Quantum state decorrelation
Giacomo M. D'Ariano, Rafal Demkowicz-Dobrzanski, Paolo Perinotti +1
We address the general problem of removing correlations from quantum states while preserving local quantum information as much as possible. We provide a complete solution in the ca…
Quantum Hamilton-Jacobi Theory
Marco Roncadelli, L. S. Schulman
Quantum canonical transformations have attracted interest since the beginning of quantum theory. Based on their classical analogues, one would expect them to provide a powerful qua…
Complementarity of Private and Correctable Subsystems in Quantum Cryptography and Error Correction
Dennis Kretschmann, David W. Kribs, Robert W. Spekkens
We make an explicit connection between fundamental notions in quantum cryptography and quantum error correction. Error-correcting subsystems (and subspaces) for quantum channels ar…
Quantum Benchmark for Teleportation and Storage of Squeezed States
Gerardo Adesso, Giulio Chiribella
We provide a quantum benchmark for teleportation and storage of single-mode squeezed states with zero displacement and a completely unknown degree of squeezing along a given direct…
A Continuity Theorem for Stinespring's Dilation
Dennis Kretschmann, Dirk Schlingemann, Reinhard F. Werner
We show a continuity theorem for Stinespring's dilation: two completely positive maps between arbitrary C*-algebras are close in cb-norm iff we can find corresponding dilations tha…
Quantum random access memory
Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone
A random access memory (RAM) uses n bits to randomly address N=2^n distinct memory cells. A quantum random access memory (qRAM) uses n qubits to address any quantum superposition o…
Phase-covariant cloning of coherent states
Massimiliano F. Sacchi
We consider the problem of phase-covariant cloning for coherent states. We show that an experimental scheme based on ideal phase measurement and feedforward outperforms the semicla…
How continuous quantum measurements in finite dimension are actually discrete
G. Chiribella, G. M. D'Ariano, D. M. Schlingemann
We show that in finite dimension a quantum measurement with continuous set of outcomes is always equivalent to a continuous random choice of measurements with only finite outcomes.
Optimal estimation of ensemble averages from a quantum measurement
Paolo Perinotti, Giacomo M. D'Ariano
We consider the general measurement scenario in which the ensemble average of an operator is determined via suitable data-processing of the outcomes of a quantum measurement descri…
No-signaling, dynamical independence, and the local observability principle
Giacomo Mauro D'Ariano
Within a general operational framework I show that a-causality at a distance of "local actions" (the so-called "no-signaling") is a direct consequence of commutativity of local tra…
