Unconstrained Capacities of Quantum Key Distribution and Entanglement Distillation for Pure-Loss Bosonic Broadcast Channels
Masahiro Takeoka, Kaushik P. Seshadreesan, Mark M. Wilde
We consider quantum key distribution (QKD) and entanglement distribution using a single-sender multiple-receiver pure-loss bosonic broadcast channel. We determine the unconstrained…
Renyi relative entropies of quantum Gaussian states
Kaushik P. Seshadreesan, Ludovico Lami, Mark M. Wilde
The quantum Renyi relative entropies play a prominent role in quantum information theory, finding applications in characterizing error exponents and strong converse exponents for q…
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…
