Dynamical localization in 2D topological quantum random walks

Kavli Affiliate: Eliska Greplova | First 5 Authors: D. O. Oriekhov, Guliuxin Jin, Eliska Greplova, , | Summary: We study the dynamical localization of discrete time evolution of topological split-step quantum random walk (QRW) on a single-site defect starting from a uniform distribution. Using analytical and numerical calculations, we determine the high localization probability regions […]

Probing universal critical scaling with scan-DMRG

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Natalia Chepiga, , , , | Summary: We explore the universal signatures of quantum phase transitions that can be extracted with the density matrix renormalization group (DMRG) algorithm applied to quantum chains with a gradient. We present high-quality data collapses for the order parameter and for the […]

Functional photoacoustic noninvasive Doppler angiography in humans

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Yang Zhang, Joshua Olick-Gibson, Karteekeya Sastry, Lihong V. Wang, | Summary: Optical imaging of blood flow yields critical functional insights into the circulatory system, but its clinical implementation has typically been limited to shallow depths (~1 millimeter) due to light scattering in biological tissue. Here, we […]

Solving k-SAT problems with generalized quantum measurement

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Yipei Zhang, Philippe Lewalle, K. Birgitta Whaley, , | Summary: We generalize the projection-based quantum measurement-driven $k$-SAT algorithm of Benjamin, Zhao, and Fitzsimons (BZF, arxiv:1711.02687) to arbitrary strength quantum measurements, including the limit of continuous monitoring. In doing so, we clarify that this algorithm is a particular […]
