Syndrome-Resolved Decoding of Qubit Readout Errors
Han Zheng, Vladimir Pešić, Nikolay Gusarov +7
Readout errors in superconducting qubits include incorrect state assignment, bit flips within the computational subspace, and leakage to non-computational states. These errors requ…
Logical computation with canonical lifted product codes
Han Zheng, Guo Zheng, Liang Jiang +1
High-rate quantum low-density parity-check (qLDPC) codes encode many logical qubits with low physical-qubit overhead, but realizing efficient fault-tolerant computation on such den…
Learning Midcircuit Measurement Backaction from Three Repeated Measurements
Chia-Tung Chu, Su-un Lee, Han Zheng +4
Accurate modeling of midcircuit measurements (MCMs) is essential for dynamic-circuit operations such as syndrome extraction, measurement-based reset, and the separation of state-pr…
Efficient learning of logical noise from syndrome data
Han Zheng, Chia-Tung Chu, Senrui Chen +4
Characterizing errors in quantum circuits is essential for device calibration, yet detecting rare error events requires a large number of samples. This challenge is particularly se…
Dark spin-cats as biased qubits
Andreas Kruckenhauser, Ming Yuan, Han Zheng +8
We present a biased atomic qubit, universally implementable across all atomic platforms, encoded as a `spin-cat' within ground state Zeeman levels. The key characteristic of our co…
Coherent control of a few-channel hole type gatemon qubit
Han Zheng, Luk Yi Cheung, Nikunj Sangwan +9
Gatemon qubits are the electrically tunable cousins of superconducting transmon qubits. In this work, we demonstrate the full coherent control of a gatemon qubit based on hole carr…
