Extracting vacuum expectation values from approximate vacuum prepared by the adiabatic quantum computation

Kazuto Oshima

We propose a procedure to extract vacuum expectation values from approximate vacuum prepared by the adiabatic quantum computation. We use plural ancilla bits with hierarchical stru…

Improving approximate vacuum prepared by the adiabatic quantum computation

Kazuto Oshima

According to the quantum adiabatic theorem, we can in principle obtain a true vacuum of a quantum system starting from a trivial vacuum of a simple Hamiltonian. In actual adiabatic…

Remark on using quantum states prepared by the adiabatic quantum computation

Kazuto Oshima

We indicate that there are points to keep in mind in utilizing quantum states prepared by the adiabatic quantum computation. Even if an instantaneous expectation value of a physica…

Channel fidelities for high-fidelity approach in KLM scheme

Kazuto Oshima

We study channel fidelity for the high-fidelity approach in the Knill-Laflamme-Milburn (KLM) scheme. We examine an optimal channel fidelity and identify the corresponding…

Lower Bounds of Success Probabilities for High-Fidelity Approach in KLM Scheme

Kazuto Oshima

In the Knill-Laflamme-Milburn (KLM) scheme, the success probability of quantum teleportation is given by , wehre is the number of the ancilla qubits. For the hi…

Simple procedure for classical signal-procession in cluster-state quantum computation

Kazuto Oshima

We exhibit a simple procedure to find how classical signals should be processed in cluster-state quantum computation. Using stabilizers characterizing a cluster state, we can easil…
