2012年8月24日 · The oldest and simplest pulse sequence for dynamical decoupling is the CPMG sequence —a train of equidistant π-pulses around the same axis. In fig. 2, we compare the …

2015年8月24日 · In this work, we perform a theoretical and experimental analysis of the performance of several DD protocols, including standard CPMG and XY-based pulse …

2023年12月14日 · Dynamical decoupling (DD) is perhaps the simplest and least resource-intensive error-suppression strategy for improving quantum computer performance.

2017年9月25日 · In the experiment, CPMG was used to study the noise environment and KDD xy for storage. Here we show that the filter function of KDD xy is the same as that of CPMG.

2015年1月7日 · Therefore, a CPMG (Carr–Purcell–Meiboom–Gill) pulse sequence (RF 3 in Fig. 2) was used as a simple and effective method to measure the decoherence rate for 100 ms < τ < …

2021年4月22日 · CPMG and KDD x can reach a 1/e spin coherence lifetime of 2.68 ± 0.06 and 0.95 ± 0.03 h when τ = 20 ms, respectively. For storage of light, we measure the decay of the …

2011年11月30日 · Experimental relaxation times of the probe spin under the application of CPMG (squares) and KDD (circles) sequences. The black solid line represents a power law fitted to …

2024年3月6日 · We found that the recently introduced DD sequence KDD is remarkably robust and works for arbitrary initial conditions. It is much less susceptible to experimental …

Dynamical decoupling (DD) is a well-known technique to pro-tect idle qubits from decoherence error. However, the optimal approach to inserting DD sequences still remains unclear. In this …

ough optimized dynamical decoupling (DD). Cooling the sample down to 77 K suppresses longitudinal spin relaxation T1 effects and DD microwave pulses are used to increase the …
