Can Qubit Errors Be Corrected?
This note examines assumptions at the basis of the recently proposed quantum error-correcting codes. It is shown that these codes can correct only a subset of errors, and are unable to correct small phase errors which can have disastrous consequences for a quantum computation. This shortcomings will restrict their usefulness in real applications. Colours seen by candle-light Will not look the s...

Error correction in the standard meaning of the term implies the ability to correct all small analog errors and some large errors. Examining assumptions at the basis of the recently proposed quantum error-correcting codes, it is pointed out that these codes can correct only a subset of errors, and are unable to correct small phase errors which can have disastrous consequences for a quantum comp...
متن کاملWhy Machines Cannot be
Mental processes are abstracted from a subset of the physical universe ; these, in turn, lead to the world of ideas. Although these ideas include quantum logic, no credible way has yet been found that constructs machines which use superimposed possibilities in the style of quantum logic, more general in computing power to machines based on classical logic. Machine theories are based exclusively...
متن کاملAggregating preferences cannot be fair
SOMMARIO/ABSTRACT Preferences typically define a partial ordering over outcomes. A number of formalisms like soft constraints and CP-nets exists to specify such partial or-derings. In situations involving multiple agents, we need to combine the preferences of several individuals. In this paper, we consider each agent as voting on whether they prefer one outcome to another. We prove that, under ...
متن کاملQuantum History Cannot Be Copied
We show that unitarity does not allow cloning of any two points in a ray. This has implication for cloning of the geometric phase information in a quantum state. In particular, the quantum history which is encoded in the geometric phase during cyclic evolution of a quantum system cannot be copied. We also prove that the generalized geometric phase information cannot be copied by a unitary opera...
