Single-Shot Readout of a Nuclear Spin Weakly Coupled to a Nitrogen-Vacancy Center

Gang-Qin Liu, Jian Xing, Wen-Long Ma +5

Single-shot readout of qubits is required for scalable quantum computing. Nuclear spins are superb quantum memories due to their long coherence times but are difficult to be read o…

Invariant Perfect Tensors

Youning Li, Muxin Han, Markus Grassl +1

Invariant tensors are states in the SU(2) tensor product representation that are invariant under the SU(2) action. They play an important role in the study of loop quantum gravity.…

Understanding quantum work in a quantum many-body system

Qian Wang, H. T. Quan

Based on previous studies in a single particle system in both the integrable [Jarzynski, Quan, and Rahav, Phys.~Rev.~X {\bf 5}, 031038 (2015)] and the chaotic systems [Zhu, Gong, W…

Relative quantum coherence, incompatibility, and quantum correlations of states

Ming-Liang Hu, Heng Fan

Quantum coherence, incompatibility, and quantum correlations are fundamental features of quantum physics. A unified view of those features is crucial for revealing quantitatively t…

Correlation based entanglement criteria for bipartite systems

Yumang Jing, Qiongyi He, Tim Byrnes

We introduce a class of inequalities based on low order correlations of operators to detect entanglement in bipartite systems. The operators may either be Hermitian or non-Hermitia…

Spin-Orbit Coupling Induced Spin Squeezing in Three-Component Bose Gases

X. Y. Huang, F. X. Sun, W. Zhang +2

We observe spin squeezing in three-component Bose gases where all three hyperfine states are coupled by synthetic spin-orbit coupling. This phenomenon is a direct consequence of sp…

Variance-based uncertainty relations for incompatible observables

Bin Chen, Ning-Ping Cao, Shao-Ming Fei +1

We formulate uncertainty relations for arbitrary finite number of incompatible observables. Based on the sum of variances of the observables, both Heisenberg-type and Schrödinger-t…

Minimum-Time Selective Control of Homonuclear Spins

Tian-Ming Zhang, Re-Bing Wu, Fei-Hao Zhang +2

In NMR (Nuclear Magnetic Resonance) quantum computation, the selective control of multiple homonuclear spins is usually slow because their resonance frequencies are very close to e…

Sum uncertainty relations based on Wigner-Yanase skew information

Bin Chen, Shao-Ming Fei, Gui-Lu Long

We study sum uncertainty relations for arbitrary finite quantum mechanical observables. Some uncertainty inequalities are presented by using skew information introduced by Wign…

Measurement of linear response functions in Nuclear Magnetic Resonance

Tao Xin, Julen S. Pedernales, Lucas Lamata +2

We measure multi-time correlation functions of a set of Pauli operators on a two-level system, which can be used to retrieve its associated linear response functions. The two-level…

Multipartite Gaussian steering: monogamy constraints and quantum cryptography applications

Yu Xiang, Ioannis Kogias, Gerardo Adesso +1

We derive laws for the distribution of quantum steering among different parties in multipartite Gaussian states under Gaussian measurements. We prove that a monogamy relation akin…

Unconditional security of entanglement-based continuous-variable quantum secret sharing

Ioannis Kogias, Yu Xiang, Qiongyi He +1

The need for secrecy and security is essential in communication. Secret sharing is a conventional protocol to distribute a secret message to a group of parties, who cannot access i…

Steering Bell-diagonal states

Quan Quan, Huangjun Zhu, Si-Yuan Liu +3

We investigate the steerability of two-qubit Bell-diagonal states under projective measurements by the steering party. In the simplest nontrivial scenario of two projective measure…

Entanglement Spectrum of Su-Schrieffer-Heeger-Hubbard Model

Bing-Tian Ye, Liang-Zhu Mu, Heng Fan

We investigate the entanglement spectrum of the ground state of Su-Schrieffer-Heeger-Hubbard model. The topological phases of the model can be identified by degeneracy of the large…

Persistent atomic spin squeezing at the Heisenberg limit

Ling-Na Wu, Meng Khoon Tey, L. You

Two well-known mechanisms, one-axis twisting (OAT) and two-axis countertwisting (TACT), generate spinsqueezed states dynamically. The latter provides better spin squeezing (SS) but…

Einstein-Podolsky-Rosen correlations and Bell correlations in the simplest scenario

Quan Quan, Huangjun Zhu, Heng Fan +1

Einstein-Podolsky-Rosen (EPR) steering is an intermediate type of quantum nonlocality which sits between entanglement and Bell nonlocality. A set of correlations is Bell nonlocal i…
