Quantum Information and Space - Time Akio Hosoya
A pedestrian description of possible connection between quantum information theory and relativity theory is given. I picked up topics of synchronization by entanglement and causality of completely positive maps in special relativity, while the problems of information loss in the black hole evaporation and the possible quantum state at the space-like singularities are briefly touched upon in gen...
متن کاملQuantum Information in Space and Time
Many important results in modern quantum information theory have been obtained for an idealized situation when the spacetime dependence of quantum phenomena is neglected. However the transmission and processing of (quantum) information is a physical process in spacetime. Therefore such basic notions in quantum information theory as the notions of composite systems, entangled states and the chan...
متن کاملQ-deformation, discrete time and quantum information as fiber space
In this paper we show the connection between the q-deformation and discrete time, starting from the q-deformed Heisenberg uncertainty relation and q-deformation calculus. We show that time has discrete nature and for this case we construct the connection between quantum information and spacetime via fiber space structure. 1 Heisenberg uncertainty relation, q-deformation and discretization of sp...
متن کاملTowards Quantum Information Theory in Space and Time
Modern quantum information theory deals with an idealized situation when the spacetime dependence of quantum phenomena is neglected. However the transmission and processing of (quantum) information is a physical process in spacetime. Therefore such basic notions in quantum information theory as qubit, channel, composite systems and entangled states should be formulated in space and time. In par...
متن کاملQuantum Space-Time and Tetrads1
The description of space-time in a quantum theoretical framework must be considered as a fundamental problem in physics. Most attempts start with an already given classical spacetime then the quantization is done. In contrast to this the central assumption in this paper is not to start with space-time, but to derive it from some more abstract presuppositions like this is done in von Weizsäcker’...
