One way quantum computation (1WQC) uses an initially highly entangled
state (called a cluster state), and then a pattern of single qubit
measurements along different directions, together with feed-forward
based on the results, in order to drive a quantum computation. The final
result of the computation is obtained by measuring the last remaining
qubits in the computational basis. 1WQC was introduced by Raussendorf
and Briegl in 2001 [1]. The key feature is that the computation is not
reversible since measurement "collapses" the state of the measured
qubit, effectively disentangling it from the rest of the cluster. The
essential concept underlying 1WQC is teleportation of quantum gates,
extending the idea behind linear optical QC.
The main advantage of 1WQC is that it allows scalable universal QC in
systems which have a probabilistic entangling procedure and single qubit
measurements, but without a direct two-qubit interaction suitable for
implementing deterministic entangling gates.
