Passive states as optimal inputs for single-jump lossy quantum channels
Giacomo De Palma, Andrea Mari, Seth Lloyd +1
The passive states of a quantum system minimize the average energy among all the states with a given spectrum. We prove that passive states are the optimal inputs of single-jump lo…

On the uncomputability of the spectral gap
Seth Lloyd
This paper reviews the 1994 proof that the spectral gap of Hamiltonian quantum systems capable of universal computation is uncomputable.
