The accumulation of noise in quantum computers is the dominant issue stymieing the push of quantum algorithms beyond their classical counterparts. We do not expect to be able to afford the overhead required for quantum error correction in the next decade, so in the meantime we must rely on low-cost, unscalable error mitigation techniques to bring quantum computing to its full potential. This paper presents a new error mitigation technique based on quantum phase estimation that can also reduce… 
Virtual Distillation for Quantum Error Mitigation
TLDR
The effectiveness of virtual distillation is analyzed and it is found that it is governed in many regimes by the behaviour of this pure state (corresponding to the dominant eigenvector of $\rho$), and can improve the convergence of randomized quantum algorithms, even in the absence of device noise.
Error statistics and scalability of quantum error mitigation formulas
TLDR
Statistics principles are applied to quantum error mitigation and it is found that the error increases linearly with the gate number N before mitigation and sub-linearly O( ′Nγ) after mitigation, indicating that error mitigation can suppress the error by a larger factor in larger circuits.

Ground state preparation and energy estimation on early fault-tolerant quantum computers via quantum eigenvalue transformation of unitary matrices

A tool called quantum eigenvalue transformation of unitary matrices with real polynomials (QET-U), which uses a controlled Hamiltonian evolution as the input model, a single ancilla qubit and no multi-qubit control operations, and is thus suitable for early fault-tolerant quantum devices.
