Entangling Trapped Ions with a Low-Frequency Magnetic Field Gradient

Date:  Thursday,  January 25, 2018

Speaker:  David Allcock, NIST


Entangled states of trapped ions are typically generated using laser-induced spin-motion coupling. Spin-motion coupling with hyperfine qubits has also been demonstrated with microwave magnetic fields instead of lasers, thus eliminating photon scattering errors and offering potential benefits for scalability. These experiments have relied on either static magnetic field gradients or oscillating magnetic field gradients at GHz frequencies [1-4]. We present methods of spin-motion coupling using magnetic field


The UO Physics Dept. successfully wrapped up two large events in one week: the 2018 the Northwest Regional APS Conference for Undergraduate Women in Physics & the ‘Physics Slam’

When associate professor Stephanie Majewski of the physics department and her colleagues were planning the upcoming Northwest Regional Conference for Undergraduate Women in Physics, they were not overwhelmed by interest in the event. They were greatly overwhelmed, with well over 200 attendees flying in from colleges across the northwest.

“I don’t think I’ve ever seen that many female physicists together in one place.” Majewski said.

Majewski attributed the increase to a growing number of women entering STEM — science, technology, engineering and math — fields and an increasing


“I’m here for a reason” Benjamín Alemán’s research and journey to becoming a UO Physics professor featured in Oregon Quarterly

For UO Physics professor Benjamín Alemán, the science of the small, with its boundless potential to help humanity, is the grandest playground imaginable. He’s an expert at bending 21st-century miracle materials to his will. Take graphene, which is to today’s technology what plastic was to industry of the last century. Just one atom thick—a million times thinner than human hair—it’s 200 times stronger than steel, yet extraordinarily flexible.  Some might say that Alemán himself is just as strong and flexible; qualities that helped him on his challenging path to become a professor
