Selective writing and read-out of a register of static qubits
A. De Pasquale, F. Ciccarello, K. Yuasa +1
We propose a setup comprising an arbitrarily large array of static qubits (SQs), which interact with a flying qubit (FQ). The SQs work as a quantum register, which can be written o…
Thermodynamics of discrete quantum processes
Janet Anders, Vittorio Giovannetti
We define thermodynamic configurations and identify two primitives of discrete quantum processes between configurations for which heat and work can be defined in a natural way. Thi…
Electromagnetic channel capacity for practical purposes
Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone +1
We give analytic upper bounds to the channel capacity C for transmission of classical information in electromagnetic channels (bosonic channels with thermal noise). In the practica…
Ergodic and Mixing Quantum Channels in Finite Dimensions
Daniel Burgarth, Giulio Chiribella, Vittorio Giovannetti +2
The paper provides a systematic characterization of quantum ergodic and mixing channels in finite dimensions and a discussion of their structural properties. In particular, we disc…
Quantum channels and memory effects
F. Caruso, V. Giovannetti, C. Lupo +1
Any physical process can be represented as a quantum channel mapping an initial state to a final state. Hence it can be characterized from the point of view of communication theory…
Matrix Product State representation for Slater Determinants and Configuration Interaction States
Pietro Silvi, Davide Rossini, Rosario Fazio +2
Slater determinants are product states of filled quantum fermionic orbitals. When they are expressed in a configuration space basis chosen a priori, their entanglement is bound and…
