Introduction to quantum information and computing. Prerequisite Phys. 214 or equivalent. We will introduce quantum bits (qubits), quantum gates, and quantum algorithms; use online quantum computers to do calculations; discuss current technology.

Course material

We will use smartIllinois (smartPhysics); to get started just click on the link!

We will also use the gradebook to keep track of scores.

iClicker cloud

We will use the phone-based iClicker App ("iClicker Reef" in the App Store and Google Play) in class.  There is a small charge to use this App.

Please go to to get started.

If you have used the App previously, sign in.

If this is your first time using this application, click the "Create an Account" link at the top.  Please use your email address to create an account.  Once logged in, click the plus sign in the upper right-hand corner of the screen.  Enter "University of Illinois at Urbana" for your institution, Physics for the Department, Phys370 as the course name.  The join code is

Class forum

We will use Campuswire to ask and answer questions outside of class time--I encourage you to do both!  You will receive an invitation email close to the start of the semester.

HW submission

HW assignments are on the smartIllinois pages.  Submission will be via the course Gradescope page; choose Phys 370.  There is nothing to submit for homework on the smartIllinois pages.


Exams for this course will be in-class/in-person.  Dates are on the smartIllinois pages.  The two midterm exams will be 80 min; the final exam will be 180 min.


The course will comprise weekly homework (25%), final exam (25%), two midterm exams (15% each), pre-class reading and checkpoint questions (10%), and class participation (10, 9, 7, 4, 0% for 0, 1, 2, 3, 4 absences), recorded in the course gradebook. The late homework policy is 20% reduction if submitted less than 2 weeks late and before the final course deadline, whichever is earlier. There are bonus points (maximum 3%) for checkpoint questions answered correctly in class. The (lower) grade boundaries will be A+ (97), A (94), A- (91), B+ (88), B (85), B- (82), C+ (78), C (74), C- (70), D+ (66), D (62), D- (58), F (54)

Diversity, equity and inclusion responsibilities

The Grainger College of Engineering is committed to the creation of an anti-racist, inclusive community that welcomes diversity along a number of dimensions, including, but not limited to, race, ethnicity and national origins, gender and gender identity, sexuality, disability status, class, age, or religious beliefs. The College recognizes that we are learning together in the midst of the Black Lives Matter movement, that Black, Hispanic, and Indigenous voices and contributions have largely either been excluded from, or not recognized in, science and engineering, and that both overt racism and micro-aggressions threaten the well-being of our students and our university community.

The effectiveness of this course is dependent upon each of us to create a safe and encouraging learning environment that allows for the open exchange of ideas while also ensuring equitable opportunities and respect for all of us. Everyone is expected to help establish and maintain an environment where students, staff, and faculty can contribute without fear of personal ridicule, or intolerant or offensive language. If you witness or experience racism, discrimination, micro-aggressions, or other offensive behavior, you are encouraged to bring this to the attention of the course director if you feel comfortable. You can also report these behaviors directly through the Office of the Vice Chancellor for Diversity Equity and Inclusion ( Based on your report, members of the OVCDEI will follow up and reach out to students to make sure they have the support they need to be healthy and safe. If the reported behavior also violates university policy, staff in the Office for Student Conflict Resolution may respond as well and will take appropriate action.

Academic Integrity

All activities in this course, including documentation submitted for petition for an excused absence, are subject to the Academic Integrity rules as described in Article 1, Part 4, Academic Integrity, of the Student Code.
