Quantum-Enhanced Sensing Enabled by Scrambling-Induced Genuine Multipartite Entanglement

Guantian Hu, Wenxuan Zhang, Zhihua Chen, Liuzhu Zhong et autres

Quantum sensing leverages quantum resources to surpass the standard quantum limit, yet many existing protocols rely on the preparation of complex entangled states and Hamiltonian engineering, posing challenges for universality and scalability. Here, we report an experimental implementation of a universal butterfly …

Collective Dynamics in Circuit Quantum Acoustodynamics with a Macroscopic Resonator

Libo Zhang, Chilong Liu, Guixu Xie, Haolan Yuan et autres

Collective dynamics in engineered quantum systems offer a unique and versatile platform for exploring how many-body correlations bridge microscopic entanglement and macroscopic behavior. In this work, we report collective Dicke dynamics of acoustic modes in a macroscopic high-overtone bulk acoustic resonator (HBAR). …

Roadmap on quantum thermodynamics

Steve Campbell, Irene D’Amico, Mario A. Ciampini, Janet Anders et autres

Abstract The last two decades have seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicability, ranging from providing foundational advances in the understanding of how thermodynamic principles …

Noise-induced quantum synchronization with entangled oscillations

Ziyu Tao, Finn Schmolke, Chang-Kang Hu, Wenhui Huang et autres

Random fluctuations can lead to cooperative effects in complex systems. We here report the observation of noise-induced quantum synchronization in a chain of superconducting transmon qubits with nearest-neighbor interactions. The application of Gaussian white noise to a single site leads to synchronous …

Digital simulation of zero-temperature spontaneous symmetry breaking in a superconducting lattice processor

Chang-Kang Hu, Kasper Poulsen, Yuxuan Zhou, Ji Chu et autres

Quantum simulators are ideal platforms to investigate quantum phenomena that are inaccessible through conventional means, such as the limited resources of classical computers to address large quantum systems or due to constraints imposed by fundamental laws of nature. Here, through a digitized …
