Fault-Tolerant Quantum Dynamical Decoupling [PDF]

, 2005
Dynamical decoupling pulse sequences have been used to extend coherence times in quantum systems ever since the discovery of the spin-echo effect. Here we introduce a method of recursively concatenated dynamical decoupling pulses, designed to overcome ...

Rational Design of Ni3+‐Rich Nickel Nitride Enables Paired Electrooxidation of Sterol and Hydrogen Evolution in a Flow Electrolyzer

Advanced Science, EarlyView.
The rational design of Ni3+‐rich active sites on nickel nitride nanosheets via Pd‐induced electronic modulation, which was employed in the electrooxidation of sterol coupled with H2 production in a large flow electrolyzer. This work offers a novel strategy for the design and synthesis of highly efficient electrocatalysts and electrolyzers toward the ...
