INJEQT: Improved Magic-State Injection Protocol for Fault-Tolerant Quantum Extractor Architectures

Sayam Sethi, Sahil Khan, Aditi Awasthi +2

Near-term FTQC system designs are constrained by limited error budgets and largely sequential execution of non-Clifford gates. As a result, reducing the number of the most-error pr…

Dynamic local single-shot checks for toric codes

Yingjia Lin, Abhinav Anand, Kenneth R. Brown

Quantum error correction typically requires repeated syndrome extraction due to measurement noise, which results in substantial time overhead in fault-tolerant computation. Single-…

Unbiased observable estimation with approximate channels in fault-tolerant quantum computation

Dmitrii Khitrin, Kenneth R. Brown, Abhinav Anand

Unitary errors, such as those arising from fault-tolerant compilation of quantum algorithms, systematically bias observable estimates. Correcting this bias typically requires addit…
