WebJul 24, 2024 · We show that every finite-dimensional quantum system with Markovian (i.e. GKLS-generated) time evolution has an autonomous unitary dilation which can be dynamically decoupled. Since there is also always an autonomous unitary dilation which cannot be dynamically decoupled, this highlights the role of dilations in the control of … WebApr 13, 2024 · Given a noisy quantum channel, we fully characterize the range of recoverable classical information.

It is well known that a quantum circuit on N N qubits composed of Clifford gates with the addition of k k non Clifford gates can be simulated on a classical computer by an algorithm scaling as poly(N)exp(k) poly ( N) exp ( k) [ 1 ].
