Minutes-scale Schr{\'o}dinger-cat state of spin-5/2 atoms

Autor: Yang, Y. A., Luo, W. -T., Zhang, J. -L., Wang, S. -Z., Zou, Chang-Ling, Xia, T., Lu, Z. -T.

Quantum metrology with nonclassical states offers a promising route to improved precision in physical measurements. The quantum effects of Schr{\"o}dinger-cat superpositions or entanglements allow measurement uncertainties to reach below the standard

We describe and benchmark a new quantum charge-coupled device (QCCD) trapped-ion quantum computer based on a linear trap with periodic boundary conditions, which resembles a race track. The new system successfully incorporates several technologies cr

Measurement of the Electric Dipole Moment of $^{171}$Yb Atoms in an Optical Dipole Trap

Autor: Zheng, T. A., Yang, Y. A., Wang, S. -Z., Singh, J. T., Xiong, Z. -X., Xia, T., Lu, Z. -T.

The permanent electric dipole moment (EDM) of the $^{171}$Yb $(I=1/2)$ atom is measured with atoms held in an optical dipole trap (ODT). By enabling a cycling transition that is simultaneously spin-selective and spin-preserving, a quantum non-demolit

Deep Learning-based Assessment of Hepatic Steatosis on chest CT

Autor: Zhang, Zhongyi, Weiss, Jakob, Taron, Jana, Zeleznik, Roman, Lu, Michael T., Aerts, Hugo J. W. L.

Purpose: Automatic methods are required for the early detection of hepatic steatosis to avoid progression to cirrhosis and cancer. Here, we developed a fully automated deep learning pipeline to quantify hepatic steatosis on non-contrast enhanced ches
