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 Circuits Architecture

Giulio Chiribella, Giacomo Mauro D'Ariano, Paolo Perinotti

We present a method for optimizing quantum circuits architecture. The method is based on the notion of "quantum comb", which describes a circuit board in which one can insert varia…

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…

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 indirect estimation theory and joint estimate of all moments of two incompatible observables

Giacomo Mauro D'Ariano, Paolo Perinotti, Massimiliano Federico Sacchi

We introduce the quantum indirect estimation theory, which provides a general framework to address the problem of which ensemble averages can be estimated by means of an available…

Quantum private queries

Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone

We propose a cheat sensitive quantum protocol to perform a private search on a classical database which is efficient in terms of communication complexity. It allows a user to retri…

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…

Optimal phase estimation in quantum networks

Wim van Dam, G. Mauro D'Ariano, Artur Ekert +2

We address the problem of estimating the phase phi given N copies of the phase rotation u(phi) within an array of quantum operations in finite dimensions. We first consider the spe…

Erasable and unerasable correlations

G. M. D'Ariano, R. Demkowicz-Dobrzanski, P. Perinotti +1

We address the problem of removing correlation from sets of states while preserving as much local quantum information as possible. We prove that states obtained from universal clon…
