Losert, Merritt P. (author), Eriksson, M. A. (author), Joynt, Robert (author), Rahman, Rajib (author), Scappucci, G. (author), Coppersmith, Susan N. (author), Friesen, Mark (author)Silicon/silicon-germanium heterostructures have many important advantages for hosting spin qubits. However, controlling the valley splitting (the energy splitting between the two low-lying conduction-band valleys) remains a critical challenge for ensuring qubit reliability. Broad distributions of valley splittings are commonplace, even among...journal article 2023

(author), Yacoby, A. (author)Radio-frequency (rf) reflectometry offers a fast and sensitive method for charge sensing and spin readout in gated quantum dots. We focus in this work on the implementation of rf readout in accumulation-mode gate-defined quantum dots, where the large parasitic capacitance poses a challenge. We describe and test two methods for mitigating the...journal article 2021

Bendor, R. (author), Eriksson, Elina (author), Pargman, Daniel (author)While the past is present in all futuring activities it tends to remain implicit and has not received adequate attention by futures scholars and practitioners. In response, this conceptual paper offers a novel framework with which the past can be brought into futures studies in a structured and comprehensive way. We begin by providing a brief...journal article 2021

Kornich, V. (author), Vavilov, Maxim G. (author), Friesen, Mark (author), Eriksson, M. A. (author), Coppersmith, S. N. (author)We study how the shape of a periodic magnetic field affects the presence of Majorana bound states (MBS) in a nanowire-superconductor system. Motivated by the field configurations that can be produced by an array of nanomagnets, we consider spiral fields with an elliptic cross section and fields with two sinusoidal components. We show that MBS...journal article 2020

Boter, J.M. (author), Xue, X. (author), Krähenmann, T.S. (author), Watson, T.F. (author), Premakumar, Vickram N. (author), Ward, Daniel R. (author), Savage, Donald E. (author), Eriksson, Mark A. (author), Vandersypen, L.M.K. (author)We study spatial noise correlations in a Si/SiGe two-qubit device with integrated micromagnets. Our method relies on the concept of decoherence-free subspaces, whereby we measure the coherence time for two different Bell states, designed to be sensitive only to either correlated or anticorrelated noise, respectively. From these measurements...journal article 2020

(author)The integration of 3D city models with Building Information Models (BIM), coined as GeoBIM, facilitates improved data support to several applications, e.g., 3D map updates, building permits issuing, detailed city analysis, infrastructure design, context-based building design, to name a few. To solve the integration, several issues need to be...journal article 2020

(author), Vandersypen, L.M.K. (author)Quantum error correction is of crucial importance for fault-tolerant quantum computers. As an essential step toward the implementation of quantum error-correcting codes, quantum nondemolition measurements are needed to efficiently detect the state of a logical qubit without destroying it. Here we implement quantum nondemolition measurements...journal article 2020

[“A model for types and levels of human interaction with automation,” IEEE Trans. Syst. Man, Cybern. A, Syst. Humans, vol. 30, no. 3, pp. 286–297, May 2000]. We hypothesized that drivers would...journal article 2019

(author), Wehner, S.D.C. (author), Vandersypen, L.M.K. (author)We report the first complete characterization of single-qubit and two-qubit gate fidelities in silicon-based spin qubits, including cross talk and error correlations between the two qubits. To do so, we use a combination of standard randomized benchmarking and a recently introduced method called character randomized benchmarking, which allows...journal article 2019

(author), Eriksson, M. A. (author)Atomic-scale disorder at the top interface of a Si quantum well is known to suppress valley splitting. Such disorder may be inherited from the underlying substrate and relaxed buffer growth, but can also arise at the top quantum well interface due to the random SiGe alloy. Here, we perform activation energy (transport) measurements in the...journal article 2018

(author), Friesen, Mark (author), Coppersmith, S. N. (author), Eriksson, M.A. (author), Vandersypen, L.M.K. (author)Now that it is possible to achieve measurement and control fidelities for individual quantum bits (qubits) above the threshold for fault tolerance, attention is moving towards the difficult task of scaling up the number of physical qubits to the large numbers that are needed for fault-tolerant quantum computing. In this context, quantum-dot...journal article 2018

Eriksson, A. (author), de Winter, J.C.F. (author), Stanton, Neville A. (author)Driving simulators have been used since the beginning of the 1930s to assist researchers in assessing driver behaviour without putting the driver in harm’s way. The current manuscript describes the implementation of a toolbox for automated driving research on the widely used STISIM platform. The toolbox presented in this manuscript allows...journal article 2018
