Strong converse rates for classical communication over thermal and additive noise bosonic channels
Bhaskar Roy Bardhan, Mark M. Wilde
We prove that several known upper bounds on the classical capacity of thermal and additive noise bosonic channels are actually strong converse rates. Our results strengthen the int…
Effects of Phase Fluctuations on Phase Sensitivity and Visibility of Path-Entangled Photon Fock States
Bhaskar Roy Bardhan, Kebei Jiang, Jonathan P. Dowling
We study effects of phase fluctuations on phase sensitivity and visibility of a class of robust path-entangled photon Fock states (known as mm' states) as compared to the maximally…
Dynamical decoupling with tailored waveplates for long distance communication using polarization qubits
Bhaskar Roy Bardhan, Katherine L. Brown, Jonathan P. Dowling
We address the issue of dephasing effects in flying polarization qubits propagating through optical fiber by using the method of dynamical decoupling. The control pulses are implem…
