Kvantno računalništvo z atomi v svetlobnih pasteh

 

Opisali bomo, kako uporabimo posamezne atome cezija, ujete v mesta na 3D optični mreži, kot kvantne bite. Pojasnili bomo, kako ohladimo atome skoraj do teoretične meje, kako posegamo v sredino mreže, da bi spremenili kvantno stanje izbranega atoma, in kako urejamo atome po mreži. Ti postopki tvorijo fizično implementacijo Maxwellovega demona, ki je bil doslej le miselni eksperiment in ki osvetljuje globoko povezavo med entropijo in informacijo. 

 

Predavanje bo v angleščini.

Quantum computing with atoms trapped by light


I will describe how we use single cesium atoms, each trapped in a site of a 3D optical lattice, as quantum bits. I will explain how we cool the atoms almost as much as is theoretically possible, how we can effectively reach into the middle of the array to change the quantum state of any atom, and how we sort the atoms in the lattice.  Together these actions constitute a physical implementation of Maxwell's demon, previously only a thought experiment, which elucidates the deep connection between entropy and information.

 

 

Cordially invited!
