In this article we consider flagged extensions of convex combination of quantum channels, and find general sufficient conditions for the degradability of the flagged extension. An immediate application is a bound on the quantum $Q$ and private $P$ capacities of any channel being a mixture of a unitary map and another channel, with the probability associated to the unitary component being larger than $1/2$. We then specialize our sufficient conditions to flagged Pauli channels, obtaining a family of upper bounds on quantum and private capacities of Pauli channels. In particular, we establish new state-of-the-art upper bounds on the quantum and private capacities of the depolarizing channel, BB84 channel and generalized amplitude damping channel. Moreover, the flagged construction can be naturally applied to tensor powers of channels with less restricting degradability conditions, suggesting that better upper bounds could be found by considering a larger number of channel uses.

Venture capital firm, Fundamental Labs launched its Fundamental Labs Fund V – the fifth in its  series of funds that kicked off in 2016. It was constituted within one month with a medium size of  $50M. Fundamental Labs’ investment philosophy is anchored around being a long-term, strategic,  value investor. Short-term speculation is not its approach so remains phase agnostic.
