Quantum error mitigation is a set of techniques aimed at reducing the effects of errors in quantum computers. Quantum devices are subject to environmental noise that degrades the quality of computations performed. While fault-tolerant quantum computing promises a solution to this problem, current quant...
Quantum hardware faces noise challenges that disrupt multiqubit entangled states. Quantum autoencoder circuits with a single qubit bottleneck have demonstrated the capability to correct errors in noisy entangled states. By introducing slightly more compl

Quantum error mitigation (QEM) presents a promising near-term approach to reducing errors when estimating expectation values in quantum computing. Here, we introduce QEM techniques tailored for quantum annealing, using zero-noise extrapolation (ZNE). We implement ZNE through zero-temperature and zero-...
An important measure of the development of quantum computing platforms has been the simulation of increasingly complex physical systems. Before fault-tolerant quantum computing, robust error-mitigation strategies were necessary to continue this growth. H
A research paper from IBM Quantum and UC Berkeley has delivered compelling evidence suggesting that today’s noisy, error-prone quantum computers will soon be able to solve truly useful problems that are beyond the reach of classical computation. In this video, co-authors and IBM Quantum resea...
