Autonomous quantum error correction beyond break-even and its metrological application
Zhongchu Ni, Ling Hu, Yanyan Cai +8
The ability to extend the lifetime of a logical qubit beyond that of the best physical qubit available within the same system, i.e., the break-even point, is a prerequisite for bui…

Antineutrinos produced from decays of neutrons cannot be in coherent superpositions of different mass eigenstates
Shi-Biao Zheng
The entire wavefunction of the antineutrino-proton-electron system, produced by the decay of a neutron is analyzed. It is proven that the antineutrino cannot be in coherent sup…
