Erasure surface code circuit without mid-circuit erasure checks

Margaret Pavlovich, Ivan Rojkov, Chen Wang +1

Quantum error correction (QEC) codes can correct twice as many erasure errors as Pauli errors. Because of this scaling advantage, there is significant interest in developing qubits…

Untangling QLDPC Codes with Biased Noise Ancilla

Runjiang Bi, Kathleen Chang, Shruti Puri

Remarkable technical progress has made high-rate, high-distance, quantum low-density parity-check codes (QLDPC) promising candidates for scalable quantum computing. However, it is…

Logical qubits with erasure conversion using metastable neutral atoms

Bichen Zhang, Genyue Liu, Guillaume Bornet +6

Implementing large-scale quantum algorithms with practical advantage will require fault-tolerance achieved through quantum error correction, but the associated overhead is prohibit…

Hardware-Efficient Erasure Qubits With Superconducting Transmon Qutrits

Bao-Jie Liu, Ying-Ying Wang, Yu-Xin Wang +3

Quantum error correction using erasure qubits offers higher fault-tolerant thresholds and improved scaling by converting dominant physical errors into detectable erasures. In super…

Dynamical error reshaping for dual-rail erasure qubits

Filippos Dakis, Shruti Puri, Sophia E. Economou +1

Erasure qubits -- qubits designed to have an error profile that is dominated by detectable leakage errors -- are a promising way to cut down the resources needed for quantum error…

Fold-transversal surface code cultivation

Kaavya Sahay, Pei-Kai Tsai, Kathleen Chang +4

Magic state cultivation is a state-of-the-art protocol to prepare ultra-high fidelity non-Clifford resource states for universal quantum computation. It offers a significant reduct…
