Anthony Laing of the University of Bristol described the technique as a “nice way to generate random numbers as it makes use of technology already embedded in the phone”. However, he cautioned, “It might be
Quantum PhysicsOur aim is to experimentally study the possibility of distinguishing between quantum sources of randomness--recently proved to be theoretically incomputable--and some well-known computable sources of pseudo-randomness. Incomputability is a necessary, but not sufficient "symptom" of "true...
However, today's quantum computers operate at a much smaller scale than is theoretically possible, largely because their quantum properties are prone to collapse from interference by "noise," such as vibration or radiation. Thus, the current stage of quantum technology is callednoisy intermediate-sca...
which uses quantum mechanics to securely exchange encryption keys. Data encrypted via QKD creates a random quantum state that is difficult to copy. Many QKD protocols can also detect eavesdroppers. The National Security Agency, however, has stated this option isnot viable on its ownas it now s...
Generative Adversarial Networks (GAN) show excellent performance in various problems of computer vision, computer graphics, and machine learning, but requi
The most common way of constructing a hash function (e.g., SHA-1) is to iterate a compression function on the input message. The compression function is usually designed from scratch or made out of a block-cipher. In this paper, we introduce a new security notion for hash-functions, str...
learning abilities. These models, while powerful, struggle with representing higher-order cognitive functions and abstract reasoning. Chella and Manzotti (2007) emphasizes that while neural networks exhibit pattern recognition and learning capabilities, they lack the understanding intrinsic to conscious experie...
(For the record, the thing that makes them deflect is called the Lorentz force, but we don't need to go into all the details here.) That means one side of the material will see more electrons than the other, so a potential difference (voltage) will appear across the material at right...
to cause chemical damage to these proteins during the time course of the experiments. Some experiments were performed in triplicate suggesting random experimental errors, such as sticking of proteins to the plastic tips, tube walls or cuvette walls, should average out....
For it to be unitary, we need Rai j R b ij = δabδC D, Rai j Rakl = δki δlj C a∈C a ∈ C, b ∈ D (3.5) (3.6) Note that the second line involves the sum over all representa- tions present. From the above, it is clear that we can construct these matrices from ...
