Quantum Fisher Information with Coherence
Zdeněk Hradil, Jaroslav Řeháček, Luis Sánchez-Soto +1
In recent proposals for achieving optical super-resolution, variants of the Quantum Fisher Information (QFI) quantify the attainable precision. We find that claims about a strong e…
User-specified random sampling of quantum channels and its applications
Jun Yan Sim, Jun Suzuki, Berthold-Georg Englert +1
Random samples of quantum channels have many applications in quantum information processing tasks. Due to the Choi--Jamiołkowski isomorphism, there is a well-known correspondence b…
Proper error bars for self-calibrating quantum tomography
Jun Yan Sim, Jiangwei Shang, Hui Khoon Ng +1
Self-calibrating quantum state tomography aims at reconstructing the unknown quantum state and certain properties of the measurement devices from the same data. Since the estimates…
Reply to "Comment on `Past of a quantum particle revisited' "
Berthold-Georg Englert, Kelvin Horia, Jibo Dai +2
We stand by our findings in Phys. Rev A. 96, 022126 (2017). In addition to refuting the invalid objections raised by Peleg and Vaidman, we report a retrocausation problem inherent…
