Thermal States as Universal Resources for Quantum Computation with Always-On Interactions
Thermal States as Universal Resources for Quantum Computation with Always-On Interactions
Measurement-based quantum computation utilizes an initial entangled resource state and proceeds with subsequent single-qubit measurements. It is implicitly assumed that the interactions between qubits can be switched off so that the dynamics of the measured qubits do not affect the computation. By proposing a model spin Hamiltonian, we demonstrate that …
