Fault-tolerant quantum computation with asymmetric Bacon-Shor codes
Peter Brooks, John Preskill
We develop a scheme for fault-tolerant quantum computation based on asymmetric Bacon-Shor codes, which works effectively against highly biased noise dominated by dephasing. We find…
Optimal Bacon-Shor codes
John Napp, John Preskill
We study the performance of Bacon-Shor codes, quantum subsystem codes which are well suited for applications to fault-tolerant quantum memory because the error syndrome can be extr…
Sufficient condition on noise correlations for scalable quantum computing
John Preskill
I study the effectiveness of fault-tolerant quantum computation against correlated Hamiltonian noise, and derive a sufficient condition for scalability. Arbitrarily long quantum co…
Quantum computing and the entanglement frontier
John Preskill
Quantum information science explores the frontier of highly complex quantum states, the "entanglement frontier." This study is motivated by the observation (widely believed but unp…
