As cellular phones become more popular, there have been plans to release cell phone numbers into public 411 and reverse number directories via a separate Wireless telephone directory. However, these plans have come under opposition from internet based privacy advocate groups, and blogs, often citing privacy concerns.
Conversely, publishers note that phone book directories are 100% recyclable and are made using soy-based and non-toxic inks, glues, and dyes. [ 21 ] In 2011, San Francisco became the first city in the United States to restrict yellow page distribution to people who opt in, [ 22 ] but was being sued in federal court by the Local Search ...

Quantum key distribution (QKD) is a secure communication method that implements a cryptographic protocol involving components of quantum mechanics.It enables two parties to produce a shared random secret key known only to them, which then can be used to encrypt and decrypt messages.
Quantum information is the information of the state of a quantum system. It is the basic entity of study in quantum information theory, [1] [2] [3] and can be manipulated using quantum information processing techniques. Quantum information refers to both the technical definition in terms of Von Neumann entropy and the general computational term.
In quantum computing, Grover's algorithm, also known as the quantum search algorithm, is a quantum algorithm for unstructured search that finds with high probability the unique input to a black box function that produces a particular output value, using just () evaluations of the function, where is the size of the function's domain.
Quantum mechanics is a fundamental theory that describes the behavior of nature at and below the scale of atoms. [2]: 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science. Quantum mechanics can describe many systems that classical physics cannot.
