CE Seminar by Dr. Sina Zeytinoğlu

Signal processing is an indispensable tool for the modern communication and control technologies. Yet, the concepts of signal processing have also led to a more fundamental understanding regarding the limits of efficient control protocols for physical devices. As such, the application of signal processing tools to quantum mechanical degrees of freedom not only promises the development of robust and useful quantum technologies but also a deeper understanding of the limitations of externally controlled quantum devices. In this talk, I will review recent developments in Quantum Signal Processing (QSP), a framework that I use to discuss the scaling of error-probability associated with a broad class of operations when implemented on a quantum mechanical processor. Specifically, I show that the error probability associated with a non-error-corrected protocol that evaluates a matrix polynomial f(A) only scales with the degree of the polynomial and not with the complexity of the signal matrix.
