Units of rotational information
Yuxiang Yang, Giulio Chiribella, Qinheping Hu
Entanglement in angular momentum degrees of freedom is a precious resource for quantum metrology and control. Here we study the conversions of this resource, focusing on Bell pairs…
Quantum Stopwatch: How To Store Time in a Quantum Memory
Yuxiang Yang, Giulio Chiribella, Masahito Hayashi
Quantum mechanics imposes a fundamental tradeoff between the accuracy of time measurements and the size of the systems used as clocks. When the measurements of different time inter…
Compression for quantum population coding
Yuxiang Yang, Ge Bai, Giulio Chiribella +1
We study the compression of n quantum systems, each prepared in the same state belonging to a given parametric family of quantum states. For a family of states with f independent p…
