Beyond the Purcell Effect: Controlling Pure Quantum Dephasing with Spin Noise Metasurfaces
Wenbo Sun, Shoaib Mahmud, Wei Zhang +4
One central theme in quantum photonics is tailoring the interactions between atoms/spins and their electromagnetic (EM) environments. Considerable effort has focused on engineering…
Probing near-field EM fluctuations in superparamagnetic CoFeB with NV quantum dephasometry
Shoaib Mahmud, Wei Zhang, Pronoy Das +3
Superparamagnetism in nanoscale magnetic layers is a critical property for a wide range of spintronic-based sensor and computing applications. While conventional magnetization meas…
Quantum Imaging of Photonic Spin Texture in an OAM Beam with NV Centers in Diamond
Shoaib Mahmud, Wei Zhang, Farid Kalhor +2
Photonic spin texture (PST), the spatial distribution of the spin angular momentum (SAM) of light, is connected to unique properties of light, such as optical skyrmions and topolog…
Optically induced static magnetic field in ensemble of nitrogen-vacancy centers in diamond
Farid Kalhor, Noah F. Opondo, Shoaib Mahmud +4
Generation of local magnetic field at the nanoscale is desired for many applications such as spin-qubit-based quantum memories. However, this is a challenge due to the slow decay o…
