The symmetry of the space where a spin qubit resides plays an essential role in the
manipulation of quantum entanglement, which governs the performance of quantum …

Quantum sensing exploits the strong sensitivity of quantum systems to measure small
external signals. The nitrogen-vacancy (NV) center in diamond is one of the most promising …

Robust measurement of single quantum bits plays a key role in the realization of quantum

We propose a mechanism of coherent coupling between distant spin qubits interacting
dipolarly with a ferromagnet. We derive an effective two-spin interaction Hamiltonian and …

Entanglements serve as a resource for any quantum information system and are
deterministically generated or swapped by a joint measurement called complete Bell state …

Nitrogen–vacancy (NV) center in diamond is one of the most promising candidates to
implement room temperature quantum computing. In this review, we briefly discuss the …

A controlled qubit in a rotating frame opens new opportunities to probe fundamental
quantum physics, such as geometric phases in physically rotating frames, and can …

We present measurements of the Berry Phase in a single solid-state spin qubit associated
with the nitrogen-vacancy center in diamond. Our results demonstrate the remarkable …

Geometric nature, which appears in photon polarization, also appears in spin polarization
under a zero magnetic field. These two polarized quanta, one travelling in vacuum and the …

Hybrid systems of electron and nuclear spins are a fundamental building block for scalable
quantum information processing. Here we propose a fast and high-fidelity control scheme …
