Solid-state spin systems including nitrogen-vacancy (NV) centers in diamond constitute an
increasingly favored quantum sensing platform. However, present NV ensemble devices …

Quantum computers have made extraordinary progress over the past decade, and
significant milestones have been achieved along the path of pursuing universal fault-tolerant …

The nitrogen-vacancy (NV) center is a point defect in diamond with unique properties for use
in ultra-sensitive, high-resolution magnetometry. One of the most interesting and challenging …

Nonadiabatic geometric quantum computation (NGQC) and nonadiabatic holonomic
quantum computation (NHQC) have been proposed to reduce the run time of geometric …

We experimentally demonstrate fast and high-fidelity geometric control of a quantum system
with the brachistochrone method on hybrid spin registers in diamond. Based on the time …

The theory of angular momentum connects physical rotations and quantum spins together at
a fundamental level. Physical rotation of a quantum system will therefore affect fundamental …

Defects in solid-state materials provide an ideal, robust platform for quantum sensing. To
deliver maximum sensitivity, a large ensemble of noninteracting defects hosting quantum …

Inorganic hosts, such as SrB4O7 or certain nitrides, intrinsically stabilize Eu2+ even when
the dopant is an Eu3+‐based precursor and reducing conditions are not employed in the …

Quantum states can acquire a geometric phase called the Berry phase after adiabatically
traversing a closed loop, which depends on the path not the rate of motion. The Berry phase …

Spin squeezing has important applications in the field of quantum metrology and quantum
information processing. Here we propose that coherent population trap** is well suitable …
