Tuning color centers at a twisted interface

Kavli Affiliate: Michael Crommie | First 5 Authors: Cong Su, Fang Zhang, Salman Kahn, Brian Shevitski, Jingwei Jiang | Summary: Color center is a promising platform for quantum technologies, but their application is hindered by the typically random defect distribution and complex mesoscopic environment. Employing cathodoluminescence, we demonstrate that an ultraviolet-emitting single photon emitter can […]

Imaging gate-tunable Tomonaga-Luttinger liquids in 1H-MoSe$_2$ mirror twin boundaries

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 […]

A quantum hamiltonian simulation benchmark

Kavli Affiliate: 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 ancilla […]

Forecasting racial dynamics at the neighborhood scale using Density-functional Fluctuation Theory

Kavli Affiliate: Itai Cohen | First 5 Authors: Yunus A. Kinkhabwala, Boris Barron, Matthew Hall, Tomas A. Arias, Itai Cohen | Summary: Racial residential segregation is a defining and enduring feature of U.S. society, shaping inter-group relations, racial disparities in income and health, and access to high-quality public goods and services. The design of policies […]

Fast universal quantum control above the fault-tolerance threshold in silicon

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Akito Noiri, Kenta Takeda, Takashi Nakajima, Takashi Kobayashi, Amir Sammak | Summary: Fault-tolerant quantum computers which can solve hard problems rely on quantum error correction. One of the most promising error correction codes is the surface code, which requires universal gate fidelities exceeding the error correction threshold […]

Measuring photoexcited electron and hole dynamics in ZnTe and modeling excited state core-valence effects in transient XUV reflection spectroscopy

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Hanzhe Liu, Jonathan M. Michelsen, Isabel M. Klein, Scott K. Cushing, | Summary: Transient XUV spectroscopy is growing in popularity for the measurement of solar fuel and photovoltaic materials as it can separately measure electron and hole energies for multiple elements at once. However, interpretation of […]

Topological Optical Parametric Oscillation

Kavli Affiliate: Alireza Marandi | First 5 Authors: Arkadev Roy, Midya Parto, Rajveer Nehra, Christian Leefmans, Alireza Marandi | Summary: Topological insulators possess protected boundary states which are robust against disorders and have immense implications in both fermionic and bosonic systems. Harnessing these topological effects in non-equilibrium scenarios is highly desirable and has led to […]
