Simple Mitigation Strategy for a Systematic Gate Error in IBMQ

چکیده
In this paper, we report the observation and characterisation of a systematic error in implementation U3 gates IBM quantum computers. By measuring effect gate for various rotation angles appears as an over-rotation, whose magnitude does not correlate with IBM’s cited errors calculated using Clifford randomized benchmarking. We propose simple mitigation procedure to limit effects error. show that strategy one can obtain improved results observed value CHSH inequality, measured cloud-based computer. This work highlights utility strategies short-depth circuits.

this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
A collusion mitigation scheme for reputation systems
Reputation management systems are in wide-spread use to regulate collaborations in cooperative systems. Collusion is one of the most destructive malicious behaviors in which colluders seek to affect a reputation management system in an unfair manner. Many reputation systems are vulnerable to collusion, and some model-specific mitigation methods are proposed to combat collusion. Detection of col...

Conventional leakage reduction techniques focus primarily on sub-threshold leakage mitigation, while neglecting the effect of gate leakage current. This work focuses on understanding gate leakage current and developing circuit techniques for total leakage minimization. We present an efficient technique for gate leakage of CMOS circuits. Input vector control and circuit reconfiguration technique...
متن کاملError and Error Mitigation in Low-Coverage Genome Assemblies
The recent release of twenty-two new genome sequences has dramatically increased the data available for mammalian comparative genomics, but twenty of these new sequences are currently limited to ∼2× coverage. Here we examine the extent of sequencing error in these 2× assemblies, and its potential impact in downstream analyses. By comparing 2× assemblies with high-quality sequences from the ENCO...
