摘      要：Qubit,as the basic unit of quantum operations,has at least two quantum states for *** itself has no superimposable quantum states,but after injecting N atoms,the resulted nitrogenvacancy centers form excellent-performance *** the same purpose,we can also obtain qubits by modifying the matrix without effective quantum ***-1({Cu_(3)(BTC)_(2)(H_(2)O)_(3)},BTC=1,3,5-benzene-tricarboxylate)with S=0 ground state is electron paramagnetic resonance(EPR)silent,so it is not a qubit ***,the spontaneously hydrolyzed HKUST-1 produces dilute uncoupled Cu^(Ⅱ)ions with S=1/*** this paper,we utilized the hydrolysis products of HKUST-1 to obtain qubits and assembled a core-shell structural HKUST-1@ZIF-8 by ZIF-8({Zn(mim)_(2)},mim=2-methylimidazole)coated over HKUST-1 for controlling the *** experimental results clearly show that the qubits come from hydrolyzed Cu^(Ⅱ)***,the dilute uncoupled Cu^(Ⅱ)ions in this assembly can effectively reduce the decoherence of *** EPR studies show that the T_(2) of this compound is 1067 ns at 10 K.
