This is where quantum states replace binary ones and zeros, enabling a computing paradigm that promises to answer otherwise impossible questions. For quantum computing, cold is the new hot. The Quantum Advantage In quantum computing, a qubit (quantum bit) represents all possible states of that bit until its value is measured, at which point it collapses to either 0 or 1. This is of limited practical advantage for one qubit, but when a set of qubits becomes entangled, their states can become correlated thanks to what Einstein described as “spooky action at a distance.” Together, the qubits then represent all possible combinations of their individual states. Quantum gates can act on these qubits to perform computations on all possible states at once. Measurement then collapses the quantum system's state from a probabilistic superposition to a definite result.Quantum computation is expected to have advantages for tackling problems that are highly combinatorial and so have very large search or optimization spaces; strongly affected by quantum phenomena themselves, e.g., for simulations of chemical reactions or physical processes; or based on mathematical forms that have been specially developed to be addressable by quantum algorithms. Building Better Quantum ComputersThe challenge for implementing quantum computing is that it relies on being able to set, store, operate upon and re...
