Quantum coin flipping
The previous post showed that quantum networks can be as interesting as quantum computers. The main difference from classical networks is the ability to transmit qubits instead of classical bits. This post explores another interesting problem in network communication: Coin flipping.
Quantum cryptography
In the previous post, I presented some computational problems that can be solved more efficiently by quantum computers. Today, however, computers are not only used for computations but also for solving various types of problems. In fact, most computer applications today perform minimal computation and primarily store, transfer, and transform data. Are there any non-computational problems that are difficult for classical computers but can be solved efficiently by quantum computers? In following posts, I will present examples of such problems in the field of computer networks.
