Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Alexis Morvan, Larry Chen, Jeffrey M. Larson, David I. Santiago, Irfan Siddiqi | Summary: Fixed-frequency superconducting quantum processors are one of the most mature quantum computing architectures with high-coherence qubits and low-complexity controls. However, high-fidelity multi-qubit gates pose tight requirements on individual qubit frequencies in these processors […]

Kavli Affiliate: Feng Wang | First 5 Authors: Tingting Xu, Chao Liu, Feng Wang, Weirong Huang, Hui Deng | Summary: The identification and analysis of different variable sources is a hot issue in astrophysical research. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) spectroscopic survey has accumulated massive spectral data but contains no information […]

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Evan Sheridan, Thomas F. Harrelson, Eric Sivonxay, Kristin A. Persson, M. Virginia P. Altoé | Summary: The performance of superconducting qubits is orders of magnitude below what is expected from theoretical estimates based on the loss tangents of the constituent bulk materials. This has been attributed […]

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Thomas F. Harrelson, Evan Sheridan, Ellis Kennedy, John Vinson, Alpha T. N’Diaye | Summary: Qubits made from superconducting materials are a mature platform for quantum information science application such as quantum computing. However, materials-based losses are now a limiting factor in reaching the coherence times needed for […]

Kavli Affiliate: Joel Moore | First 5 Authors: Shannon C. Haley, Eran Maniv, Tessa Cookmeyer, Susana Torres-Londono, Meera Aravinth | Summary: Antiferromagnetic spintronics is an emerging area of quantum technologies that leverage the coupling between spin and orbital degrees of freedom in exotic materials. Spin-orbit interactions allow spin or angular momentum to be injected via […]

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Mykola Telychko, Keian Noori, Hillol Biswas, Dikshant Dulal, Pin Lyu | Summary: We report an atomically-precise integration of individual nitrogen (N) dopant as an in-plane artificial nucleus in a graphene device by atomic implantation to probe its gate-tunable quantum states and correlation effects. The N dopant […]

Kavli Affiliate: David T. Limmer | First 5 Authors: Aditya N. Singh, David T. Limmer, , , | Summary: We use molecular dynamics simulations to study the thermodynamics and kinetics of alanine dipeptide isomerization at the air-water interface. Thermodynamically, we find an affinity of the dipeptide to the interface. This affinity arises from stablizing intramolecular […]

Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Liwen Ko, Robert L. Cook, K. Birgitta Whaley, , | Summary: We develop a method to simulate the excitonic dynamics of realistic photosynthetic light harvesting systems including non-Markovian coupling to phonon degrees of freedom, under excitation by N-photon Fock state pulses. This method combines the input-output […]

Kavli Affiliate: Feng Wang | First 5 Authors: Jiangchao Yao, Shengyu Zhang, Yang Yao, Feng Wang, Jianxin Ma | Summary: Influenced by the great success of deep learning via cloud computing and the rapid development of edge chips, research in artificial intelligence (AI) has shifted to both of the computing paradigms, i.e., cloud computing and […]
