Scientists have developed a microchip that can generate “qudits” that can assume 10 or more states, where qudits are the quantum bits used by quantum computers for zero and 1 in classical computers.  The super-positions that qubits can adopt let them each help perform two calculations at once. If two qubits are quantum-mechanically linked, they can help perform four calculations simultaneously; three qubits, eight calculations; and so on. As a result, a quantum computer with 300 qubits could perform more calculations in an instant than there are atoms in the known universe.
