### Quantum Computers

By using an electron-beam ion trap, Thomas Schenkel and T.C. Shen of the Accelerator and Fusion Research Division are trying to develop a quantum computer that uses single electrons as 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 has a 3 bits, it can have one of the 8 following possible states: 000, 001, 010, 100, 011, 101, 110, 111. A quantum computer on the other hand 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. Therefore, if a quantum computer that is made of 50 qubits is made, the number of possible states is greater than 10
^{15}states. - Learn about the advancements of Quantum Computers and Moore's Law below:
