By Mario Herrero-Valea

Of all the advances made in theoretical physics in the last twenty years, I still have no doubt that the most impressive one is the so called Maldacena’s conjecture, the guess that the physics involved in some models of quantum gravity living in a very concrete 5-dimensional spacetime has a one-to-one correspondence with the physics […]

PhysicsQuantum physics

By Daniel Manzano

Both thermodynamics and quantum mechanics are very important theories, but they are applicable to very different kinds of systems. Thermodynamics describes macroscopic systems where the number of particles is huge (around Avogadro’s number: 6.022×1023). On the other hand, quantum mechanics describes the behavior of microscopic particles. The regimes where these two theories can be applied […]

Quantum mechanics and relativity constitute the two main revolutions in physics on the twentieth century. Furthermore, the counterintuitive character of quantum mechanics yields to a rich branch of different possible interpretations, and there are still many open questions. Not solving, but just defining these questions, was the main purpose of a conference entitled “Quantum physics […]

Entanglement is a fundamental tool in quantum computing and several quantum information protocols, such as quantum teleportation, quantum cryptography and quantum key distribution. The basic unit of entanglement is the entangled bit (ebit), represented by a maximally entangled state of two qubits (quantum bits). Entanglement can also be implemented in a higher dimensional Hilbert space […]
