Quantum Journal Club: Demonstration of a Coherent Electronic Spin Cluster in Diamond
内容： An obstacle for spin-based quantum sensors is magnetic noise due to proximal spins. However, a cluster of such spins can become an asset, if it can be controlled. Here, we polarize and readout ...

Quantum Journal Club: Hong-Ou-Mandel Interference between Two Deterministic Collective Excitations in an Atomic Ensemble
内容： We demonstrate deterministic generation of two distinct collective excitations in one atomic ensemble, and we realize the Hong-Ou-Mandel interference between them. Using Rydberg blockade we cre...

Quantum Journal Club: Extending the lifetime of a quantum bit with error correction in superconducting circuits
内容： Quantum error correction (QEC) can overcome the errors experienced by qubits1 and is therefore an essential component of a future quantum computer. To implement QEC, a qubit is redundantly enco...
