Quantum signatures of chaos in a kicked top
TL;DR: This work presents the experimental realization of a common paradigm for quantum chaos—the quantum kicked top— and the observation directly in quantum phase space of dynamics that have a chaotic classical counterpart, and presents experimental evidence for dynamical entanglement as a signature of chaos.

TL;DR: It is found that this method reduces the dephasing effect of charge noise by more than a factor of 5 in comparison to operation near a charge-state anticrossing, increasing the number of observable exchange oscillations in the authors' qubit by a similar factor.
Isotopically enhanced triple-quantum-dot qubit.

TL;DR: This work demonstrates universal coherent control of a triple-quantum-dot qubit implemented in an isotopically enhanced Si/SiGe heterostructure and demonstrates sufficient control with sufficiently low noise to enable the long pulse sequences required for exchange-only two-qubit logic and randomized benchmarking.

TL;DR: In this article , a single-layer etch-defined gate electrode architecture was proposed to achieve the required functional yield needed for full control and the coherence necessary for thousands of calibrated exchange pulses to be applied.

Quantum state tomography by continuous measurement and compressed sensing
Aaron Smith,Carlos Riofrio,Brian E. Anderson,H. Sosa-Martinez,Ivan H. Deutsch,Poul S. Jessen +5 more
TL;DR: In this article, the performance of compressed sensing (CS) and least squares (LS) estimators in a fast protocol based on continuous measurement on an ensemble of cesium atomic spins was investigated.
