Characterization and tomography of a hidden qubit
M. Pechal, G. Salis, M. Ganzhorn +3
In circuit-based quantum computing, the available gate set typically consists of single-qubit gates acting on each individual qubit and at least one entangling gate between pairs o…

Exploring the Effect of Noise on the Berry Phase
S. Berger, M. Pechal, A. A. Abdumalikov +5
We make use of a superconducting qubit to study the effects of noise on adiabatic geometric phases. The state of the system, an effective spin one-half particle, is adiabatically g…

Geometric phases in superconducting qubits beyond the two-level-approximation
S. Berger, M. Pechal, S. Pugnetti +5
Geometric phases, which accompany the evolution of a quantum system and depend only on its trajectory in state space, are commonly studied in two-level systems. Here, however, we s…
