In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

Quantum f-divergences are a quantum generalization of the classical notion of f-
divergences, and are a special case of Petz'quasi-entropies. Many well-known …

Certain algorithms for quantum computers are able to outperform their classical
counterparts. In 1994, Peter Shor came up with a quantum algorithm that calculates the …

Traditionally, quantum entanglement has been central to foundational discussions of
quantum mechanics. The measurement of correlations between entangled particles can …

A quantum processor can be used to exploit quantum mechanics to find the prime factors of
composite numbers. Compiled versions of Shor's algorithm and Gauss sum factorizations …

Quantum repeaters hold promise for scalable long-distance quantum communication. The
basic building block is a quantum light–matter interface that generates non-classical …

By pulsed s-shell resonant excitation of a single quantum dot-micropillar system, we
generate long streams of 1000 near-transform-limited single photons with high mutual …

The coupling of distinct systems underlies nearly all physical phenomena. A basic instance
is that of interacting harmonic oscillators, giving rise to, for example, the phonon …

Probing the polarization of water molecules at charged interfaces by second harmonic
generation spectroscopy has been heretofore limited to isotropic materials. Here we report …

Losses in superconducting planar resonators are presently assumed to predominantly arise
from surface-oxide dissipation, due to experimental losses varying with choice of materials …
