Magic state distillation with permutation-invariant codes and a two-qubit example
Heather Leitch, Yingkai Ouyang
Magic states, by allowing non-Clifford gates through gate teleportation, are important building blocks of fault-tolerant quantum computation. Magic state distillation protocols aim…

The Cramér-Rao approach and global quantum estimation of bosonic states
Masahito Hayashi, Yingkai Ouyang
Quantum state estimation is a fundamental task in quantum information theory, where one estimates real parameters continuously embedded in a family of quantum states. In the theory…
