Quantum cryptographic ranging
Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone
We present a system to measure the distance between two parties that allows only trusted people to access the result. The security of the protocol is guaranteed by the complementar…
The power of entangled quantum channels
Seth Lloyd
All communication channels are at bottom quantum mechanical. Quantum mechanics contributes both obstacles to communication in the form of noise, and opportunities in the use of int…
Computational capacity of the universe
Seth Lloyd
Merely by existing, all physical systems register information. And by evolving dynamically in time, they transform and process that information. The laws of physics determine the a…
Positioning and clock synchronization through entanglement
Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone
A method is proposed to employ entangled and squeezed light for determining the position of a party and for synchronizing distant clocks. An accuracy gain over analogous protocols…
Clock synchronization with dispersion cancellation
V. Giovannetti, S. Lloyd, L. Maccone +1
The dispersion cancellation feature of pulses which are entangled in frequency is employed to synchronize clocks of distant parties. The proposed protocol is insensitive to the pul…
Information-theoretic approach to the study of control systems
Hugo Touchette, Seth Lloyd
We propose an information-theoretic framework for analyzing control systems based on the close relationship of controllers to communication channels. A communication channel takes…
