Robustness-optimized quantum error correction
David Layden, Louisa Ruixue Huang, Paola Cappellaro
Quantum error correction codes are usually designed to correct errors regardless of their physical origins. In large-scale devices, this is an essential feature. In smaller-scale d…
Repetitive Readout Enhanced by Machine Learning
Genyue Liu, Mo Chen, Yi-Xiang Liu +2
Single-shot readout is a key component for scalable quantum information processing. However, many solid-state qubits with favorable properties lack the single-shot readout capabili…
Efficient quantum error correction of dephasing induced by a common fluctuator
David Layden, Mo Chen, Paola Cappellaro
Quantum error correction is expected to be essential in large-scale quantum technologies. However, the substantial overhead of qubits it requires is thought to greatly limit its ut…
Ancilla-free quantum error correction codes for quantum metrology
David Layden, Sisi Zhou, Paola Cappellaro +1
Quantum error correction has recently emerged as a tool to enhance quantum sensing under Markovian noise. It works by correcting errors in a sensor while letting a signal imprint o…
