Probing quantum phase slips in superconducting nanowires modified using high bias voltage pulses
Quantum phase slips (QPS) or the macroscopic quantum tunneling (MQT) of a nanowire’s order parameter through an activation energy barrier have remained the subject of intense debate for many years. They are expected to occur at low enough temperature where thermally activated phase slips (TAPS) …

Size Effects on Transport in Graphene
… of resistivity versus width was well fitted by a quantum model which assumes ballistic transport in graphene but diffusive scattering at the edges. From this model, the electron mean free path for conduction was extracted to be between 50 and 200 nm, agreeing with reported values. Another …

Mother Tree Optimization for Solving Continuous and Discrete Optimization Problems
… Furthermore, we have applied MTO to create a quantum model to solve a hard quantum problem and to overcome the stagnation issue that the other methods su er from. We have also de ned a discrete version of MTO and a discrete variant of the Particle Swarm Optimization (PSO) algorithm, to tackle …

Statistical Methods For Resolving Intratumor Heterogeneity With Single-Cell Dna Sequencing
… (chapter 4). Previously proposed methods for quantum estimation were found to correctly infer ploidy from most cells, enabling inference of precise copy number in copy number aberrations. Additionally, a weighting procedure based on a probabilistic model of sequencing read counts (described in …
