Quantum superreplication of states and gates
Giulio Chiribella, Yuxiang Yang
While the no-cloning theorem forbids the perfect replication of quantum information, it is sometimes possible to produce large numbers of replicas with vanishingly small error. Thi…

Efficient Quantum Compression for Ensembles of Identically Prepared Mixed States
Yuxiang Yang, Giulio Chiribella, Daniel Ebler
We present one-shot compression protocols that optimally encode ensembles of identically prepared mixed states into qubits. In contrast to the case of pure-state en…

Optimal quantum operations at zero energy cost
Giulio Chiribella, Yuxiang Yang
Quantum technologies are developing powerful tools to generate and manipulate coherent superpositions of different energy levels. Envisaging a new generation of energy-efficient qu…
