![]() This is the ability of two quantum particles (such as one photon split into two) to become connected and form a "system." The system pair can retain the specific correlations of the individual particles (such as a positive or negative spin in their energy states, which can translate into 0 or 1), even when physically separated. Fortunately, quantum teleportation does not enable faster than light communication, because to complete the teleportation Alice must transmit her measurement result to Bob over a. This characteristic as well as quantum interference (similar to how waves can amplify or "interfere" with each other) are fundamental to how quantum computers can potentially achieve exponential increases in computing power. This would be rather peculiar because the theory of relativity implies that faster than light information transfer could be used to send information backward in time. ![]() That turns out to be the equivalent of 0, 1, or both simultaneously, rather than just 0 or 1, as in a digital computer. According to the University of Copenhagen (UCPH), one of the institutions involved in the study, a quantum mechanical entanglement is a phenomenon with two light sources affect each other instantly and potentially across large geographic distances. HOWEVER what I’m suggesting is that we don’t. A quantum bit or "qubit" can behave as a wave as well as a discrete particle and exist in "super-positions" of states. Most if not all of the theories online negate being able to use quantum entanglement as a form of communication between two points in space because one simply can’t a)alter the particle b)predict its outcome c) predict the outcome of the opposite particle. What quantum entanglement changes is that if we measure the state of one particle of the entangled pair we instantly have information about the state of the. ![]() The same two physical phenomena that inspired quantum computing motivate quantum communications. 11 How did we get from quantum computing to quantum communications, and what is the business potential? 12 In fact, the 2022 Nobel Prize in Physics was awarded last October to three scientists for their experiments proving the reality of quantum entanglement, which is fundamental to quantum cryptography and secure communications. But another application of quantum mechanics that has attracted increasing attention is quantum communications. Quantum computing has been slowly progressing both as a technology and potential new platform business (see my previous column, "The Business of Quantum Computing," Communications, Oct.
