Error estimation in current noisy quantum computers
Quantum Information Processing, 2023 Abstract One of the main important features of the noisy intermediate-scale quantum(NISQ) era is the correct evaluation and consideration of errors. In this paper, we analyze the main sources of errors in current (IBM) quantum computers and we present a useful tool (TED-qc) designed to facilitate the total error probability expected for any ...

Improved current-regulated delta modulator for reducing switching frequency and low-frequency current error in permanent magnet brushless AC drives [PDF]
, 2005 The conventional current-regulated delta modulator (CRDM) results in a high current ripple and a high switching frequency at low rotational speeds, and in low-frequency current harmonics, including a fundamental current error, at high rotational speeds ...

Systematic Errors in Current Quantum State Tomography Tools [PDF]
Physical Review Letters, 2015 Common tools for obtaining physical density matrices in experimental quantum state tomography are shown here to cause systematic errors. For example, using maximum likelihood or least squares optimization for state reconstruction, we observe a systematic underestimation of the fidelity and an overestimation of entanglement.

Constraining f(R) theories with the energy conditions [PDF]
, 2006 A new method to constrain gravitational theories depending on the Ricci scalar is presented. It is based on the weak energy condition and yields limits on the parameters of a given theory through the current values of the derivatives of the scale factor ...

Current and voltage based bit errors and their combined mitigation for the Kirchhoff-law-Johnson-noise secure key exchange [PDF]
, 2013 We classify and analyze bit errors in the current measurement mode of the Kirchhoff-law-Johnson-noise (KLJN) key distribution. The error probability decays exponentially with increasing bit exchange period and fixed bandwidth, which is similar to the ...

Effective control of the error in a direct measurement of core-loss power [PDF]
, 1995 Accuracy of a direct measurement of core-loss power is severely limited in many applications by the extra phase shift between the measured voltage and current.

NURSING ERRORS: A STUDY OF THE CURRENT LITERATURE [PDF]
Texto & Contexto - Enfermagem, 2017 ABSTRACT Objective: to characterize what the current literature states about nursing errors, with a specific review on how these errors are communicated to society by the media. Method: a qualitative documental research, characterized as an integrative literature review, performed using four databases and guided by a formal protocol, in the period from

Error processing in current and former cocaine users [PDF]
Brain Imaging and Behavior, 2013 Deficits in response inhibition and error processing can result in maladaptive behavior, including failure to use past mistakes to inform present decisions. A specific deficit in inhibiting a prepotent response represents one aspect of impulsivity and is a prominent feature of addictive behaviors in general, including cocaine abuse/dependence.
