Two measurement bases are asymptotically informationally complete for any pure state tomography
Tianfeng Feng, Tianqi Xiao, Yu Wang +6
One of the fundamental questions in quantum information theory is to find how many measurement bases are required to obtain the full information of a quantum state. While a minimum…

Quantum observables over time for information recovery
Gabriele Bressanini, Farhan Hanif, Hyukjoon Kwon +1
We introduce the concept of quantum observables over time (QOOT), an operator that jointly describes two observables at two distinct time points, as a dual of the quantum state ove…
