Signal detection without finite-energy limits to quantum resolution
We show that there are extremely simple signal detection schemes where the finiteness of energy resources places no limit to the resolution. On the contrary, larger resolution can be obtained with lower energy. To this end the generator of the signal-dependent transformation encoding the signal information on the probe state must be different from the energy. We show that the larger the deviati...
متن کاملPerformance Evaluation of Finite-Resolution IR-UWB Signal Detection
Finite-resolution digital receiver is considered to be a potential solution to meet the severe demand of ADC that results from wideband of IR-UWB signal. However, the quantized distortion is totally different from full-resolution quantized signal. In this paper, the finite-resolution quantized signal model is derived. Based on the correlation receiver, estimation and detection performance of fi...
متن کاملQuantum phase transitions without thermodynamic limits
A new microcanonical equilibrium state is introduced for quantum systems with finite-dimensional state spaces. Equilibrium is characterised by a uniform distribution on a level surface of the expectation value of the Hamiltonian. The distinguishing feature of the proposed equilibrium state is that the corresponding density of states is a continuous function of the energy, and hence thermodynami...
متن کاملOvercoming Resolution Limits in MDL Community Detection
A popular approach to community detection in networks is to search for partitions that maximize modularity [7]. However, recent work has identified two important limitations of modularity as a community quality criterion: a resolution limit; and a bias towards finding equal-sized communities. Compression-based approaches that search for partitions that minimize description length are a recent a...
متن کاملQuantum teleportation without irreversible detection.
Brief Reports are accounts of completed research which do not warrant regular articles or the priority handling given to Rapid Communications; however, the same standards of scientific quality apply. (Addenda are included in Brief Reports.) A Brief Report may be no longer than four printed pages and must be accompanied by an abstract. The same publication schedule as for regular articles is fol...
