Parametric two-qubit gates via Landau-Zener interference
Simon Geisert, Albert Hertel, Soeren Ihssen +23
We propose and demonstrate gates between two superconducting qubits based on quantum interference of consecutive Landau-Zener (LZ) transitions. This gate mechanism bridges between…
Neural networks for on-the-fly single-shot state classification
Rohit Navarathna, Tyler Jones, Tina Moghaddam +5
Neural networks have proven to be efficient for a number of practical applications ranging from image recognition to identifying phase transitions in quantum physics models. In thi…
Quantum rifling: protecting a qubit from measurement back-action
Daniel Szombati, Alejandro Gomez Frieiro, Clemens Müller +3
Quantum mechanics postulates that measuring the qubit's wave function results in its collapse, with the recorded discrete outcome designating the particular eigenstate that the qub…
Nonreciprocity realized with quantum nonlinearity
Andrés Rosario Hamann, Clemens Müller, Markus Jerger +6
Nonreciprocal devices are a key element for signal routing and noise isolation. Rapid development of quantum technologies has boosted the demand for a new generation of miniaturize…
Realization of a quantum random generator certified with the Kochen-Specker theorem
Anatoly Kulikov, Markus Jerger, Anton Potočnik +2
Random numbers are required for a variety of applications from secure communications to Monte-Carlo simulation. Yet randomness is an asymptotic property and no output string genera…
In situ characterization of qubit control lines: a qubit as a vector network analyzer
Markus Jerger, Anatoly Kulikov, Zénon Vasseli +1
We present a technique to measure the transfer function of a control line using a qubit as a vector network analyzer. Our method requires coupling the line under test to the the lo…
Quartz-superconductor quantum electromechanical system
M. J. Woolley, M. F. Emzir, G. J. Milburn +4
We propose and analyse a quantum electromechanical system composed of a monolithic quartz bulk acoustic wave (BAW) oscillator coupled to a superconducting transmon qubit via an int…
3D microwave cavity with magnetic flux control and enhanced quality factor
Yarema Reshitnyk, Markus Jerger, Arkady Fedorov
Three-dimensional (3D) superconducting microwave cavities with large mode volumes typically have high quality factors (). This is due to a reduced sensitivity to surface die…
Contextuality without nonlocality in a superconducting quantum system
Markus Jerger, Yarema Reshitnyk, Markus Oppliger +8
Classical realism demands that system properties exist independently of whether they are measured, while noncontextuality demands that the results of measurements do not depend on…
Realization of a binary-outcome projection measurement of a three-level superconducting quantum system
Markus Jerger, Pascal Macha, Andrés Rosario Hamann +3
Binary-outcome measurements allow to determine whether a multi-level quantum system is in a certain state while preserving quantum coherence between all orthogonal states. In this…
Anisotropic rare-earth spin ensemble strongly coupled to a superconducting resonator
S. Probst, H. Rotzinger, S. Wünsch +5
Interfacing photonic and solid-state qubits within a hybrid quantum architecture offers a promising route towards large scale distributed quantum computing. Ideal candidates for co…
Frequency Division Multiplexing Readout and Simultaneous Manipulation of an Array of Flux Qubits
Markus Jerger, Stefano Poletto, Pascal Macha +3
An important desired ingredient of superconducting quantum circuits is a readout scheme whose complexity does not increase with the number of qubits involved in the measurement. He…
