# Open seminar - seminaria prowadzone przez doktorantów

### 1)

**Talk:**A few words about (quasi) probability in classical and quantum physics

**Date:**Tuesday 4, November 2014, 14.15

**Place:**room 311

**Speaker:**Kamil Kostrzewa

### 2)

**Talk:**Randomness in Quantum Theory

**Date:**Wednesday 19, November 2014, 15.15

**Place:**room 52

**Speaker:**Edgar A Aguilar Lozano

**Summary:**

Random numbers are an essential part of our everyday life. Obtaining true randomness seems to be impossible classically, where the world around us is deterministic. Furthermore, even if we had a small random seed, getting a longer string of random numbers algorithmically is proven to be impossible classically. These are tasks that concern us all: as scientists, we do Monte Carlo simulations assuming our numbers are random, and as bank customers, we do online transactions hoping enough randomness was used in making secret keys so nobody can steal our money. Luckily, quantum mechanics postulates that measurement outcomes are truly random, and provides us with a more powerful framework where we can perform expansion and amplification of random numbers. The talk will be focused on amplification, where given some random numbers which are correlated to other variables, we can process them to produce truly random bits uncorrelated to the rest of the world.

No prior knowledge of Quantum Mechanics or Bell's Theorem will be assumed.
