Query: Estimating Quantum and Private capacities of Gaussian channels via
  degradable extensions   We present upper bounds on the quantum and private capacity of single-mode,
phase-insentitive Bosonic Gaussian Channels based on degradable extensions. Our
findings are state-of-the-art in the following parameter regions: low
temperature and high transmissivity for the thermal attenuator, low temperature
for additive Gaussian noise, high temperature and intermediate amplification
for the thermal amplifier.
