Adaptive Algorithm for Quantum Amplitude Estimation

Kavli Affiliate: Feng Wang | First 5 Authors: Yunpeng Zhao, Haiyan Wang, Kuai Xu, Yue Wang, Ji Zhu | Summary: Quantum amplitude estimation is a key sub-routine of a number of quantum algorithms with various applications. We propose an adaptive algorithm for interval estimation of amplitudes. The quantum part of the algorithm is based only […]

Cold Gas Reservoirs of Low- and High-mass Central Galaxies Differ in Response to Active Galactic Nucleus Feedback

Kavli Affiliate: Jing Wang | First 5 Authors: Hong Guo, Michael G. Jones, Jing Wang, , | Summary: The growth of supermassive black holes, especially the associated state of active galactic nuclei (AGNs), is generally believed to be the key step in regulating star formation in massive galaxies. As the fuel of star formation, the […]

Binaries Wandering Around Supermassive Black Holes Due To Gravito-electromagnetism

Kavli Affiliate: Xian Chen | First 5 Authors: Xian Chen, Zhongfu Zhang, , , | Summary: Extreme-mass-ratio inspirals (EMRIs) are important sources for space-borne gravitational-wave (GW) detectors. Such a source normally consists of a stellar-mass black hole (BH) and a Kerr supermassive BH (SMBH), but recent astrophysical models predict that the small body could also […]

Conformally-rescaled Schwarzschild metrics do not predict flat galaxy rotation curves

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, , , | Summary: For conformally invariant gravity theories defined on Riemannian spacetime and having the Schwarzschild–de-Sitter (SdS) metric as a solution in the Einstein gauge, we consider whether one may conformally rescale this solution to obtain flat rotation curves, such as those […]

Realization of a minimal Kitaev chain in coupled quantum dots

Kavli Affiliate: Michael Wimmer | First 5 Authors: Tom Dvir, Guanzhong Wang, Nick van Loo, Chun-Xiao Liu, Grzegorz P. Mazur | Summary: Majorana bound states constitute one of the simplest examples of emergent non-Abelian excitations in condensed matter physics. A toy model proposed by Kitaev shows that such states can arise at the ends of […]
