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…
Efficient and optimal quantum state discrimination via quantum belief propagation
Christophe Piveteau, Joseph M. Renes
We present an efficient quantum algorithm for a structured state discrimination problem we call the subspace decoding task. Building on this, we show that the algorithm enables eff…
Circuit cutting with classical side information
Christophe Piveteau, Lukas Schmitt, David Sutter
Circuit cutting is a technique for simulating large quantum circuits by partitioning them into smaller subcircuits, which can be executed on smaller quantum devices. The results fr…
Simulating quantum circuits with restricted quantum computers
Christophe Piveteau
It is one of the most fundamental objectives in quantum information science to understand the boundary between the computational power of classical and quantum computers. One possi…
