... I find Aharonov’s proposal very problematic. It does remove action at a distance and randomness from basic physical interactions, two of the main difficulties with the collapse postulate. But it still has the third: it is not well defined. The backwards evolving quantum state needs to be tailored in ...

We have shown the most general case of Alice sending a qubit to the Bobs, but a special case would be where Alice could be a factory of pure states. MRAP could be used to send these ...

Some trends in the philosophy of physics - Philsci
... Philosophy of physics is about the interpretation and critical examination of physical theories and concepts. The interpretation part is typically concerned with the question of what understanding of Nature is provided by our best physical theories, e.g. is space-time absolute or relational, is matt ...
