(4,1)-Quantum random access coding does not exist—one qubit is not enough to recover one of four bits
An (n, 1, p)-quantum random access (QRA) coding, introduced by Ambainis et al (1999 ACM Symp. Theory of Computing p 376), is the following communication system: the sender which has n-bit information encodes his/her information into one qubit, which is sent to the receiver. The receiver can recover any one bit of the original n bits correctly with probability at least p, through a certain decod...
متن کاملOne is not enough.
In both prokaryotic and eukaryotic organisms, repressors and activators are responsible for regulating gene expression. The lac operon is a paradigm for understanding how metabolites function as signaling molecules and modulate transcription. These metabolites or allosteric effector molecules bind to the repressor and alter the conformational equilibrium between the induced and the repressed st...
متن کاملThe quantum does not reduce to discrete bits
There is no way to reduce physics to information theory. Matter is not just empty space with isolated bits of information. The quantum is not digital data, logic, probability, or information. There is a long history of trying to understand the ethereal mysteries of quantum mechanics by reduction to discrete information, as if the universe were a giant ghostly digital computer without the hardwa...
متن کاملWhen One Pipeline Is Not Enough
Pipelines that operate on buffers often work well to mitigate the high latency inherent in interprocessor communication and in accessing data on disk. Running a single pipeline on each node works well when each pipeline stage consumes and produces data at the same rate. If a stage might consume data faster or slower than it produces data, a single pipeline becomes unwieldy. We describe how we h...
متن کاملWhen One Interactive System is Not Enough
The Art Institute of Chicago's pioneering development of public computer programs jump started with two fortuitous events. In 1987 the museum was asked to join a consortium of museum education directors from seven art museums whose main goal was to research and experiment with educational computer technology. Soon afterwards, the Art Institute became one of sixteen American institutions selecte...
