Quantum Computation as a Dynamical Process
In this paper, we discuss the dynamical issues of quantum computation. We demonstrate that fast wave function oscillations can affect the performance of Shor’s quantum algorithm by destroying required quantum interference. We also show that this destructive effect can be routinely avoided by using resonant-pulse techniques. We discuss the dynamics of resonant pulse implementations of quantum lo...
متن کاملDynamical localization and repeated measurements in a quantum computation process.
We study numerically the effects of measurements on dynamical localization in the kicked rotator model simulated on a quantum computer. Contrary to the previous studies, which showed that measurements induce a diffusive probability spreading, our results demonstrate that localization can be preserved for repeated single-qubit measurements. We detect a transition from a localized to a delocalize...
متن کاملQuantum Computation Computation Is a Physical Process !
As computers become faster they must become smaller because of the niteness of the speed of light. The history of computer technology has involved a sequence of changes from one type of physical realisation to another-from gears to relays to valves to transistors to integrated circuits and so on. Quantum mechanics is already important in the design of microelectronic components. Soon it will be...
متن کاملReversible computation as a model for the quantum measurement process∗
The connection between information and physical entropy, in particular the entropy increase during computational steps corresponding to an irreversible loss of information—deletion or other many-to-one operations—has raised considerable attention in the physics community [1]. Figure 1 [2] depicts a flow diagram, illustrating the difference between one-toone, many-to-one and one-to-many computat...
متن کاملTeleportation as a quantum computation
Among the many exciting new applications of quantum physics in the realm of computation and information theory, I am particularly fond of quantum cryptography, quantum computing and quantum teleportation [5]. Quantum cryptography allows for the confidential transmission of classical information under the nose of an eavesdropper, regardless of her computing power or technological sophistication ...
