IT-Forum: What is quantum information theory?

Topic: 
What is quantum information theory?

Abstract / Description: 

Quantum information theory is the generalization of Shannon’s information theory to the realm of quantum mechanics. The basic questions are the same as for standard information theory: What is uncertainty? What is the best method for sending information through a noisy channel? The theory, however, is full of surprises. Random variables don’t commute. Correlation of the quantum variety increases channel capacities. Conditional entropy can be negative. Secrecy can be certified. I’ll give a brief introduction to quantum information theory, highlighting some of the key similarities and striking differences with Shannon theory.

 


The Information Theory Forum (IT-Forum) at Stanford ISL is an interdisciplinary academic forum which focuses on mathematical aspects of information processing. With a primary emphasis on information theory, we also welcome researchers from signal processing, learning and statistical inference, control and optimization to deliver talks at our forum. We also warmly welcome industrial affiliates in the above fields. The forum is typically held in Packard 202 every Friday at 1:00 pm during the academic year.

The Information Theory Forum is organized by graduate students Jiantao Jiao and Kartik Venkat. To suggest speakers, please contact any of the students.
