A hybrid quantum interferometer bridging Hong-Ou-Mandel and N00N-state interference
Zi-Qi Zeng, Samuel Corona-Aquino, Tao Xie +13
Hong-Ou-Mandel (HOM) interference offers robustness in high-noise environments due to its phase-insensitive nature, while N00N-state interference provides enhanced phase sensitivit…
Single-Period Floquet Control of Bosonic Codes with Quantum Lattice Gates
Tangyou Huang, Lei Du, Lingzhen Guo
Bosonic codes constitute a promising route to fault-tolerant quantum computing. Existing Floquet protocols enable analytical construction of bosonic codes but typically rely on slo…
Cancelling second order frequency shifts in Ge hole spin qubits via bichromatic control
Xiangjun Tan, Zhanning Wang, Wenkai Bai +1
Germanium quantum dot hole spin qubits are compatible with fully electrical control and are progressing toward multi-qubit operations. However, their coherence is limited by charge…
Additivity of disjoint interval entanglement in quasiparticle excited states
Zhouhao Guo, Jiaju Zhang
We investigate mixed-state entanglement measures, namely reflected entropy, mutual information and logarithmic negativity, for two disjoint intervals in one-dimensional systems exc…

Zhi-Jie Liu, Hao-Nan Qiang, Jie Zhou +2
The state, a canonical representative of multipartite quantum entanglement, plays a crucial role in quantum information science due to its robust entanglement properties. Quant…
Efficient computation of average subsystem Bures distance between fermionic Gaussian states
Zhouhao Guo, M. A. Rajabpour, Jiaju Zhang
The average subsystem trace distance has been proposed as an indicator of quantum many-body chaos and integrability. However, evaluating it presents two main difficulties: high com…

We propose a teleportation protocol that enables perfect transmission of a qubit using a partially entangled two-qutrit quantum channel. Within our scheme, we analyze the relations…
Giant atom with disorders: Effects from imperfect couplings
Muming Han, Lingzhen Guo
The study of giant atoms goes beyond the local interaction paradigm in the conventional quantum optics, and predicts novel phenomena, such as oscillating bound states in the contin…
Chirality, Nonreciprocity and Symmetries for a Giant Atom
Luting Xu, Lingzhen Guo
Chiral and nonreciprocal quantum devices are crucial for signal routing and processing in a quantum network. In this work, we study the chirality and nonreciprocity of a giant atom…
Optical interference by amplitude measurement
Yunxiao Zhang, Xuan Tang, Xueshi Guo +3
Interference effects are usually observed by intensity measurement. Path indistinguishability by quantum complementarity principle requires projection of the interfering fields int…
Quantum dissipative dynamics of driven Duffing oscillator near attractors
Wei Feng, Lingzhen Guo
We investigate the quantum dissipative dynamics near the stable states (attractors) of a driven Duffing oscillator. A refined perturbation theory that can treat two perturbative pa…
Optical phase estimation via homodyne measurement in the presence of saturation effect of photodetectors
Jialin Li, Yazhi Niu, Lupei Qin +1
For optical phase estimation via homodyne measurement, we generalize the theory from detector's linear to nonlinear response regime, which accounts for the presence of saturation e…
