Model-Checking Linear-Time Properties of Quantum Systems
Mingsheng Ying, Yangjia Li, Nengkun Yu +1
We define a formal framework for reasoning about linear-time properties of quantum systems in which quantum automata are employed in the modeling of systems and certain closed subs…
Optimal Quantum State Estimation with Use of the No-Signaling Principle
Yeong-Deok Han, Joonwoo Bae, Xiang-Bin Wang +1
A simple derivation of the optimal state estimation of a quantum bit was obtained by using the no-signaling principle. In particular, the no-signaling principle determines a unique…
Protecting Two-Qubit Quantum States by -Phase Pulses
Jia-Zhong Hu, Xiang-Bin Wang, LC Kwek
We study the state decay of two qubits interacted with a common harmonic oscillator reservoir. There are both decoherence error and the error caused by the amplitude change of the…
Quantum-limited metrology in the presence of collisional dephasing
Y. C. Liu, G. R. Jin, L. You
Including collisional decoherence explicitly, phase sensitivity for estimating effective scattering strength of a two-component Bose-Einstein condensate is derived analytically…
Any subspace is locally distinguishable
Nengkun Yu, Runyao Duan, Mingsheng Ying
A subspace of a multipartite Hilbert space is called \textit{locally indistinguishable} if any orthogonal basis of this subspace cannot be perfectly distinguished by local operatio…
Faithful entanglement sharing for quantum communication against collective noise
Hui-Chong Niu, Bao-Cang Ren, Tie-Jun Wang +2
We present an economical setup for faithful entanglement sharing against collective noise. It is composed of polarizing beam splitters, half wave plates, polarization independent w…
Teleportation transfers only speakable quantum information
G. Chiribella, V. Giovannetti, L. Maccone +1
We show that a quantum clock cannot be teleported without prior synchronization between sender and receiver: every protocol using a finite amount of entanglement and an arbitrary n…
Realization of Quantum State Privacy Amplification in a Nuclear Magnetic Resonance Quantum System
Liang Hao, Chuan Wang, Gui Lu Long
Quantum state privacy amplification (QSPA) is the quantum analogue of classical privacy amplification. If the state information of a series of single particle states has some leaka…
Noise Performance Comparison of 1.5 um Correlated Photon Pair Generation in Different Fibers
Qiang Zhou, Wei Zhang, Jie-rong Cheng +2
In this paper, the noise performances of 1.5 um correlated photon pair generations based on spontaneous four wave-mixing in three types of fibers, i.e., dispersion shifted fiber, h…
No-go Theorem for One-way Quantum Computing on Naturally Occurring Two-level Systems
Jianxin Chen, Xie Chen, Runyao Duan +2
One-way quantum computing achieves the full power of quantum computation by performing single particle measurements on some many-body entangled state, known as the resource state.…
Testing nonclassicality in multimode fields: a unified derivation of classical inequalities
Adam Miranowicz, Monika Bartkowiak, Xiaoguang Wang +2
We consider a way to generate operational inequalities to test nonclassicality (or quantumness) of multimode (or multiparty) bosonic fields that unifies the derivation of many know…
Relationship between the n-tangle and the residual entanglement of even n qubits
X. Li, D. Li
We show that -tangle, the generalization of the 3-tangle to even qubits, is the square of the SLOCC polynomial invariant of degree 2. We find that the -tangle is not the…
Tensor Rank and Stochastic Entanglement Catalysis for Multipartite Pure States
Lin Chen, Eric Chitambar, Runyao Duan +2
The tensor rank (also known as generalized Schmidt rank) of multipartite pure states plays an important role in the study of entanglement classifications and transformations. We em…
Coexistence of multi-photon processes and longitudinal couplings in superconducting flux qubits
Yu-xi Liu, Cheng-Xi Yang, Hui-Chen Sun +1
In contrast to natural atoms, the potential energies for superconducting flux qubit (SFQ) circuits can be artificially controlled. When the inversion symmetry of the potential ener…
Quantum state reduction for universal measurement based computation
Xie Chen, Runyao Duan, Zhengfeng Ji +1
Measurement based quantum computation (MBQC), which requires only single particle measurements on a universal resource state to achieve the full power of quantum computing, has bee…
Thermalization and temperature distribution in a driven ion chain
G. -D. Lin, L. -M. Duan
We study thermalization and non-equilibrium dynamics in a dissipative quantum many-body system -- a chain of ions with two points of the chain driven by thermal bath under differen…
Multi-Error-Correcting Amplitude Damping Codes
Runyao Duan, Markus Grassl, Zhengfeng Ji +1
We construct new families of multi-error-correcting quantum codes for the amplitude damping channel. Our key observation is that, with proper encoding, two uses of the amplitude da…
Entanglement distribution maximization over one-side Gaussian noisy channel
Xiang-Bin Wang, Zong-Wen Yu, Jia-Zhong Hu
The optimization of entanglement evolution for two-mode Gaussian pure states under one-side Gaussian map is studied. Even there isn't complete information about the one-side Gaussi…
