Dephasing and leakage dynamics of noisy Majorana-based qubits: Topological versus Andreev [PDF]
, 2019 Topological quantum computation encodes quantum information nonlocally by nucleating non-Abelian anyons separated by distances L, typically spanning the qubit device size. This nonlocality renders topological qubits exponentially immune to dephasing from

Leakage is prohibited: memory protection extensions protected address space randomization [PDF]
Tsinghua Science and Technology, 2019 Code reuse attacks pose a severe threat to modern applications. These attacks reuse existing code segments of vulnerable applications as attack payloads and hijack the control flow of a victim application. With high code entropy and a relatively low performance overhead, Address Space Layout Randomization (ASLR) has become the most widely explored ...
