Observation of two-orbital spin-exchange interactions with ultracold SU(N)-symmetric fermions
F. Scazza, C. Hofrichter, M. Höfer +3
We report on the direct observation of spin-exchanging interactions in a two-orbital SU(N)-symmetric quantum gas of ytterbium in an optical lattice. The two orbital states are repr…
Partial-measurement back-action and non-classical weak values in a superconducting circuit
J. P. Groen, D. Ristè, L. Tornberg +5
We realize indirect partial measurement of a transmon qubit in circuit quantum electrodynamics by interaction with an ancilla qubit and projective ancilla measurement with a dedica…
Probing quantum coherence in qubit arrays
J. Almeida, P. C. de Groot, S. F. Huelga +2
We discuss how the observation of population localization effects in periodically driven systems can be used to quantify the presence of quantum coherence in interacting qubit arra…
Speed limits for quantum gates in multi-qubit systems
S. Ashhab, P. C. de Groot, Franco Nori
We use analytical and numerical calculations to obtain speed limits for various unitary quantum operations in multiqubit systems under typical experimental conditions. The operatio…
Selective darkening of degenerate transitions for implementing quantum controlled-NOT gates
P. C. de Groot, S. Ashhab, A. Lupascu +4
We present a theoretical analysis of the selective darkening method for implementing quantum controlled-NOT (CNOT) gates. This method, which we recently proposed and demonstrated,…
Selective darkening of degenerate transitions demonstrated with two superconducting quantum bits
P. C. de Groot, J. Lisenfeld, R. N. Schouten +4
Controlled manipulation of quantum states is central to studying natural and artificial quantum systems. If a quantum system consists of interacting sub-units, the nature of the co…
