Warp-Drive Quantum Computation
Mikio Nakahara, Juha J. Vartiainen, Yasushi Kondo +2
Recently it has been shown that time-optimal quantum computation is attained by using the Cartan decomposition of a unitary matrix. We extend this approach by noting that the unita…
Demonstrating quantum algorithm acceleration with NMR quantum computer
Mikio Nakahara, Yasushi Kondo, Kazuya Hata +1
In general, a quantum circuit is constructed with elementary gates, such as one-qubit gates and CNOT gates. It is possible, however, to speed up the execution time of a given circu…
Exact solutions of the isoholonomic problem and the optimal control problem in holonomic quantum computation
Shogo Tanimura, Mikio Nakahara, Daisuke Hayashi
The isoholonomic problem in a homogeneous bundle is formulated and solved exactly. The problem takes a form of a boundary value problem of a variational equation. The solution is a…
