Quantum control of decoherence in mesoscopic spin systems

量子力学在构建从计算到生物医学传感的新技术方面提供了一种尚未开发的资源。该项目将解决凝聚态系统中基于自旋的量子技术面临的最严重挑战：介观环境中波动磁场的消相干。通过量子控制和反馈方法，该项目将设计和演示新的技术来保持物质的量子相干态，这是用固有的可扩展构件构建大规模量子设备的关键一步。

Quantum mechanics provides a yet untapped resource in the construction of new technologies that span the range from computation to biomedical sensing. This project will tackle the most serious challenge facing quantum technologies based on spins in condensed matter systems: decoherence from fluctuating magnetic fields in the mesoscopic environment. Via quantum control and feedback methods this project will devise and demonstrate new techniques to 'keep alive' quantum coherent states of matter, a key step towards constructing large-scale quantum devices from inherently scalable building blocks.
