Gate teleportation for device-scale quantum computing

  • It uses an entangled state, or a pair of messengers, to teleport a logic gate, which executes the operation in much the same way a qubit is teleported.
  • The messengers are entangled beforehand, and each one travels to a qubit and ropes it into the entangled state.
  • A measurement of M1’s spin, with a possible rotation on M2 depending on the outcome, leaves B1 and M2 entangled.
