Activation of zero-error classical capacity in low-dimensional quantum systems
Jeonghoon Park, Jun Heo
Channel capacities of quantum channels can be nonadditive even if one of two quantum channels has no channel capacity. We call this phenomenon \emph{activation} of the channel capa…
Stability theorem of depolarizing channels for the minimal output quantum Rényi entropies
Eunok Bae, Gilad Gour, Soojoon Lee +2
We show that the stability theorem of the depolarizing channel holds for the output quantum -Rényi entropy for or , which is an extension of the well known case $…
Quantum non-signalling assisted zero-error classical capacity of qubit channels
Jeonghoon Park, Soojoon Lee
In this paper, we explicitly evaluate the one-shot quantum non-signalling assisted zero-error classical capacities $\M_0^{\mathrm{QNS}}$ for qubit channels. In particular, we show…
Zero-error classical capacity of qubit channels cannot be superactivated
Jeonghoon Park, Soojoon Lee
It was shown [T.S. Cubitt et al., IEEE Trans. Inform. Theory 57, 8114 (2011)] that there exist quantum channels where a single use cannot transmit classical information perfectly y…
Separable states to distribute entanglement
Jeonghoon Park, Soojoon Lee
It was shown that two distant particles can be entangled by sending a third particle never entangled with the other two [T. S. Cubitt et al., Phys. Rev. Lett. 91, 037902 (2003)]. I…
