Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Akel Hashim, Rich Rines, Victory Omole, Ravi K. Naik, John Mark Kreikebaum | Summary: The fermionic SWAP network is a qubit routing sequence that can be used to efficiently execute the Quantum Approximate Optimization Algorithm (QAOA). Even with a minimally-connected topology on an n-qubit processor, this routing […]
Kavli Affiliate: Alessandra Lanzara | First 5 Authors: Ryo Mori, Kefeng Wang, Takahiro Morimoto, Jonathan D. Denlinger, Johnpierre Paglione | Summary: A topological flatband, also known as drumhead states, is an ideal platform to drive new exotic topological quantum phases. Using angle-resolved photoemission spectroscopy experiments, we reveal the emergence of a highly localized possible drumhead […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Michael J. Motala, Xiang Zhang, Pawan Kumar, Eliezer F. Oliveira, Anna Benton | Summary: Heterostructure materials form the basis of much of modern electronics, from transistors to lasers and light-emitting diodes. Recent years have seen a renewed focus on creating heterostructures through the vertical integration of two-dimensional […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Changhao Wang, Zhian Kuang, Xiang Zhang, Masayoshi Tomizuka, | Summary: Smooth behaviors are preferable for many contact-rich manipulation tasks. Impedance control arises as an effective way to regulate robot movements by mimicking a mass-spring-damping system. Consequently, the robot behavior can be determined by the impedance gains. However, […]
Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Robert L. Cook, Liwen Ko, K. Birgitta Whaley, , | Summary: In this work we study the first step in photosynthesis for the limiting extreme case of a single photon interacting with photosystem II (PSII). We model our system using quantum trajectory theory, which allows us […]
Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Shufeng Kong, Francesco Ricci, Dan Guevarra, Jeffrey B. Neaton, Carla P. Gomes | Summary: Machine learning for materials discovery has largely focused on predicting an individual scalar rather than multiple related properties, where spectral properties are an important example. Fundamental spectral properties include the phonon density […]
Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Ian Convy, K. Birgitta Whaley, , , | Summary: We consider the problem of continuous quantum error correction from a Bayesian perspective, proposing a pair of digital filters using logarithmic probabilities that are able to achieve near-optimal performance on a three-qubit bit-flip code while still being […]
Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Ian Convy, Haoran Liao, Song Zhang, Sahil Patel, William P. Livingston | Summary: We propose a machine learning algorithm for continuous quantum error correction that is based on the use of a recurrent neural network to identity bit-flip errors from continuous noisy syndrome measurements. The algorithm […]
Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Zeng-Zhao Li, Liwen Ko, Zhibo Yang, Mohan Sarovar, K. Birgitta Whaley | Summary: We study the interplay between two environmental influences on excited state energy transfer in photosynthetic light harvesting complexes, namely, vibrationally assisted energy transfer(VAET) and environment-assisted quantum transport (ENAQT), considering a dimeric chromophore donor-acceptor […]
Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Tao Kong, Rufeng Zhang, Huaping Liu, Hang Li | Summary: We present TWIST, a simple and theoretically explainable self-supervised representation learning method by classifying large-scale unlabeled datasets in an end-to-end way. We employ a siamese network terminated by a softmax operation to produce twin class […]
