Macromux: scalable postselection for high-threshold fault-tolerant quantum computation
Patrick Birchall, Jacob Bridgeman, Christopher Dawson +7
We introduce a new resource-efficient scheme for fault-tolerant quantum computation known as `macroscale multiplexing' (or simply `Macromux'), that utilizes scalable postselection…
Beating the Optimal Verification of Entangled States via Collective Strategies
Ye-Chao Liu, Jiangwei Shang
In the realm of quantum information processing, the efficient characterization of entangled states poses an overwhelming challenge, rendering the traditional methods including quan…
Prescriptive preparation and verification of nonstabilizer states
Jian Li, Ye-Chao Liu, Xiao-Xiao Chen +6
High-fidelity quantum state preparation is a central task in quantum information science. In practice, it is commonly guided either by full quantum state tomography, which becomes…
Verification of entangled states under noisy measurements
Lan Zhang, Yinfei Li, Ye-Chao Liu +1
Entanglement plays an indispensable role in numerous quantum information and quantum computation tasks, underscoring the need for efficiently verifying entangled states. In recent…
