Decoherence of a Quantum Bit Circuit
... When the readout circuit measures the qubit, its backaction results in full qubit decoherence during the time needed to get the outcome, and even faster if the readout efficiency is below the quantum limit. In order to reduce decoherence, the readout circuit should thus be switched off when the qubi ...

Quantum orders in an exact soluble model
... In 1989, it was realized that FQH states, having a robust topological degeneracy, contain a completely new kind of order - topological order.[5] A whole new theory was developed to describe the topological orders in FQH liquids. (For a review, see Ref. [6].) The Landau’s theory was developed for cla ...

A “Garden of Forking Paths” – the Quantum
... paper is to sketch or review arguments in favor of some of the following basic claims. • In quantum mechanics, the “state” of a system – as conventionally defined – does not describe “what is” or “will be”; it does not have an ontological status. Rather it is a mathematical device enabling us to mak ...

Science as Representation: Flouting the Criteria
... Representations of the solar system by Copernicus and Tycho were such that each could refer to the other as showing the way things look from a different vantage point. Yet we must be clear that they were not constructing content of visual perspectives in the way of the painter Vasari. The latter con ...

Ultrafast geometric control of a single qubit using chirped pulses
... vector turns about the effective field vector Ω1 (about the x-axis); it stays in the y, z-plane all the time and points in the −z (z)-direction at the end of the pulse. Due to the second π-pulse, the population is transferred back to the initial state |0i (|1i); therefore the Bloch vector returns to ...
