrepresented groups
• QISE researchers should be careful with hype, aggressiveness, and competitive or esoteric language
![Page 22: Developing Practical QISE Education at the Undergraduate Level](https://reader030.fdocuments.in/reader030/viewer/2022032322/62318706a3e17e279423c06d/html5/thumbnails/22.jpg)
Outreach in collaboration with engineering, VT
• VT Center for Enhancement of Engineering Diversity (CEED)
• C-Tech2 program: 2 week STEM camp for 60 high school girls from all over US
• Barnes, Economou introduced a QISE module: 2-day event
