As part of the Saturday Physics Lecture Series, The Department of Physics Presents:听
"Quantum computing: what is it and how far along are we?"
Presented by: Daniel Slichter, NIST, 彩民宝典
2:30 p.m.
Abstract: Imagine if the act of looking at an object caused it to move 鈥� or imagine you had a pair of dice that always rolled doubles, but of different numbers each roll. These counterintuitive phenomena are commonplace in the realm of quantum mechanics, which describes systems that are generally very small, very cold, and/or very isolated from the rest of the world. Over the past 40 years, scientists have developed ideas for harnessing the strange features of quantum mechanics to build 鈥渜uantum computers鈥�, machines where information storage and computation is carried out by objects that behave quantum mechanically. A large-scale quantum computer would in principle be able to perform certain kinds of computations that would be impossible on even the largest classical (i.e. non-quantum) supercomputers. I will describe some of the basics of quantum mechanics and quantum computing, including why it is so technically challenging to build a 鈥渦seful鈥� large-scale quantum computer. I will also give some perspective on where things stand in the quest for quantum computers that will provide an advantage over existing computing technology.
The Saturday Physics Series听consists of five to seven scheduled talks oriented toward adults and high school students. Lectures occur on specific Saturdays afternoons throughout the school year, typically in Duane G1B30. Unless otherwise noted, lectures begin at 2:30 p.m., and usually last about one hour. Material is aimed at the level of high school juniors and seniors. The series is free, open to the public, and no reservations are required. Simply show up and enjoy the show!听
