Time domain analysis of dynamical switching in a josephson junction
2006 (English)In: Quantum Computing in Solid State Systems, Springer, 2006, 54-62 p.Chapter in book (Other academic)
A Josephson junction (JJ) when is connected to an external current source via a twisted pair with impedance Z, presents a probability distribution P of switching of the JJ, as a function of the current pulse from the source. Due to quantum effects and various noise sources, such as resistive leads at finite temperatures, this distribution will have a finite width. In a qubit system, such as the Quantronium, it is necessary that this width is small in order to clearly distinguish between different quantum states, and eventually realise the single shot measurement. © 2006 Springer Science+Business Media, Inc.
