Control of Spin Coherence and Quantum Sensing in Diamond,ry sensitive to environmental noises. Quantum sensing utilizes this character to realize high sensitivity. Therefore, control of coherence is a central issue in quantum technology. In this chapter, we mainly present recent our researches about the extension of coherence times of NV centers in diamon

Collective Effects in Hybrid Quantum Systems,These hybrid quantum systems have been extensively investigated both experimentally and theoretically with an archetypical example being ensembles of atoms coupled to one form of electromagnetic field. Typically these composite systems have been operated in the low excitation regime where the overal

Superconducting quantum interference devices (SQUIDs) and superconducting flux qubits can be used as a sensitive magnetic field sensor to detect local electron spin resonance (ESR). These types of sensor are characterized by good sensitivity and high spatial resolution for electron spins

They may find application as a spin-qubit coupled with microwave photons or for engineering of helical states that are an important component for realization of Majorana Fermions in combination with superconductivity. In this chapter, we describe magnetoresistance measureme

Photonic Quantum Interfaces Among Different Physical Systems,ittle or no decoherence due to extremely low thermal noise even at room temperature; and they are the fastest information carriers available. As such, photons are perfect candidates for interfacing qubits in different physical systems with different operating frequencies (e.g., photons, ions, atoms,
