Description
The standard method for implementing algorithms for quantum
computation is
through quantum circuits. Such circuits typically contain
quantum gates
involving more than a
single or two qubits. Multi-qubit gates can be decomposed
into 1- and
2-qubit gates, but this is not necessarily the most
efficient strategy. We
present a framework for quantum control directly at the
level of multiple
qubits. A concrete proposal employs a so-called Krawtchouk
qubit chain,
which has previously been studied and experimentally
realised in the
context of perfect state transfer.
