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…
Construction of a qudit using Schrodinger cat states and generation of hybrid entanglement between a discrete-variable qudit and a continuous-variable qudit
Qi-ping Su, Tong Liu, Yu Zhang +1
We show that a continuous-variable (CV) qudit can be constructed using quasiorthogonal cat states of a bosonic mode, when the phase encoded in each cat state is chosen appropriatel…
Single-step implementation of a hybrid controlled-NOT gate with one superconducting qubit simultaneously controlling multiple target cat-state qubits
Qi-Ping Su, Yu Zhang, Chui-Ping Yang
Hybrid quantum gates have recently drawn considerable attention. They play significant roles in connecting quantum information processors with qubits of different encoding and have…
Hybrid controlled-SUM gate with one superconducting qutrit and one cat-state qutrit and application in hybrid entangled state preparation
Qi-Ping Su, Yu Zhang, Liang Bin +1
Compared with a qubit, a qudit (i.e., -level or -state quantum system) provides a larger Hilbert space to store and process information. On the other hand, qudit-based hybrid…
Entanglement Dynamics in Anti--Symmetric Systems
Yu-Liang Fang, Jun-Long Zhao, Dong-Xu Chen +5
In the past years, many efforts have been made to study various noteworthy phenomena in both parity-time () and anti-parity-time () symmetric systems.…
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…
