CS 860: Quantum Lower Bounds (Spring 2020)

Course Description

This course is about what we cannot do with computers we do not have. We will explore different methods for proving the nonexistence of quantum algorithms, within concrete computational models where such nonexistence theorems can be formally proved. We will start with the "big three" lower bound techniques (hybrid method, polynomial method, and adversary method), and subsequently explore other topics such as dual polynomials, negative- and multiplicative-weight adversaries, gamma 2 norms (filtered and approximate), "ironic" lower bounds, quantum information cost, etc.

Logistics

Due to the COVID-19 situation, this course will take place exclusively online in asynchronous form (meaning there will be no live lectures). Here are some logistical details.

Schedule

In lieu of live lectures, regular course notes and/or readings will be posted here.
