Versatile microwave-driven trapped ion spin system for quantum information processing
Ch. Piltz, Th. Sriarunothai, S. Ivanov +2
Using trapped atomic ions we demonstrate a tailored and versatile effective spin-system suitable for quantum simulations and universal quantum computation. By simply applying micro…
Efficient construction of three- and four-qubit quantum gates by global entangling gates
Svetoslav S. Ivanov, Peter A. Ivanov, Nikolay V. Vitanov
We present improved circuits for the control-control-phase (Toffoli) gate and the control-swap (Fredkin) gate using three and four global two-qubit gates, respectively. This is a n…
Simplified implementation of the quantum Fourier transform with Ising-type Hamiltonians: Example with ion traps
Svetoslav S. Ivanov, Michael Johanning, Christof Wunderlich
We propose a simplified mathematical construction of the quantum Fourier transform which is suited for systems described by Ising-type Hamiltonians. By contrast to the standard Coo…
Composite two-qubit gates
Svetoslav S. Ivanov, Nikolay V. Vitanov
We design composite controlled-phase gates, which compensate errors in the phase of a single gate. The errors can be of various nature, such as relative, absolute or both. We prese…
