Measurement-Based Quantum Computation on Two-Body Interacting Qubits with Adiabatic Evolution

Measurement-Based Quantum Computation on Two-Body Interacting Qubits with Adiabatic Evolution

A cluster state cannot be a unique ground state of a two-body interacting Hamiltonian. Here, we propose the creation of a cluster state of logical qubits encoded in spin-1/2 particles by adiabatically weakening two-body interactions. The proposal is valid for any spatial dimensional cluster states. Errors induced by thermal fluctuations …
