Radiative properties of rubidium atoms trapped in solid neon and parahydrogen
David M. Lancaster, Ugne Dargyte, Sunil Upadhyay +1
It is known from ensemble measurements that rubidium atoms trapped in solid parahydrogen have favorable properties for quantum sensing of magnetic fields. To use a single rubidium…
Ultralong spin coherence times for rubidium atoms in solid parahydrogen via dynamical decoupling
Sunil Upadhyay, Ugne Dargyte, David Patterson +1
Coherence time is an essential parameter for quantum sensing, quantum information, and quantum computation. In this work, we demonstrate electron spin coherence times as long as 0.…
Spin coherence and optical properties of alkali-metal atoms in solid parahydrogen
Sunil Upadhyay, Ugne Dargyte, Vsevolod D. Dergachev +5
We present a joint experimental and theoretical study of spin coherence properties of 39K, 85Rb, 87Rb, and 133Cs atoms trapped in a solid parahydrogen matrix. We use optical pumpin…
Enhanced spin coherence of rubidium atoms in solid parahydrogen
Sunil Upadhyay, Ugne Dargyte, Robert P. Prater +5
We measure the transverse relaxation of the spin state of an ensemble of ground-state rubidium atoms trapped in solid parahydrogen at cryogenic temperatures. We find the spin depha…
