Probabilistic theories with purification

- G. Chiribella, G. D’Ariano, P. Perinotti
- Mathematics
- 11 August 2009

We investigate general probabilistic theories in which every mixed state has a purification, unique up to reversible channels on the purifying system. We show that the purification principle is… Expand

Theoretical framework for quantum networks

- G. Chiribella, G. D’Ariano, P. Perinotti
- Physics, Computer Science
- 28 April 2009

We present a framework to treat quantum networks and all possible transformations thereof, including as special cases all possible manipulations of quantum states, measurements, and channels, such… Expand

Informational derivation of quantum theory

- G. Chiribella, G. D’Ariano, P. Perinotti
- Philosophy
- 30 November 2010

We derive quantum theory from purely informational principles. Five elementary axioms - causality, perfect distinguishability, ideal compression, local distinguishability, and pure conditioning -… Expand

Transforming quantum operations: Quantum supermaps

- G. Chiribella, G. D’Ariano, P. Perinotti
- Physics
- 1 April 2008

We introduce the concept of quantum supermap, describing the most general transformation that maps an input quantum operation into an output quantum operation. Since quantum operations include as… Expand

Classical randomness in quantum measurements

- G. D’Ariano, P. Presti, P. Perinotti
- Mathematics
- 18 August 2004

Similarly to quantum states, also quantum measurements can be ‘mixed’, corresponding to a random choice within an ensemble of measuring apparatuses. Such mixing is equivalent to a sort of hidden… Expand

Quantum circuit architecture.

Maximum-likelihood estimation of the density matrix

- K. Banaszek, G. D’Ariano, M. Paris, M. Sacchi
- Mathematics
- 16 September 1999

We present a universal technique for quantum-state estimation based on the maximum-likelihood method. This approach provides a positive-definite estimate for the density matrix from a sequence of… Expand

Derivation of the Dirac Equation from Principles of Information Processing

- G. D’Ariano, P. Perinotti
- Physics
- 8 June 2013

Without using the relativity principle, we show how the Dirac equation in three space dimensions emerges from the large-scale dynamics of the minimal nontrivial quantum cellular automaton satisfying… Expand

Quantum tomography for measuring experimentally the matrix elements of an arbitrary quantum operation.
