A controlled-phase gate was demonstrated in superconducting Xmon transmon qubits with fidelity reaching 99.4%, relying on the adiabatic interaction between the |11〉 and |02〉 states. Here we explain the theoretical concepts behind this protocol, which achieves fast gate times with only σz control of the Hamiltonian, based on a theory of nonlinear mapping of state errors to a power spectral densi...

In the actual information management system, the query operation is the main part, and the query method is completed by the Select sentence in SQL language, so the efficiency of Select sentence directly influences the query efficiency, and the factors influencing query efficiency include query condition, view, index, link, operator and memory process. In the article, combining with examples, we...

We report simulation of nanostructured memristor device using piecewise linear and nonlinear window functions for RRAM and neuromorphic applications. The linear drift model of memristor has been exploited for the simulation purpose with the linear and non-linear window function as the mathematical and scripting basis. The results evidences that the piecewise linear window function can aptly sim...

The anchoring and adjustment heuristic has been shown to be a pervasive technique that people use in judgment, decision-making, and problem-solving tasks to reduce cognitive burden. However, reliance on the anchoring heuristic often leads to a systematic adjustment bias, in which people fail to make sufficient adjustments for a particular task. In a study involving 157 subjects from six univers...

Meal Example Consider a database storing nutritional information for single servings of different kinds of food in the following 4 relations: Meats, Vegetables, Fruits, and Beverages. All four relations have the same schema: name, cal, Vb6, Vc, fat, chol. Suppose that a meal consists of single servings of each of the four kinds of food. We are interested in finding meals that satisfy various nu...

The proportional-bandwidth and constant-bandwidth timefrequency signal decompositions of the wavelet, Gabor, and Wilson Manuscript received August 21, 1992; revised May 26, 1993. The Guest Editor coordinating the review of this paper and approving it for publication was Dr. Patrick Flandrin. This work was supported in part by the Sound Group of the computer-based Education Research Laboratory, ...

A controlled-phase gate was demonstrated in superconducting Xmon transmon qubits with fidelity reaching 99.4%, relying on the adiabatic interaction between the |11〉 and |02〉 states. We explain how adiabaticity is achieved even for fast gate times, based on a theory of non-linear mapping of state errors to a power spectral density and use of optimal window functions. With a solution given in the...

The global production and consumption of plastics have continued to increase. Plastics degrade slowly, causing persistent environmental pollution Developed waste plastic recycling methods are discussed in this report, with a focus on the dissolution/reprecipitation technique restore low-density polyethene (LDPE) wastes. Aspen HYSYS is used simulate LDPE. Turpentine/petroleum ether (TURP/PetE) c...
