Pseudogap in a Fermi-Hubbard quantum simulator
Lev Haldar Kendrick, Anant Kale, Youqi Gang +4
Understanding doped Mott insulators is a fundamental goal in condensed matter physics, with relevance to cuprate superconductors and other quantum materials. The doped Hubbard mode…
Architectural mechanisms of a universal fault-tolerant quantum computer
Dolev Bluvstein, Alexandra A. Geim, Sophie H. Li +20
Quantum error correction (QEC) is believed to be essential for the realization of large-scale quantum computers. However, due to the complexity of operating on the encoded `logical…
Continuous operation of a coherent 3,000-qubit system
Neng-Chun Chiu, Elias C. Trapp, Jinen Guo +15
Neutral atoms are a promising platform for quantum science, enabling advances in areas ranging from quantum simulations and computation to metrology, atomic clocks and quantum netw…
Optimized Gutzwiller Projected States for Doped Antiferromagnets in Fermi-Hubbard Simulators
Christian Reinmoser, Muqing Xu, Lev Haldar Kendrick +6
In quantum many-body physics, one aims to understand emergent phenomena and effects of strong interactions, ideally by developing a simple theoretical picture. Recently, progress i…
Canted magnetism and fractionalization in metallic states of the Lieb lattice Hubbard model near quarter filling
Alexander Nikolaenko, Pietro M. Bonetti, Anant Kale +3
A recent experiment has examined ultracold, fermionic, spin-1/2 Li atoms in the Lieb lattice at different Hubbard repulsion and filling fractions (Lebrat et al. arXiv:2…
A neutral-atom Hubbard quantum simulator in the cryogenic regime
Muqing Xu, Lev Haldar Kendrick, Anant Kale +6
Ultracold fermionic atoms in optical lattices offer pristine realizations of Hubbard models, which are fundamental to modern condensed matter physics. Despite significant advanceme…
Probing the Kitaev honeycomb model on a neutral-atom quantum computer
Simon J. Evered, Marcin Kalinowski, Alexandra A. Geim +15
Quantum simulations of many-body systems are among the most promising applications of quantum computers. In particular, models based on strongly-correlated fermions are central to…
