The Accelerator and Fusion Research Division at Berkely Lab is trying to develop a quantum computer that utilizes single-electron based transistors.
Amazing But True
- To show how powerful a quantum computer is in comparison to a regular computer, we have to compare bits to qubits (quantum bits). If a classical computer uses a three bit register, it can only have one of the eight following states: 000, 001, 010, 100, 011, 101, 110, 111. On the other hand, a quantum computer can be in all of the above possible states at the same time. This implies that the number of possible states for a qubit is 2N, where N is the number of qubits. If 50 qubits are used, a superposition of 250 states is possible, translating to a machine that can process 250 steps in the time it takes the classical computer to take one.

- If you had 3 qubits, how many possible states could you have at once if each bit itself could be 1 or 0?
- What is Moore's law and why is it important?
- What is quantum superposition of states?
