A family of degradable fermionic Gaussian channels
Quantum computing is the future. Or the present, if you believe that some real quantum computers are commercially available already. Because it is hard to admit that any computer system whose design and theoretical basis depend on quantum effects […]
The convergence of neuroscience and artificial intelligence
Several researchers in the field of artificial intelligence (AI) are warning about an AI winter, which means that scientists might lose the interest on the discipline, institutions reduce drastically the funding towards its research and lose presence in the public […]
Using machine learning to discover new metallic glasses
Metallic glasses are a unique class of materials whose properties combine some of the irreconcilable properties of both metals and polymers. They consist of a combination of metals which, in the solid state, present an amorphous atomic structure, in contrast […]
Your mind will never be uploaded to a computer
One of the most popular ideas within the new and fashionable transhumanism craze is that, in the future humans, will be able of reaching a kind of ‘immortality’ by decoding the information contained in your brain, ‘uploading’ it to […]
What does the “we don’t understand how artificial intelligence takes decisions” statement mean?
Specialized media sometimes publishes similar headlines to the title of the present article. For instance 1, 2, 3, 4, 5 or 6. They are all referred to deep learning, which is a part of artificial […]
Simulating particle physics in a quantum computer
Particle physics is an interesting and complicated field of study. Its theoretical framework, the Standard Model, was developed during the second half of the twentieth century and it opened he possibility to explaining the behavior of the basic blocks of […]
Negotiating Wi-Fi channels to improve bandwidth in surveillance networks
Security in residential and public areas is a matter of great importance for many people. This is why some Internet providers are offering surveillance systems as a value-added service. Such surveillance systems have recently shifted from CCTVs to IP-based cameras, […]
Semiconductor devices: Transistors (2) – Applications
Amplifying Voltage
If we place a large resistor in a circuit containing a transistor we can amplify the incoming voltage, since according to Ohm’s law voltage is equal to current times resistance. So a current crossing a small resistance corresponds […]
System of quadrotors for the transportation of deformable linear objects
Nowadays, the industry is centering their efforts on the development of single aerial robots carrying single objects, such as the widely-known drone of Amazon for delivering packages, which was followed by some national post-office services. However, other approaches go a […]
A working molecular electronic switch
A visionary perspective of molecular electronics is the use of single molecules as functional entities in electronic devices. In this context, some of the most important components are molecular switches, which are molecules that can be interconverted reversibly between at […]
