Quantum capacity

In the theory of quantum communication, the quantum capacity is the highest rate at which quantum information can be communicated over many independent uses of a noisy quantum channel from a sender to a receiver. It is also equal to the highest rate at which entanglement can be generated over the channel, and forward classical communication cannot improve it. The quantum capacity theorem is important for the theory of quantum error correction, and more broadly for the theory of quantum computation. The theorem giving a lower bound on the quantum capacity of any channel is colloquially known as the LSD theorem, after the authors Lloyd, Shor, and Devetak who proved it with increasing standards of rigor.

Thermodynamics 6a - Heat Capacity and the Third Law I

In this video, we develop and discuss the final law of thermodynamics - the Third Law. We find that the Third Law is intimately connected with the concept of heat capacity, and fundamentally relies on the quantum-mechanical nature of matter. In this segment, we develop the Einstein Model f
