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…
Multi-parameter quantum estimation of single- and two-mode pure Gaussian states
Gabriele Bressanini, Marco G. Genoni, M. S. Kim +1
We discuss the ultimate precision bounds on the multiparameter estimation of single- and two-mode pure Gaussian states. By leveraging on previous approaches that focused on the est…
Quantum error cancellation in photonic systems -- undoing photon losses
Adam Taylor, Gabriele Bressanini, Hyukjoon Kwon +1
Real photonic devices are subject to photon losses that can decohere quantum information encoded in the system. In the absence of full fault tolerance, quantum error mitigation tec…
