Efficient capacity-achieving entanglement generation with application to pure-loss Bosonic channels
Avijit Mandal, Christophe Piveteau, Henry D. Pfister +1
While the ultimate limits on the rate of quantum communication over noisy channels are well-established, very few efficient coding schemes achieving these limits are known. This co…
Gibbs state preparation through quantum decoding
Christophe Piveteau, Yihui Quek, M. Isabel Franco Garrido
We propose a Gibbs state preparation algorithm that exploits algebraic structure in the Hamiltonian. Our starting point is Hamiltonian Decoded Quantum Interferometry (HDQI), a rece…
Quantum Message Passing Convergence and Vanishing Block-Error Probability for Random LDPC Codes
Avijit Mandal, Christophe Piveteau, Joseph M. Renes +1
Belief propagation with quantum messages (BPQM) is a quantum algorithm that decodes classical codes transmitted over classical--quantum channels. It realizes optimal decoding on tr…
