Tomography of a displacement photon counter for discrimination of single-rail optical qubits
Shuro Izumi, Jonas S. Neergaard-Nielsen, Ulrik L. Andersen
We investigate the performance of a Kennedy receiver, which is known as a beneficial tool in optical coherent communications, to the quantum state discrimination of the two superpo…
Fundamental precision limit of a Mach-Zehnder interferometric sensor when one of the inputs is the vacuum
Masahiro Takeoka, Kaushik P. Seshadreesan, Chenglong You +2
In the lore of quantum metrology, one often hears (or reads) the following no-go theorem: If you put vacuum into one input port of a balanced Mach-Zehnder Interferometer, then no m…
Projective measurement onto arbitrary superposition of coherent state bases
Shuro Izumi, Masahiro Takeoka, Kentaro Wakui +3
One of the peculiar features in quantum mechanics is that a superposition of macroscopically distinct states can exits. In optical system, this is highlighted by a superposition of…
