Quantum state discrimination in a PT-symmetric system
Dong-Xu Chen, Yu Zhang, Jun-Long Zhao +4
Nonorthogonal quantum state discrimination (QSD) plays an important role in quantum information and quantum communication. In addition, compared to Hermitian quantum systems, parit…
Experimental investigation of wave-particle duality relations in asymmetric beam interference
Dong-Xu Chen, Yu Zhang, Jun-Long Zhao +4
Wave-particle duality relations are fundamental for quantum physics. Previous experimental studies of duality relations mainly focus on the quadratic relation , based…
Efficient scheme for realizing a multiplex-controlled phase gate with photonic qubits in circuit quantum electrodynamics
Qi-Ping Su, Yu Zhang, Liang Bin +1
We propose an efficient scheme to implement a multiplex-controlled phase gate with multiple photonic qubits simultaneously controlling one target photonic qubit based on circuit qu…
Experimental demonstration of coherence flow in - and anti--symmetric systems
Yu-Liang Fang, Jun-Long Zhao, Yu Zhang +5
Non-Hermitian parity-time () and anti-parity-time ()-symmetric systems exhibit novel quantum properties and have attracted increasing interest. Althoug…
Generation of quantum entangled states of multiple groups of qubits distributed in multiple cavities
Tong Liu, Qi-Ping Su, Yu Zhang +2
Provided that cavities are initially in a Greenberger-Horne-Zeilinger (GHZ) entangled state, we show that GHZ states of N-group qubits distributed in N cavities can be created via…
Transferring entangled states of photonic cat-state qubits in circuit QED
Tong Liu, Zhen-Fei Zheng, Yu Zhang +2
We propose a method for transferring quantum entangled states of two photonic cat-state qubits (cqubits) from two microwave cavities to the other two microwave cavities. This propo…
