Exploring the trade-off between fidelity- and time-optimal control of quantum unitary transformations
Katharine W. Moore Tibbetts, Constantin Brif, Matthew D. Grace +5
Generating a unitary transformation in the shortest possible time is of practical importance to quantum information processing because it helps to reduce decoherence effects and im…
Fast generation of multiparticle entangled state for flux qubits in a circle array of transmission line resonators with tunable coupling
Z. H. Peng, Yu-xi Liu, Y. Nakamura +1
We study a one-step approach to the fast generation of Greenberger-Horne-Zeilinger (GHZ) states in a circuit QED system with superconducting flux qubits. The GHZ state can be gener…
Multipartite electronic entanglement purification with charge detection
Yu-Bo Sheng, Fu-Guo Deng, Gui-Lu Long
We present a multipartite entanglement purification scheme in a Greenberger-Horne-Zeilinger state for electrons based on their spins and their charges. This scheme works for purifi…
A gravitational wave observatory operating beyond the quantum shot-noise limit: Squeezed light in application
The LIGO Scientific Collaboration
Around the globe several observatories are seeking the first direct detection of gravitational waves (GWs). These waves are predicted by Einstein's General Theory of Relativity [Ei…
Perfect discrimination of no-signalling channels via quantum superposition of causal structures
G. Chiribella
A no-signalling channel transforming quantum systems in Alice's and Bob's laboratories is compatible with two different causal structures: (A < B) Alice's output causally precedes…
Entanglement detection in the vicinity of arbitrary Dicke states
L. -M. Duan
Dicke states represent a class of multipartite entangled states that can be generated experimentally with many applications in quantum information. We propose a method to experimen…
Aharon-Vaidman quantum game with a Young-type photonic qutrit
Piotr Kolenderski, Urbasi Sinha, Li Youning +5
The Aharon-Vaidman (AV) game exemplifies the advantage of using simple quantum systems to outperform classical strategies. We present an experimental test of this advantage by usin…
Four Locally Indistinguishable Ququad-Ququad Orthogonal Maximally Entangled States
Nengkun Yu, Runyao Duan, Mingsheng Ying
We explicitly exhibit a set of four ququad-ququad orthogonal maximally entangled states that cannot be perfectly distinguished by means of local operations and classical communicat…
Rank-based SLOCC classification for odd n qubits
Xiangrong Li, Dafa Li
We study the entanglement classification under stochastic local operations and classical communication (SLOCC) for odd n-qubit pure states. For this purpose, we introduce the rank…
Classification of general n-qubit states under stochastic local operations and classical communication in terms of the rank of coefficient matrix
Xiangrong Li, Dafa Li
We solve the entanglement classification under stochastic local operations and classical communication (SLOCC) for general n-qubit states. For two arbitrary pure n-qubit states con…
SLOCC determinant invariants of order 2^{n/2} for even n qubits
Xiangrong Li, Dafa Li
In this paper, we study SLOCC determinant invariants of order 2^{n/2} for any even n qubits which satisfy the SLOCC determinant equations. The determinant invariants can be constru…
Observation of Fast Evolution in Parity-Time-Symmetric System
Chao Zheng, Liang Hao, Gui Lu Long
To find and realize the optimal evolution between two states is significant both in theory and application. In quantum mechanics, the minimal evolution is bounded by the gap betwee…
Unambiguous discrimination between two unknown qudit states
Tao Zhou
We consider the unambiguous discrimination between two unknown qudit states in -dimensional () Hilbert space. By equivalence of unknown pure states to known mixed s…
Comment on "Are There Traps in Quantum Control Landscapes?"
Herschel Rabitz, Tak-San Ho, Ruixing Long +2
Many quantum control problems are formulated as a search for an optimal field that maximizes a physical objective. This search is performed over a landscape defined as the objectiv…
Photon Induced Entanglement in Atom-Cavity Systems
Li-Li Lan, Xiang-Bin Wang, Shao-Ming Fei
We study the evolution of quantum entanglement in double cavity systems. The entanglement of cavity atoms induced by entangled pair of photons is investigated. Both entanglement su…
Complete hyperentangled-Bell-state analysis for quantum communication
Yu-Bo Sheng, Fu-Guo Deng, Gui Lu Long
It is impossible to unambiguously distinguish the four Bell states in polarization, resorting to linear optical elements only. Recently, the hyperentangled Bell state, the simultan…
Quantum Coherent Nonlinear Feedbacks with Applications to Quantum Optics on Chip
Jing Zhang, Re-Bing Wu, Yu-xi Liu +2
In the control of classical mechanical systems, the feedback has been successfully applied to the production of the desired nonlinear dynamics. However, how much this can be done i…
Fidelity Between Unitary Operators and the Generation of Gates Robust Against Off-Resonance Perturbations
Renan Cabrera, Ofer M. Shir, Rebing Wu +1
We perform a functional expansion of the fidelity between two unitary matrices in order to find the necessary conditions for the robust implementation of a target gate. Comparison…
Chaos can act as a decoherence suppressor
Jing Zhang, Yu-xi Liu, Wei-Min Zhang +3
We propose a strategy to suppress decoherence of a solid-state qubit coupled to non-Markovian noises by attaching the qubit to a chaotic setup with the broad power distribution in…

Monika Bartkowiak, Adam Miranowicz, Xiaoguang Wang +3
Analyses of phenomena exhibiting finite-time decay of quantum entanglement have recently attracted considerable attention. Such decay is often referred to as sudden vanishing (or s…
