Phys.org June 15, 2020 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.
