UNBIASED COIN TOSSING WITH A BIASED COIN by
PrQcedures are exhibited and analyzed for converting a sequence of iid Bernoulli variables with unknown mean p into a Bernoulli variable with mean 1/2. The efficiency of several procedures is studied.
متن کاملTossing a Biased Coin
When we talk about a coin toss, we think of it as unbiased: with probability one-half it comes up heads, and with probability one-half it comes up tails. An ideal unbiased coin might not correctly model a real coin, which could be biased slightly one way or another. After all, real life is rarely fair. This possibility leads us to an interesting mathematical and computational question. Is there...
متن کاملOn the Number of Switches in Unbiased Coin-tossing
A biased coin is tossed n times independently and sequentially. A “head” switch is a tail followed by a head and a “tail” switch is a head followed by a tail. Joint Laplace transform for the number of “head” switches and “tail” switches are given. For the total number of switches, the central limit theorem and the large deviation principle are established.

متن کاملExperimental quantum coin tossing.
In this Letter we present the first implementation of a quantum coin-tossing protocol. This protocol belongs to a class of "two-party" cryptographic problems, where the communication partners distrust each other. As with a number of such two-party protocols, the best implementation of the quantum coin tossing requires qutrits, resulting in a higher security than using qubits. In this way, we ha...
