Quantum computational tensor network on string-net condensate
Tomoyuki Morimae
The string-net condensate is a new class of materials which exhibits the quantum topological order. In order to answer the important question, "how useful is the string-net condens…
Entanglement-fidelity relations for inaccurate ancilla-driven quantum computation
Tomoyuki Morimae, Jonas Kahn
It was shown in [T. Morimae, Phys. Rev. A {\bf81}, 060307(R) (2010)] that the gate fidelity of an inaccurate one-way quantum computation is upper bounded by a decreasing function o…
Ground state blind quantum computation on AKLT state
Tomoyuki Morimae, Vedran Dunjko, Elham Kashefi
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 priv…
How to upload a physical state to the correlation space
Tomoyuki Morimae
In the framework of the computational tensor network [D. Gross and J. Eisert, Phys. Rev. Lett. {\bf98}, 220503 (2007)], the quantum computation is performed in a virtual linear spa…
Strong entanglement causes low gate fidelity in inaccurate one-way quantum computation
Tomoyuki Morimae
We study how entanglement among the register qubits affects the gate fidelity in the one-way quantum computation if a measurement is inaccurate. We derive an inequality which shows…
Vacuum entanglement governs the bosonic character of magnons
Tomoyuki Morimae
It is well known that magnons, elementary excitations in a magnetic material, behave as bosons when their density is low. We study how the bosonic character of magnons is governed…
