Quantum Teleportation
A qubit transmitted from one location to another
Quantum teleportation is closely related to entanglement of quantum systems. It may be defined as a process by which a qubit (the basic unit of quantum information) can be transmitted from one location to another, without the qubit actually being transmitted through space. It is useful for quantum information processing and quantum communication. As with entanglement, it is applicable to simple and more complex quantum systems such as atoms and molecules. Recent research demonstrated quantum teleportation between atomic systems over long distances.
Quantum Information Processing (QIP) revolves around harnessing the principles of quantum mechanics for data processing and computing tasks. Unlike traditional digital computers that rely on bits, which can be either 0 or 1, quantum computers use qubits. These qubits can exist in multiple states at once, a phenomenon known as superposition. Qubits can be realized using atoms, ions, photons, or electrons, paired with devices to control them, forming both memory and processing components of a computer.
The simultaneous multi-state nature of qubits offers quantum computers inherent parallelism. This allows them to potentially solve specific problems, such as integer factorization or simulating quantum systems, exponentially faster than classical computers.
However, the field of quantum computing is still nascent. A pivotal advancement is the introduction of the QSAT Quantum Mesh Network, which leverages quantum concepts like superposition and entanglement, setting the stage for the next computing revolution.
