Deterministic realization of collective measurements via photonic quantum walks
Zhibo Hou, Jun-Feng Tang, Jiangwei Shang +7
Collective measurements on identically prepared quantum systems can extract more information than local measurements, thereby enhancing information-processing efficiency. Although…
Universally Fisher-Symmetric Informationally Complete Measurements
Huangjun Zhu, Masahito Hayashi
A quantum measurement is Fisher symmetric if it provides uniform and maximal information on all parameters that characterize the quantum state of interest. Using (complex projectiv…
Generalized Entanglement Entropies of Quantum Designs
Zi-Wen Liu, Seth Lloyd, Elton Yechao Zhu +1
The entanglement properties of random quantum states or dynamics are important to the study of a broad spectrum of disciplines of physics, ranging from quantum information to high…
Secure uniform random number extraction via incoherent strategies
Masahito Hayashi, Huangjun Zhu
To guarantee the security of uniform random numbers generated by a quantum random number generator, we study secure extraction of uniform random numbers when the environment of a g…
Coherence and entanglement measures based on Rényi relative entropies
Huangjun Zhu, Masahito Hayashi, Lin Chen
We study systematically resource measures of coherence and entanglement based on Rényi relative entropies, which include the logarithmic robustness of coherence, geometric coherenc…
Axiomatic and operational connections between the -norm of coherence and negativity
Huangjun Zhu, Masahito Hayashi, Lin Chen
Quantum coherence plays a central role in various research areas. The -norm of coherence is one of the most important coherence measures that are easily computable, but it is…
Operational one-to-one mapping between coherence and entanglement measures
Huangjun Zhu, Zhihao Ma, Zhu Cao +2
We establish a general operational one-to-one mapping between coherence measures and entanglement measures: Any entanglement measure of bipartite pure states is the minimum of a su…
Entanglement, quantum randomness, and complexity beyond scrambling
Zi-Wen Liu, Seth Lloyd, Elton Yechao Zhu +1
Scrambling is a process by which the state of a quantum system is effectively randomized due to the global entanglement that "hides" initially localized quantum information. In thi…
Introducing the Qplex: A Novel Arena for Quantum Theory
Marcus Appleby, Christopher A. Fuchs, Blake C. Stacey +1
We reconstruct quantum theory starting from the premise that, as Asher Peres remarked, "Unperformed experiments have no results." The tools of modern quantum information theory, an…
