摘要：To solve problems of practical importance1,2, quantum computers probably need to incorporate quantum error correction, in which a logical qubit is redundantly encoded in many noisy physical qubits3, 4-5. The large physical-qubit overhead associated with error correction motivates the search for more hardware-efficient approaches6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17-18. Here, using a superconducting quantum circuit19, we realize a logical qubit memory formed from the concatenation of encod...

摘要：The Atlantic Meridional Overturning Circulation (AMOC), vital for northwards heat transport in the Atlantic Ocean, is projected to weaken owing to global warming1, with significant global climate impacts2. However, the extent of AMOC weakening is uncertain with wide variation across climate models1,3,4 and some statistical indicators suggesting an imminent collapse5. Here we show that the AMOC is resilient to extreme greenhouse gas and North Atlantic freshwater forcings across 34 climate model...
