Hamiltonian of Homonucleus Molecules for NMR Quantum Computing
Yasushi Kondo, Mikio Nakahara, Kazuya Hata +1
We derive the Hamiltonian in the rotating frame for NMR quantum computing with homonucleus molecules as its computational resource. The Hamiltonian thus obtained is different from…
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…
Topological Vortex Formation in BEC under Gravitational Field
Yuki Kawaguchi, Mikio Nakahara, Tetsuo Ohmi
Topological phase imprinting is a unique technique for vortex formation in a Bose-Einstein condensate (BEC) of alkali metal gas, in that it does not involve rotation: BEC is trappe…
Acceleration of quantum algorithms using three-qubit gates
Juha J. Vartiainen, Antti O. Niskanen, Mikio Nakahara +1
Quantum-circuit optimization is essential for any practical realization of quantum computation, in order to beat decoherence. We present a scheme for implementing the final stage i…
