Abstracts:
The blind quantum computing protocols (BQC) enable a
classical client with limited quantum technology to delegate a
computation to the quantum server(s) in such a way that the privacy of
the computation is preserved. Here we present a new scheme for BQC that
uses the concept of the measurement based quantum computing with the
novel resource state of Affleck-Kennedy-Lieb-Tasaki (AKLT) chains
leading to more robust computation. AKLT states are physically motivated
resource as they are gapped ground states of a physically natural
Hamiltonian in condensed matter physics. Our BQC protocol can enjoy the
advantages of AKLT resource states (in a multiserver setup), such as the
cooling preparation of the resource state, the energy-gap protection of
the quantum computation. It also provides a simple and efficient
preparation of the resource state in linear optics with biphotons.
