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…
Single-atom demonstration of quantum Landauer principle
L. L. Yan, T. P. Xiong, K. Rehan +7
One of the outstanding challenges to information processing is the eloquent suppression of energy consumption in execution of logic operations. Landauer principle sets an energy co…
Experimental verification of a Jarzynski-related information-theoretic equality using a single trapped ion
T. P. Xiong, L. L. Yan, F. Zhou +7
Most non-equilibrium processes in thermodynamics are quantified only by inequalities, however the Jarzynski relation presents a remarkably simple and general equality relating non-…
Reply to comment in arXiv:1802.01382
T. P. Xiong, L. L. Yan, F. Zhou +7
Here we respond to a comment [arXiv:1802.01382] submitted recently on 'Experimental Verification of a Jarzynski-Related Information-Theoretic Equality by a Single Trapped Ion' PRL…
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…
