Qubits can be made from dif­fer­ent mate­ri­als, such as super­con­duc­tors or trapped ions.
Quan­tum com­put­ers use quan­tum bits (qubits). These bits are dif­fer­ent from stan­dard com­put­er bits, which can be either 0 or 1, as they can be both 0 and 1. These machines could be much faster than the fastest com­put­ers avail­able today as they would be able to com­pute with many qubits, result­ing in an expo­nen­tial increase in com­put­ing pow­er. Qubits can be made from dif­fer­ent mate­ri­als, such as super­con­duc­tors or trapped ions. Oth­er future meth­ods include pho­ton­ic quan­tum proces­sors that use light.
