Discrete states and ballistic interference in quantum wires approaching macroscopic lengths
Henok Weldeyesus, Taras Patlatiuk, Christian P. Scheller +4
Increasing the size of a system showing quantum effects is a difficult task limited by decoherence, a diminishing quantum level spacing, and the effects of disorder spoiling the qu…
Compact self-matched gyrators using edge magnetoplasmons
Aldo Tarascio, Yiqi Zhao, Rafael S. Eggli +5
Edge magnetoplasmons provide a natural platform for chiral electrodynamics, where broken time-reversal symmetry enforces unidirectional propagation. When probed at microwave freque…
A direct dispersive signature of Pauli spin blockade
Simon Svab, Rafael S. Eggli, Taras Patlatiuk +7
Pauli Spin Blockade (PSB) is a key paradigm in semiconductor nanostructures and gives access to the spin physics. We report the direct observation of PSB with gate-dispersive refle…
Finite-bias Coulomb blockade thermometry
Omid Sharifi Sedeh, Christian P. Scheller, Henok Weldeyesus +4
Coulomb blockade thermometers (CBTs) are versatile and, in principle, primary thermometers operating down to the micro-Kelvin range but bias heating spoils the thermometry and the…
All-electrical operation of a spin qubit coupled to a high-Q resonator
Rafael S. Eggli, Taras Patlatiuk, Eoin G. Kelly +5
Building a practical quantum processor involves integrating millions of physical qubits along with the necessary components for individual qubit manipulation and readout. Arrays of…
Fully autonomous tuning of a spin qubit
Jonas Schuff, Miguel J. Carballido, Madeleine Kotzagiannidis +14
Spanning over two decades, the study of qubits in semiconductors for quantum computing has yielded significant breakthroughs. However, the development of large-scale semiconductor…
Compromise-Free Scaling of Qubit Speed and Coherence
Miguel J. Carballido, Simon Svab, Rafael S. Eggli +12
Across leading qubit platforms, a common trade-off persists: increasing coherence comes at the cost of operational speed, reflecting the notion that protecting a qubit from its noi…
Cryogenic hyperabrupt strontium titanate varactors for sensitive reflectometry of quantum dots
Rafael S. Eggli, Simon Svab, Taras Patlatiuk +8
Radio frequency reflectometry techniques enable high bandwidth readout of semiconductor quantum dots. Careful impedance matching of the resonant circuit is required to achieve high…
Charge-sensing of a Ge/Si core/shell nanowire double quantum dot using a high-impedance superconducting resonator
J. H. Ungerer, P. Chevalier Kwon, T. Patlatiuk +6
Spin qubits in germanium are a promising contender for scalable quantum computers. Reading out of the spin and charge configuration of quantum dots formed in Ge/Si core/shell nanow…
Edge State Wave Functions from Momentum-Conserving Tunneling Spectroscopy
T. Patlatiuk, C. P. Scheller, D. Hill +7
We perform momentum-conserving tunneling spectroscopy using a GaAs cleaved-edge overgrowth quantum wire to investigate adjacent quantum Hall edge states. We use the lowest five wir…
Template-assisted scalable nanowire networks
Martin Friedl, Kris Cerveny, Pirmin Weigele +15
Topological qubits based on Majorana fermions have the potential to revolutionize the emerging field of quantum computing by making information processing significantly more robust…
Evolution of the quantum Hall bulk spectrum into chiral edge states
Taras Patlatiuk, Christian P. Scheller, Daniel Hill +6
One of the most intriguing and fundamental properties of topological materials is the correspondence between the conducting edge states and the gapped bulk spectrum. So far, it has…
