Geometric quantum gates with superconducting qubits
I. Kamleitner, P. Solinas, C. Müller +2
We suggest a scheme to implement a universal set of non-Abelian geometric transformations for a single logical qubit composed of three superconducting transmon qubits coupled to a…
Splitting times of doubly quantized vortices in dilute Bose-Einstein condensates
J. A. M. Huhtamäki, M. Möttönen, T. Isoshima +2
Recently, the splitting of a topologically created doubly quantized vortex into two singly quantized vortices was experimentally investigated in dilute atomic cigar-shaped Bose-Ein…
High fidelity one-qubit operations under random telegraph noise
Mikko Mottonen, Rogerio de Sousa, Jun Zhang +1
We address the problem of implementing high fidelity one-qubit operations subject to time dependent noise in the qubit energy splitting. We show with explicit numerical results tha…
Decompositions of general quantum gates
M. Mottonen, J. J. Vartiainen
Quantum algorithms may be described by sequences of unitary transformations called quantum gates and measurements applied to the quantum register of n quantum bits, qubits. A colle…
Transformation of quantum states using uniformly controlled rotations
Mikko Mottonen, Juha J. Vartiainen, Ville Bergholm +1
We consider a unitary transformation which maps any given state of an -qubit quantum register into another one. This transformation has applications in the initialization of a q…
Quantum Circuits for General Multiqubit Gates
Mikko Mottonen, Juha J. Vartiainen, Ville Bergholm +1
We consider a generic elementary gate sequence which is needed to implement a general quantum gate acting on n qubits -- a unitary transformation with 4^n degrees of freedom. For s…
