Random Error01:04

Random Error

848
Random or indeterminate errors originate from various uncontrollable variables, such as variations in environmental conditions, instrument imperfections, or the inherent variability of the phenomena being measured. Usually, these errors cannot be predicted, estimated, or characterized because their direction and magnitude often vary in magnitude and direction even during consecutive measurements. As a result, they are difficult to eliminate. However, the aggregate effect of these errors can be...

Wald-Wolfowitz Runs Test II01:17

Wald-Wolfowitz Runs Test II

193
The Wald-Wolfowitz runs test, commonly referred to as the runs test, is a nonparametric test used to assess the randomness of ordered data. The test evaluates the number of runs, which are consecutive sequences of similar elements within the data. If the number of runs is significantly higher or lower than expected, the data is considered non-random, indicating a detectable pattern or structure.
For binary data, runs are identified using symbols such as + and −, or equivalently, 1s and...

Random Sampling Method01:09

Random Sampling Method

11.0K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest. Among the various sampling methods used by...

Propagation of Uncertainty from Random Error00:59

Propagation of Uncertainty from Random Error

656
An experiment often consists of more than a single step. In this case, measurements at each step give rise to uncertainty. Because the measurements occur in successive steps, the uncertainty in one step necessarily contributes to that in the subsequent step. As we perform statistical analysis on these types of experiments, we must learn to account for the propagation of uncertainty from one step to the next. The propagation of uncertainty depends on the type of arithmetic operation performed on...

Random Variables

11.4K
A random variable is a single numerical value that indicates the outcome of a procedure. The concept of random variables is fundamental to the probability theory and was introduced by a Russian mathematician, Pafnuty Chebyshev, in the mid-nineteenth century.
Uppercase letters such as X or Y denote a random variable. Lowercase letters like x or y denote the value of a random variable. If X is a random variable, then X is written in words, and x is given as a number.
For example, let X = the...

Uncertainty in Measurement: Accuracy and Precision03:37

Uncertainty in Measurement: Accuracy and Precision

73.5K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Area of Science:

  • Quantum Information Science
  • Cryptography
  • Computer Science

Background:

  • Unpredictable random numbers are crucial for digital security and fair resource allocation.
  • Current random number generators (RNGs) have limitations in traceability, auditability, and certifiability of unpredictability.
  • Algorithmic RNGs are auditable but cannot guarantee a priori unpredictability, while device-independent quantum RNGs have vulnerable extraction steps.

Purpose of the Study:

  • To demonstrate a fully traceable random number generation protocol.
  • To address the limitations of existing RNGs by ensuring auditable and certifiable unpredictability.
  • To establish a public, traceable, and certifiable quantum randomness beacon.

Main Methods:

  • Developed a protocol based on device-independent quantum techniques.
  • Extracted randomness from unpredictable non-local quantum correlations.
  • Utilized distributed intertwined hash chains for cryptographic tracing and verification of randomness extraction.

Main Results:

  • Successfully demonstrated a fully traceable and certifiable random number generation protocol.
  • Launched a public quantum randomness beacon achieving a 99.7% success rate over 40 days.
  • Emitted 512 bits of traceable randomness per successful protocol run, certified to be uniform with a bounded error probability (2^-64).

Conclusions:

  • The protocol provides a public service for generating certifiable and traceable randomness.
  • This quantum approach offers an entanglement-derived advantage over classical methods for secure randomness generation.
  • The developed method enhances the trustworthiness and security of random number generation for critical applications.
