Quantum evolution according to real clocks
We characterize good clocks, which are naturally subject to fluctuations, in statistical terms. We also obtain the master equation that governs the evolution of quantum systems according to these clocks and find its general solution. This master equation is diffusive and produces loss of coherence. Moreover, real clocks can be described in terms of effective interactions that are nonlocal in ti...
متن کاملCoherent State Approach to Quantum Clocks
The “problem of time” has been a pressing issue in quantum gravity for some time. To help understand this problem, Rovelli proposed a model of a two harmonic oscillators system where one of the oscillators can be thought of as a “clock” for the other oscillator thus giving a natural time reference frame for the system. Recently, the author has constructed an explicit form for the coherent state...
متن کاملA quantum network of clocks
The development of precise atomic clocks plays an increasingly important role in modern society. Shared timing information constitutes a key resource for navigation with a direct correspondence between timing accuracy and precision in applications such as the Global Positioning System. By combining precision metrology and quantum networks, we propose a quantum, cooperative protocol for operatin...
متن کاملQuantum Computers and Atomic Clocks
Recent developments in quantum information processing may be applicable to future atomic clocks. In this paper we discuss two potential applications to trappedion frequency standards. In the first, quantum-mechanical entanglement can provide a resource for increased measurement precision in spectroscopy. In the second, we indicate how a simultaneously trapped auxiliary ion species can be used t...
متن کاملTheory of Real Computation According to EGC
The Exact Geometric Computation (EGC) mode of computation has been developed over the last decade in response to the widespread problem of numerical non-robustness in geometric algorithms. Its technology has been encoded in libraries such as LEDA, CGAL and Core Library. The key feature of EGC is the necessity to decide zero in its computation. This paper addresses the problem of providing a fou...
