A shuttling-based two-qubit logic gate for linking distant silicon quantum processors

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Akito Noiri, Kenta Takeda, Takashi Nakajima, Takashi Kobayashi, Amir Sammak | Summary: Control of entanglement between qubits at distant quantum processors using a two-qubit gate is an essential function of a scalable, modular implementation of quantum computation. Among the many qubit platforms, spin qubits in silicon quantum […]

Deep sub-wavelength localization of light and sound in dielectric resonators

Kavli Affiliate: Mohammad Mirhosseini | First 5 Authors: Alkim Bozkurt, Chaitali Joshi, Mohammad Mirhosseini, , | Summary: Optomechanical crystals provide coupling between phonons and photons by confining them to commensurate wavelength-scale dimensions. We present a new concept for designing optomechanical crystals capable of achieving unprecedented coupling rates by confining optical and mechanical waves to deep […]

Active entanglement enables stochastic, topological grasping

Kavli Affiliate: Robert Wood | First 5 Authors: Kaitlyn Becker, Clark Teeple, Nicholas Charles, Yeonsu Jung, Daniel Baum | Summary: Grasping, in both biological and engineered mechanisms, can be highly sensitive to the gripper and object morphology, as well as perception, and motion planning. Here we circumvent the need for feedback or precise planning by […]

An Optimally-Tuned Starting Point for Single-Shot $GW$ Calculations of Solids

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Stephen E. Gant, Jonah B. Haber, Marina R. Filip, Francisca Sagredo, Dahvyd Wing | Summary: The dependence of ab initio many-body perturbation theory within the $GW$ approximation on the eigensystem used in calculating quasiparticle corrections limits this method’s predictive power. Here, we investigate the accuracy of […]

Dielectric catastrophe at the Mott and Wigner transitions in a moiré superlattice

Kavli Affiliate: Jie Shan | First 5 Authors: Yanhao Tang, Jie Gu, Song Liu, Kenji Watanabe, Takashi Taniguchi | Summary: The metal-insulator transition (MIT) driven by electronic correlations is a fundamental and challenging problem in condensed-matter physics. Particularly, whether such a transition can be continuous remains open. The emergence of semiconducting moir’e materials with continuously […]
