Photon Added Coherent States: Nondeterministic, Noiseless Amplification in Quantum Metrology
Bryan T. Gard, Dong Li, Chenglong You +13
Probabilistic amplification through photon addition, at the output of an Mach-Zehnder interferometer is discussed for a coherent input state. When a metric of signal to noise ratio…
Towards practical device-independent quantum key distribution with spontaneous parametric downconversion sources, on-off photodetectors and entanglement swapping
Kaushik P. Seshadreesan, Masahiro Takeoka, Masahide Sasaki
Device-independent quantum key distribution (DIQKD) guarantees unconditional security of secret key without making assumptions about the internal workings of the devices used. It d…
Unconstrained distillation capacities of a pure-loss bosonic broadcast channel
Masahiro Takeoka, Kaushik P. Seshadreesan, Mark M. Wilde
Bosonic channels are important in practice as they form a simple model for free-space or fiber-optic communication. Here we consider a single-sender two-receiver pure-loss bosonic…
