Magic state
A special quantum resource that is consumed through magic state injection protocols to implement non-Clifford gate operations such as the T gate. It is a key resource for achieving universal quantum computation in fault-tolerant quantum computing.
Timeline (last 90 days)
A magic state is a non-stabilizer quantum state, and by combining it with Clifford gates through a magic state injection protocol, non-Clifford operations can be realized.
The cost of preparing magic states may account for 95% of a quantum computer's total computing power.
The magic state scheme first prepares magic states, then, through "magic state injection," a quantum gate teleportation protocol, consumes the magic states to implement the T gate, thereby bypassing the highly nonlinear physical processes required to implement the T gate directly.
