We propose a simplified version of the Kitaev’s surface code in which error correction requires only three-qubit parity measurements for Pauli operators XXX and ZZZ. The new code belongs to the class of subsystem stabilizer codes. It inherits many favorable properties of the standard surface code such as encoding of multiple logical qubits on a planar lattice with punctured holes, efficient dec...

this paper develops an analysis of budget deficit financing in termsof a crowding out or crowding in effect on the activity of the privatesector for the economies of iran and algeria as two mena countries,(because of its economic structures (dependence on oil revenue)) duringthe period 1970-2012 by using cointegration and vector errorcorrection approaches. the analysis confirms the existence of...

Knill demonstrated a fault-tolerant quantum computation scheme based on concatenated error-detecting codes and postselection with a simulated error threshold of 3% over the depolarizing channel. We show how to use Knill’s postselection scheme in a practical two-dimensional quantum architecture that we designed with the goal to optimize the error correction properties, while satisfying important...

this study investigated the dynamic relationship between money, prices and output in a multivariate structure of casualty analysis in iran for the two period of 1969 to 2012 (entire period) and 1989 to 2012 (sub-period). this statistical framework has been projected for situations where causal links may have changed over the sample period. results of a three-variable vector error correction mod...

among the food products, grains play an important role in the consumption patterns of people, especially in the developing countries. since iran's main source of public dietary energy comes directly from grains, investigating and identifying the determinants of import of these products can be an important step towards food security. most experimental studies consider import of grains as only a ...

This paper uses the semiparametric error correction model (Li andWooldridge, 2002) and investigates the dynamics of wage, employment and labor efficiency after introducing five-day work week to the Korean labor market. Efficient working hour function is obtained by nonparametric method (polynomial approximation) and the dynamics are investigated using impulse response analysis. Average derivati...

The imbalances between investment financing and domestic savings in terms of providing sufficient capital are an obstacle to implementing economic development Indonesia. Therefore, the flow foreign is indispensable, one which by portfolio order increase market liquidity as a source development. This study aims analyze response influence gross product variables, inflation, exchange rates, intere...

We consider structural vector error correction models (VECMs) in which permanent shocks are partially identified with a set of long-run restrictions, and fully identified with an additional set of short-run restrictions. An identification method with a combination of short-run and long-run restrictions has been studied in the vector autoregressive models literature, but not thoroughly applied t...
