Single-Atom Verification of the Information-Theoretical Bound of Irreversibility at the Quantum Level
J. W. Zhang, K. Rehan, M. Li +6
Quantitative measure of disorder or randomness based on the entropy production characterizes thermodynamical irreversibility, which is relevant to the conventional second law of th…
Single-qubit measurement of Heisenberg uncertainty lower bounds for three incompatible observables
K. Rehan, T. P. Xiong, L. -L. Yan +6
Being one of the centroidal concepts in quantum theory, the fundamental constraint imposed by Heisenberg uncertainty relations has always been a subject of immense attention and ch…
Ion-crystal demonstration of structural phase transition induced solely by temperature
J. Li, L. L. Yan, L. Chen +5
We demonstrate for the first time a linear-zigzag phase transition induced solely by temperature of the Ca ion crystals in a surface-electrode trap. In contrast to the…
Optimal joint measurements of complementary observables by a single trapped ion
T. P. Xiong, L. L. Yan, Z. H. Ma +5
The uncertainty relations, pioneered by Werner Heisenberg nearly 90 years ago, set a fundamental limitation on the joint measurability of complementary observables. This limitation…
