Wave-particle delayed-choice experiments
Abstract: 波粒二象性是量子力学的一个基本特征，被著名物理学家费曼称为“包含了量子力学唯一的奥秘”。按照玻尔互补原理，一个量子系统同时具有波动性和粒子性，但这两种属性不能被同时观测到；系统表现出哪种属性...

Quantum Gate Operation in the Circuit-QED Lattice with Circulator Function
Abstract: We propose a scheme for a scalable quantum computing in the circuit-quantum electrodynamics(QED) architecture. In the Kagome lattice of qubits three qubits are connected to each other throu...

Quantum Journal Club: Entanglement of Light-Shift Compensated Atomic SpinWaves with Telecom Light
Abstract: Entanglement of a 795 nm light polarization qubit and an atomic Rb spin-wave qubit for a storage time of 0.1 s is observed by measuring the violation of Bell’s inequality (S ¼ 2:65 0:12)...

Quantum Journal Club: Electrically Driven Spin Resonance in Silicon Carbide Colo
Abstract: We demonstrate that the spin of optically addressable point defects can be coherently driven with acelectric fields. Based on magnetic-dipole forbidden spin transitions, this scheme enables...
