Researchers in the Netherlands designed and fabricated the fully engineerable, device with operational wavelength of 1550 nanometers to enable the system to work in the low-loss telecommunication band wavelength. The system’s optical and mechanical resonances are fully artificial. They were able to show that the memory has a satisfactory lifetime and coherence while successfully creating the superposition state. In future studies, they plan to gain a better understanding of why the de-phasing of a quantum state, to avoid having such a short coherence, understand the underlying microscopic mechanisms, and increase the overall efficiency of the memory. The research findings have applications in quantum network, connecting quantum systems, and quantum computing…read more. TECHNICAL ARTICLE
