We show that qubit decoherence due to zero-temperature energy relaxation can be almost completely suppressed by using the quantum uncollapsing (measurement reversal) procedure. To protect a qubit state, a partial quantum measurement moves it toward the ground state, where it is kept during the storage period, while the second partial measurement restores the initial state. This procedure prefer...

We have developed a measurement system based on a correlation method to characterize the nonlinearity of a detector's response over a large range of laser pulse energy. The system consists of an excimer-laser source, beam-shaping optics, a beam splitter, a monitor detector, a set of optical filters, and the detector under test. Detector nonlinearities as large as 10% or greater over an entire m...

A precision measurement by AMS of the positron fraction in primary cosmic rays in the energy range from 0.5 to 500 GeV based on 10.9 million positron and electron events is presented. This measurement extends the energy range of our previous observation and increases its precision. The new results show, for the first time, that above ∼200  GeV the positron fraction no longer exhibits an increas...

In measurement-based quantum computation, quantum algorithms are implemented via sequences of measurements. We describe a translationally invariant finite-range interaction on a one-dimensional qudit chain and prove that a single-shot measurement of the energy of an appropriate computational basis state with respect to this Hamiltonian provides the output of any quantum circuit. The required me...

Energy is one of the primary inputs in textile processing industries that have a significant impact on the cost of a cotton product. The energy cost-share is reported between 5-10% of the total production cost of woven cotton fabric in textile factories of developed countries. However, it is far higher in developing countries. This study aims to contribute to the understanding of energy use and...

We present the most precise inclusive measurement of the branching fraction and photon energy spectrum of b → sγ radiative decays up to date. The photon energy distribution is measured for E γ > 1.7 GeV. The measurement is performed by the Belle collaboration using 605 fb −1 of data recorded by the Belle detector at the KEKB collider.

چکیده نمایشگاه های جهانی یا اکسپو عنوانی ست که از سال 1851 میلادی در لندن توسط همسر ملکه انگلستان شکل گرفت ، هدف اولیه این نمایشگاه ها نمایش دستاورد های صنعتی بود، اما در طول 165 سال که این نمایشگاه های برگزار گردیدند ، رویکرد آنها تغییر کرده است . در هر دوره به یک شعار که در واقع دغدغه اصلی جهان، در آن زمان بوده است ، پاسخ داده شده و راه حل کشور های مختلف در مورد آن موضوع به نمایش گذارده شد...

seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
