Improved quantum algorithm for A-optimal projection
Shijie Pan, Lin-Chun Wan, Hailing Liu +4 more·Jun 10, 2020
Dimensionality reduction (DR) algorithms, which reduce the dimensionality of a given data set while preserving the information of original data set as well as possible, play an important role in machine learning and data mining. Duan et al. proposed ...
Quantifying entanglement preservability of experimental processes
Shih‐Hsuan Chen, Meng-Lok Ng, Che-Ming Li·Jun 9, 2020
Preserving entanglement is a crucial dynamical process for entanglement-based quantum computation and quantum-information processes, such as one-way quantum computing and quantum key distribution. However, how to quantify the ability of an experiment...
Quantum Metamaterials: Applications in quantum information science
S. Uriri, Y. Ismail, Francesco Petruccione·Jun 6, 2020
Metamaterials are artificially engineered periodic structures with exceptional optical properties that are not found in conventional materials. However, this definition of metamaterials can be extended if we introduce a quantum degree of freedom by a...

Holographic Pseudo Entropy
Y. Nakata, T. Takayanagi, Yusuke Taki +2 more·May 28, 2020
We introduce a new quantity, called pseudo-entropy, as a generalization of entanglement entropy via postselection. We expect this quantity to provide a new class of order parameters in quantum many-body systems. In the anti--de Sitter space (AdS)/con...
