Kavli Affiliate: Andrei Faraon | First 5 Authors: Andrei Ruskuc, Chun-Ju Wu, Jake Rochman, Joonhee Choi, Andrei Faraon | Summary: Solid-state nuclear spins surrounding individual, optically addressable qubits provide a crucial resource for quantum networks, computation and simulation. While hosts with sparse nuclear spin baths are typically chosen to mitigate qubit decoherence, developing coherent quantum […]
Kavli Affiliate: J. Todd Hoeksema | First 5 Authors: Richard E. L. Higgins, David F. Fouhey, Spiro K. Antiochos, Graham Barnes, Mark C. M. Cheung | Summary: Both NASA’s Solar Dynamics Observatory (SDO) and the JAXA/NASA Hinode mission include spectropolarimetric instruments designed to measure the photospheric magnetic field. SDO’s Helioseismic and Magnetic Imager (HMI) emphasizes […]
Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Zeng-Zhao Li, Juan Atalaya, K. Birgitta Whaley, , | Summary: Topological quantum interference emerges from the interplay between quantum mechanics and topology. We present evidence for two types of such interference phenomenon that can result from the quantum dynamics of initial topological states. We realize both […]
Kavli Affiliate: David T. Limmer | First 5 Authors: Nathan Ng, David T. Limmer, Eran Rabani, , | Summary: When deriving exact generalized master equations for the evolution of a reduced set of degrees of freedom, one is free to choose what quantities are relevant by specifying projection operators. However, obtaining a reduced description does […]
Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Eliya Blumenthal, Chen Mor, Asaf A. Diringer, Leigh S. Martin, Philippe Lewalle | Summary: The Zeno effect occurs in quantum systems when a very strong measurement is applied, which can alter the dynamics in non-trivial ways. Despite being dissipative, the dynamics stay coherent within any degenerate […]
Kavli Affiliate: Ali Hajimiri | First 5 Authors: Aroutin Khachaturian, Reza Fatemi, Ali Hajimiri, , | Summary: Integrated photonic active beamforming can significantly reduce the size and cost of coherent imagers for LiDAR and medical imaging applications. In current architectures, the complexity of photonic and electronic circuitry linearly increases with the desired imaging resolution. We […]
Kavli Affiliate: Alex Zettl | First 5 Authors: Zuocheng Zhang, Emma C. Regan, Danqing Wang, Wenyu Zhao, Shaoxin Wang | Summary: Moir’e superlattices in van der Waals heterostructures have emerged as a powerful tool for engineering novel quantum phenomena. Here we report the observation of a correlated interlayer exciton insulator in a double-layer heterostructure composed […]
Kavli Affiliate: David T. Limmer | First 5 Authors: Avishek Das, Benjamin Kuznets-Speck, David T. Limmer, , | Summary: Active matter represents a broad class of systems that evolve far from equilibrium due to the local injection of energy. Like their passive analogues, transformations between distinct metastable states in active matter proceed through rare fluctuations, […]
Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Tiancong Zhu, Wei Ruan, Yan-Qi Wang, Hsin-Zon Tsai, Shuopei Wang | Summary: One-dimensional electron systems (1DESs) exhibit properties that are fundamentally different from higher-dimensional systems. For example, electron-electron interactions in 1DESs have been predicted to induce Tomonaga-Luttinger liquid behavior. Naturally-occurring grain boundaries in single-layer semiconducting transition […]
Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Yulong Dong, K. Birgitta Whaley, Lin Lin, , | Summary: Hamiltonian simulation is one of the most important problems in quantum computation, and quantum singular value transformation (QSVT) is an efficient way to simulate a general class of Hamiltonians. However, the QSVT circuit typically involves multiple […]
