Quantum-enhanced measurements: beating the standard quantum limit
Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone
Quantum mechanics, through the Heisenberg uncertainty principle, imposes limits to the precision of measurement. Conventional measurement techniques typically fail to reach these l…
Bosonic Memory Channels
Vittorio Giovannetti, Stefano Mancini
We discuss a Bosonic channel model with memory effects. It relies on a multi-mode squeezed (entangled) environment's state. The case of lossy Bosonic channels is analyzed in detail…
Efficient and perfect state transfer in quantum chains
Daniel Burgarth, Vittorio Giovannetti, Sougato Bose
We present a communication protocol for chains of permanently coupled qubits which achieves perfect quantum state transfer and which is efficient with respect to the number chains…
Conditions for the multiplicativity of maximal l_p-norms of channels for fixed integer p
Vittorio Giovannetti, Seth Lloyd, Mary Beth Ruskai
We introduce a condition for memoryless quantum channels which, when satisfied guarantees the multiplicativity of the maximal l_p-norm with p a fixed integer. By applying the condi…
Inequalities for quantum channels assisted by limited resources
Vittorio Giovannetti
The information capacities and ``distillability'' of a quantum channel are studied in the presence of auxiliary resources. These include prior entanglement shared between the sende…
Conveyor belt clock synchronization
Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone +2
A protocol for synchronizing distant clocks is proposed that does not rely on the arrival times of the signals which are exchanged, and an optical implementation based on coherent-…
