Quantum computers can exploit a Hilbert space whose dimension increases exponentially with the number of qubits. In experiment, quantum supremacy has recently been achieved by the Google team by using a noisy intermediate-scale quantum (NISQ) device with over 50 qubits. However, the question of what can be implemented on NISQ devices is still not fully explored, and discovering useful tasks for such devices is a topic of considerable interest. Hybrid quantum-classical algorithms are regarded as… Expand
Variational Quantum Algorithms
An overview of the field of Variational Quantum Algorithms is presented and strategies to overcome their challenges as well as the exciting prospects for using them as a means to obtain quantum advantage are discussed. Expand
Noise-Induced Barren Plateaus in Variational Quantum Algorithms
This work rigorously proves a serious limitation for noisy VQAs, in that the noise causes the training landscape to have a barren plateau (i.e., vanishing gradient), and implements numerical heuristics that confirm the NIBP phenomenon for a realistic hardware noise model. Expand
Exponential Error Suppression for Near-Term Quantum Devices
As quantum computers mature, quantum error correcting codes (QECs) will be adopted in order to suppress errors to any desired level $\mathcal{E}$ at a cost in qubit-count $n$ that is merelyExpand
Quantum error mitigation for fault-tolerant quantum computing
This work shows QEM can compensate dominant errors in FTQC without increasing the number of qubits, which will dramatically alleviate required overheads ofFTQC for achieving a high-accuracy quantum computing. Expand

Error mitigation by training with fermionic linear optics
Noisy intermediate-scale quantum (NISQ) computers could solve quantum-mechanical simulation problems that are beyond the capabilities of classical computers. However, NISQ devices experienceExpand
Sensor-assisted fault mitigation in quantum computation
We propose a method to assist fault mitigation in quantum computation through the use of sensors co-located near physical qubits. Specifically, we consider using transition edge sensors colocated onExpand
