Growth and optical properties of axial hybrid III-V/Si nanowires
Moïra Hocevar, George Immink, Marcel Verheijen +4
Hybrid silicon nanowires with an integrated light-emitting segment can significantly advance nanoelectronics and nanophotonics. They would combine transport and optical characteris…
Fast spin-orbit qubit in an indium antimonide nanowire
J. W. G. van den Berg, S. Nadj-Perge, V. S. Pribiag +4
Due to the strong spin-orbit interaction in indium antimonide, orbital motion and spin are no longer separated. This enables fast manipulation of qubit states by means of microwave…
A valley-spin qubit in a carbon nanotube
Edward A. Laird, Fei Pei, Leo. P. Kouwenhoven
Although electron spins in III-V semiconductor quantum dots have shown great promise as qubits, a major challenge is the unavoidable hyperfine decoherence in these materials. In gr…
Valley-spin blockade and spin resonance in carbon nanotubes
Fei Pei, Edward A. Laird, Gary A. Steele +1
Manipulation and readout of spin qubits in quantum dots made in III-V materials successfully rely on Pauli blockade that forbids transitions between spin-triplet and spin-singlet s…
Suppression of Zeeman gradients by nuclear polarization in double quantum dots
S. M. Frolov, J. Danon, S. Nadj-Perge +6
We use electric dipole spin resonance to measure dynamic nuclear polarization in InAs nanowire quantum dots. The resonance shifts in frequency when the system transitions between m…
Avalanche amplification of a single exciton in a semiconductor nanowire
Gabriele Bulgarini, Michael E. Reimer, Moïra Hocevar +3
Interfacing single photons and electrons is a crucial ingredient for sharing quantum information between remote solid-state qubits. Semiconductor nanowires offer the unique possibi…
