Quantum computers, computer systems that leverage the laws of quantum mechanics, store and process information using qubits (i.e., quantum bits). In many quantum computers, qubits are linked via entanglement, a quantum mechanical effect that connects particles in such a way that their shared state cannot be described as separate, independent states.
One key objective of quantum scientists is to realize entanglement between large groups of qubits. This could ultimately help to develop increasingly powerful and sophisticated quantum computers that can tackle complex optimization and computational problems.
