Self-selective growth of GaAs1-xBix on GaAs zinc blende/wurtzite nanowire heterostructures
Rohit Yadav, Sebastian Lehmann, Vidar Flodgren +5
Site-selective nanostructure growth and material incorporation at the atomic scale offer a promising pathway for engineering quantum materials and nanodevices. Here, GaAs nanowires…
Cathodoluminescence Analysis of Defects and Grain Boundaries in Zn3P2 Thin Films Grown on Graphene by MOVPE and MBE
Thomas Hagger, Mohammadreza Hassanzadeh, Aidas Urbonavicius +12
Zn3P2 is a promising earth-abundant absorber for thin-film photovoltaics, yet its development is hindered by the lack of lattice-matched substrates, its incompatible thermal expans…
Information Thermodynamics in a Quantum Dot Szilard Engine - Experimentally Investigating Fluctuation Theorems and Thermodynamic Uncertainty Relations
David Barker, Sebastian Lehmann, Kimberly A. Dick +3
In Szilard's engine, measurement and feedback allows to extract work from an equilibrium environment, a process otherwise forbidden by the laws of thermodynamics. Recent theoretica…
Unconventional cross sections in zinc phosphide nanowires grown using exclusively earth-abundant components
Simon Escobar Steinvall, Hampus Thulin, Nico Kawashima +8
To enable lightweight and flexible solar cell applications it is imperative to develop direct bandgap absorber materials. Moreover, to enhance the potential sustainability impact o…
Near-Unity Charge Readout in a Nonlinear Resonator without Matching
Harald Havir, Andrea Cicovic, Pierre Glidic +4
Dissipative sensors typically use linear resonators with impedance matching to achieve maximal signal and fast operation. The impedance matching, however, sets an upper limit to th…
Interfaces in epitaxially grown Zn3P2 nanowires and their composition dependent optoelectronic properties for photovoltaic applications
Simon Escobar Steinvall, Francesco Salutari, Jonas Johansson +7
Epitaxially grown nanowires have shown promise for photovoltaic applications due to their nanophotonic properties. Moreover, the mechanical properties of nanowires can reduce cryst…
Coherence of an Electronic Two-Level System under Continuous Charge Sensing by a Quantum Dot Detector
Subhomoy Haldar, Morten Munk, Harald Havir +7
We investigate experimentally the quantum coherence of an electronic two-level system in a double quantum dot under continuous charge detection. The charge-state of the two-level s…
High-efficiency microwave photodetection by cavity coupled double dots with single cavity-photon sensitivity
Subhomoy Haldar, Harald Havir, Waqar Khan +6
We present a superconducting cavity-coupled double quantum dot (DQD) photodiode that achieves a maximum photon-to-electron conversion efficiency of 25% in the microwave domain. Wit…
A coherence sweet spot with enhanced dipolar coupling
Jann H. Ungerer, Alessia Pally, Stefano Bosco +9
Qubits require a compromise between operation speed and coherence. Here, we demonstrate a compromise-free singlet-triplet (ST) qubit, where the qubit couples maximally to the drivi…
Continuous microwave photon counting by semiconductor-superconductor hybrids
Subhomoy Haldar, David Barker, Harald Havir +4
The growing interest in quantum information has enabled the manipulation and readout of microwave photon states with high fidelities. The presently available microwave photon count…
