If noisy-intermediate-scale-quantum-era quantum computers are to perform useful tasks,
they will need to employ powerful error mitigation techniques. Quasiprobability methods can …

Quantum error mitigation (QEM) is vital for noisy intermediate-scale quantum (NISQ)
devices. While most conventional QEM schemes assume discrete gate-based circuits with …

Using near-term quantum computers to achieve a quantum advantage requires efficient
strategies to improve the performance of the noisy quantum devices presently available. We …

Quantum computers are poised to radically outperform their classical counterparts by

Autonomous quantum error correction (AQEC) protects logical qubits by engineered
dissipation and thus circumvents the necessity of frequent, error-prone measurement …

Achieving near-term quantum advantage will require accurate estimation of quantum
observables despite significant hardware noise. For this purpose, we propose a novel …

We propose a general framework for quantum error mitigation that combines and
generalizes two techniques: probabilistic error cancellation (PEC) and zero-noise …

Medium-scale quantum devices that integrate about hundreds of physical qubits are likely to
be developed in the near future. However, these devices will lack the resources for realizing …

Quantum error-mitigation techniques can reduce noise on current quantum hardware
without the need for fault-tolerant quantum error correction. For instance, the …

Quantum error mitigation has been proposed as a means to combat unwanted and
unavoidable errors in near-term quantum computing without the heavy resource overheads …
