An architecture for two-qubit encoding in neutral ytterbium-171 atoms
Zhubing Jia, William Huie, Lintao Li +7
We present an architecture for encoding two qubits within the optical "clock" transition and nuclear spin-1/2 degree of freedom of neutral ytterbium-171 atoms. Inspired by recent h…
Control of an environmental spin defect beyond the coherence limit of a central spin
Alexander Ungar, Paola Cappellaro, Alexandre Cooper +1
Electronic spin defects in the environment of an optically-active spin can be used to increase the size and hence the performance of solid-state quantum registers, especially for a…
Repetitive readout and real-time control of nuclear spin qubits in Yb atoms
William Huie, Lintao Li, Neville Chen +4
We demonstrate high fidelity repetitive projective measurements of nuclear spin qubits in an array of neutral ytterbium-171 (Yb) atoms. We show that the qubit state can be…
Manipulating solid-state spin concentration through charge transport
Guoqing Wang, Changhao Li, Hao Tang +8
Solid-state spin defects are attractive candidates for developing quantum sensors and simulators. The spin and charge degrees of freedom in large defect ensembles are a promising p…
Self-consistent noise characterization of quantum devices
Won Kyu Calvin Sun, Paola Cappellaro
Characterizing and understanding the environment affecting quantum systems is critical to elucidate its physical properties and engineer better quantum devices. We develop an appro…
Improved entanglement detection with subspace witnesses
Won Kyu Calvin Sun, Alexandre Cooper, Paola Cappellaro
Entanglement, while being critical in many quantum applications, is difficult to characterize experimentally. While entanglement witnesses based on the fidelity to the target entan…
