Gaussian time-translation covariant operations: structure, implementation, and thermodynamics
Xueyuan Hu, Lea Lautenbacher, Giovanni Spaventa +3
Time-translation symmetry strongly constrains physical dynamics, yet systematic characterization for continuous-variable systems lags behind its discrete-variable counterpart. We c…
Open Quantum Systems Driven by Chirped Pulses: Quantized versus Semiclassical Fields and the Validity of the Rotating-Wave Approximation
Justin Zhengjie Tan, Frank GroÃmann, Yiying Yan +2
Population transfer via chirped rapid adiabatic passage is studied using open quantum and semiclassical models, with and without the rotating-wave approximation. A time-dependent v…
Quantum Resource Theories beyond Convexity
Roberto Salazar, Jakub Czartowski, Ricard Ravell RodrÃguez +3
A class of quantum resource theories, based on non-convex star-shape sets, presented in this work captures the key quantum properties that cannot be studied by standard convex theo…
Uncertainty-disturbance relations and applications
Liang-Liang Sun, Kishor Bharti, Xiang Zhou +3
Uncertainty and intrinsic measurement disturbance, two fundamental concepts in quantum measurement, have conventionally been viewed as distinct and studied separately. In this work…
Loop Quantum Photonic Chip for Coherent Multi-Time-Step Evolution
Yuancheng Zhan, Hui Zhang, Rebecca Erbanni +7
Quantum evolution is crucial for the understanding of complex quantum systems. However, current implementations of time evolution on quantum photonic platforms are limited by both…
Generalized Numerical Framework for Improved Finite-Sized Key Rates with Rényi Entropy
Rebecca R. B. Chung, Nelly H. Y. Ng, Yu Cai
Quantum key distribution requires tight and reliable bounds on the secret key rate to ensure robust security. This is particularly so for the regime of finite block sizes, where th…
