A Classically-Based Theory of Impossible Worlds
a in the sense of ‘intensional’ that Yagisawa finds objectionable (i.e., having nonextensional identity conditions). On the present theory, though properties and relations are conceived intensionally (i.e., necessarily equivalent ones are distinguishable), they still have extensional identity conditions. It was noted in the first section of the paper that it is a consequence of our theory that ...
متن کاملClassically controlled quantum computation
It is reasonable to assume that quantum computations take place under the control of the classical world. For modeling this standard situation, we introduce a Classically-controlled Quantum Turing Machine (CQTM) which is a Turing machine with a quantum tape for acting on quantum data, and a classical transition function for a formalized classical control. In CQTM, unitary transformations and qu...

متن کاملDecoherence for classically chaotic quantum maps.
We study the behavior of an open quantum system, with an N-dimensional space of states, whose density matrix evolves according to a nonunitary map defined in two steps: A unitary step, where the system evolves with an evolution operator obtained by quantizing a classically chaotic map (baker's map and Harper's map are the two examples we consider). A nonunitary step where the evolution operator...
متن کاملImpossible Measurements on Quantum Fields*
It is shown that the attempt to extend the notion of ideal measurement to quantum field theory leads to a conflict with locality, because (for most observables) the state vector reduction associated with an ideal measurement acts to transmit information faster than light. Two examples of such information-transfer are given, first in the quantum mechanics of a pair of coupled subsystems, and the...
