Dynamical decoupling has been applied to nv center for eliminating the noise from environment and thus prolong the coherence time of electron spin 40, 54, 55. The decoherence time of a nv center at room temperature can be several milliseconds [ 5, 6 ], which enables the implementation of quantum operation and quantum. Together, dephasing and relaxation destroy coherence at a total rate that is a sum of the two, summarized in the equation 1/t2 = 1/td+ 1/(2t1).

The coherence of the nv − center ensemble in diamond primarily depends on the density of the paramagnetic impurities. Coherence time t 2 decreases. Our results showed that the coherence times of nv centers declined rapidly with the depth reduction in the last about 22 nm before they finally disappeared, which revealed a critical.
One Of The Biggest Challenges To Implement Quantum Protocols And Quantum Information Processing (Qip) Is Achieving Long Coherence Times, Usually Requiring Systems At.
We systematically investigate the coherence properties of nv center ensemble at temperatures ranging from 300 k to 600 k in this paper. We are utilizing the nv center as a. Uniform distribution of nv centers;
300 Ppb Coherence Time T 2:
Hence, coherent control of nv center spins is achieved at room temperature, and the coherence time ${t}_{2}$ can be reached to around $17.1\text{ }\text{. These centers are nanoscale spin qubits possessing long spin coherence time and high magnetic field sensitivity even at ambient conditions. The decoherence time of a certain nv center spin depends on the bath spin configurations around it.

Two nv center densities available; We discuss the time constants for dephasing.
