| 4 | One-step implementation of a multi-target-qubit controlled phase gate with cat-state qubits in circuit QED显示文摘We propose a single-step implementation of a muti-target-qubit controlled phase gate with one catstate qubit (cqubit) simultaneously controlling n — 1 target cqubits. The two logic states of a c.qubit are represented by two orthogonal cat states of a single cavity mode. In this proposal, the gate is implemented with n microwave cavities coupled to a superconducting transnion qutrit. Because the qutrit remains in the ground state during the gate operation, decoherence caused due to the qutrit5s energy relaxation and dephasing is greatly suppressed. The gate implementation is quite simple because only a single-stcp operation is needed and neither classical pulse nor measurement is required. Numerical simulations demonstrate that high-fidelity realization of a controlled phase gate with one cqubit simultaneously con trolling two targe t cqubits is feasible with present circuit QED technology. This proposal can be extended to a wide range of physical systems to realize the proposed gate, such as multiple microwave or optical cavities coupled to a natural or artificial three-level atom. | You-Ji Fan Zhen-Fei Zheng Yu Zhang Dao-Ming Lu Chui-Ping Yang | 2019 | Frontiers of physics2019，14，2： | 7 |
| 5 | Transparency and amplification in a hybrid system of the mechanical resonator and circuit QED显示文摘We theoretically study the transparency and amplification of a weak probe field applied to the cavity in hybrid systems formed by a driven superconducting circuit QED system and a mechanical resonator,or a driven optomechanical system and a superconducting qubit.We find that both the mechanical resonator and the superconducting qubit can result in the transparency to a weak probe field in such hybrid systems when a strong driving field is applied to the cavity.We also find that the weak probe field can be amplified in some parameter regimes.We further study the statistical properties of the output field via the degrees of second-order coherence.We find that the nonclassicality of the output field strongly depends on the system parameters.Our studies show that one can control single-photon transmission in the optomechanical system via a tunable artificial atom or in the circuit QED system via a mechanical resonator. | WANG Hui SUN HuiChen ZHANG Jing LIU YuXi | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，12： | 6 |
| 6 | Two mode photon bunching effect as witness of quantum criticality in circuit QED显示文摘We suggest a scheme to probe critical phenomena at a quantum phase transition (QPT) using the quantum correlation of two photonic modes simultaneously coupled to a critical system. As an experimentally accessible physical implementation,a circuit QED system is formed by a capacitively coupled Josephson junction qubit array interacting with one superconducting transmission line resonator (TLR). It realizes an Ising chain in the transverse field (ICTF) which interacts with the two magnetic modes propagating in the TLR. We demonstrate that in the vicinity of criticality the originally independent fields tend to display photon bunching effects due to their interaction with the ICTF. Thus,the occurrence of the QPT is reflected by the quantum characteristics of the photonic fields. | AI Qing1,WANG YingDan2,LONG GuiLu1,3 & SUN ChangPu4 1 Department of Physics,Tsinghua University,Beijing 100084,China 2 Department of Physics,University of Basel,Klingelbergstrasse 82,4056 Basel,Switzerland 3 Tsinghua National Laboratory for Information Science and Technology,Beijing 100084,China 4 Institute of Theoretical Physics,Chinese Academy of Sciences,Beijing 100080,China | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，12： | 6 |

| 8 | 1→N quantum controlled phase gate realized in a circuit QED system显示文摘We propose an effective method to realize the quantum phase gate of one qubit simultaneously controlling N qubits. We use the system in which the transmon qubits are capacitively coupled to a superconducting transmission line resonator driven by a strong microwave field. In our scheme, the phase gate can be realized in a time (nanosecond-scale) much shorter than decoherence time (microsecond-scale), and it is more immune to the 1/f charge noise and has longer dephasing time due to the favorable properties of the transmon qubits in the system. | GAO GuiLong CAI GenChang HUANG.ShouSheng TANG LongYing GU WenJing WANG MingFeng JIANG-NianQuan | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，8： | 4 |

| 10 | Preparation of genuine Yeo-Chua entangled state and teleportation of two-atom state via cavity QED显示文摘We first propose a scheme for preparing the genuine Yeo-Chua 4-qubit entangled state via cavity QED. Using the genuine Yeo-Chua atomic state, we further propose a cavity QED scheme for teleporting an arbitrary two-atom state. In two schemes the large-detuning is chosen and the necessary time is designed to be much shorter than Rydberg-atom’s lifespan. Both schemes share the distinct advantage that cavity decay and atom decay can be neglected. As for the interaction manipulation, our preparation scheme is more feasible than a recent similar one. Compared with the Yeo and Chua’s scheme, our teleportation scheme has significantly reduced the measuring difficulty. | ZHANG Wen 1 , LIU YiMin 2 , ZUO XueQin 1 & ZHANG ZhanJun 1* 1 School of Physics & Material Science, Anhui University, Hefei 230039, China 2 Department of Physics, Shaoguan University, Shaoguan 512005, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，12： | 3 |

| 12 | Generation and application of a controllable multi-atom entangled state显示文摘In this paper, we present a scheme to prepare a set of the multi-atom entangled states by the cavity quantum electrodynamics (QED) technology. The multi-atom entangled states have some particular entanglement properties.For example, the remaining reduced density matrices Pij still retain entanglement or disentanglement when any N-2 atoms of the N atoms are traced out, which can be chosen freely according to our need, and the relative entanglement strength of any pair of atoms (measured by the concurrence) can be arbitrarily adjusted. In addition, they may be completely symmetric under the exchange of any two atoms, and perform certain quantum information tasks, such as telecloning, teleportation, secret sharing and so on. | 黄燕霞 詹明生 | 2004 | Chinese Physics B2004，13，12： | 3 |

| 15 | A simple scheme to generate χ-type four-charge entangled states in circuit QED显示文摘We propose a simple scheme to generate χ-type four-charge entangled states by using SQUID-based charge qubits capacitively coupled to a transmission line resonator (TLR). The coupling between the superconducting qubit and the TLR can be effectively controlled by properly adjusting the control parameters of the charge qubit. The experimental feasibility of our scheme is also shown. | 高贵龙 宋付权 黄寿胜 王辉 袁先漳 王明锋 姜年权 | 2012 | Chinese Physics B2012，21，4： | 2 |
| 16 | Scheme for splitting quantum information via W states in cavity QED systems显示文摘Assisted by multipartite entanglement,Quantum information may be split so that the original qubit can be reconstructed if and only if the recipients cooperate.This paper proposes an experimentally feasible scheme for splitting quantum information via W-type entangled states in cavity QED systems,where three-level Rydberg atoms interact with nonresonant cavities.Since W-type states are used as the quantum channel and the cavities are only virtually excited,the scheme is easy to implement and robust against decoherence,and the dependence on the quality factor of the cavities is greatly reduced. | 于希梅 顾永建 马丽珍 周邦安 | 2008 | Chinese Physics B2008，17，2： | 2 |

| 18 | Robust generation of high-fidelity entangled states for multiple atoms显示文摘A scheme is presented for generating entangled states of multiple atoms in a cavity. In the scheme the atoms simultaneously interact with a cavity mode, with the first atom driven by two classical fields and the other atoms driven by a classical field. Our scheme is valid even if the cavity decay rate is larger than the effective coupling strength, which is important for experiment. The generation of entangled states is conditional on the detection of a photon decaying from the cavity and thus the fidelity of the entangled state is insensitive to the detection inefficiency. Furthermore, the scheme can be applied to the case with any number of atoms in principle. | 林丽华 | 2009 | Chinese Physics B2009，18，2： | 1 |
