# qubit: the flip-flop quantum processor, the begin

AA << introduce the flip-flop qubit, a combination of the electron-nuclear spin states of a phosphorus donor that can be controlled by microwave electric fields >>

<< to encode quantum information in the electron-nuclear spin states of 31P [phosphorus] donors in silicon, and to realize fast, high-fidelity, electrically driven universal quantum gates >>

<< a credible pathway to the construction of a large-scale quantum processor, where atomic-size spin qubits are integrated with silicon nanoelectronic devices, in a platform that does not require atomic-scale precision in the qubit placement [..] and, with realistic assumptions on noise and imperfections, are predicted to achieve error rates compatible with fault-tolerant quantum error correction >>

https://www.nature.com/articles/s41467-017-00378-x

<< a new way to define a 'spin qubit' that uses both the electron and the nucleus of the atom. Crucially, this new qubit can be controlled using electric signals, instead of magnetic ones. Electric signals are significantly easier to distribute and localise within an electronic chip >>

# behav: even more devious than previously thought

<< The common cuckoo, notorious for evading parental duty by hiding her eggs in the nests of other brooding birds, is even more devious than previously thought >>

<< Parasites evolve not only to evade host defences but also to manipulate host behaviour >>

AA << test whether a brood parasitic cuckoo manipulates host perception of predation risk using an acoustic signal—a hawk-like call—that might misdirect host defences and thereby reduce the chance that hosts detect parasitism >>

AA << propose that the female cuckoo chuckle call tricks the hosts into responding vigilantly as if they were exposed to danger from a hawk, instead of from a cuckoo. This would divert host attention from clutch protection to self-protection, and so reduce the chance of the hosts detecting that they have been parasitized >>

<< While the investigation of decision-making biases has a long history in economics and psychology, learning biases have been much less systematically investigated. This is surprising as most of the choices we deal with in everyday life are recurrent, thus allowing learning to occur and therefore influencing future decision-making >>

AA << show that the valence of an outcome biases both factual and counterfactual learning. When considering factual and counterfactual learning together, it appears that people tend to preferentially take into account information that confirms their current choice >>
