Zapraszamy na seminarium 14.06.2022

Dear All,

 

we have the pleasure to invite you to the Particle Theory Seminar on Tuesday, 

June 14 at 12:15, which will be given by

 

Karol Życzkowski (IFT)

 

entitled

 

“Thirty-six quantum officers of Euler: quantum solution of a classically impossible problem”

 

Abstract:  Negative solution to the famous problem of 36 officers of Euler implies that there are no two orthogonal Latin squares of order six. We show that the problem has a solution, provided the ranks and the units of each officer can be entangled,  and construct quantum orthogonal Latin squares of this size. The solution can be visualized on a chessboard of size six, which shows that 36 officers are split in nine groups, each containing of four entangled states.  This design provides a unique example of extremal quantum state and allows us to construct an original quantum error detection code.

 

The seminar will be in a hybrid mode, local people are invited to meet in the seminar room D-2-02.
