Engineering Hybrid Epitaxial InAsSb/Al Nanowire Materials for Stronger Topological Protection
Joachim E. Sestoft, Thomas Kanne, Aske Nørskov Gejl +11
The combination of strong spin-orbit coupling, large -factors, and the coupling to a superconductor can be used to create a topologically protected state in a semiconductor nano…
Chip-to-chip entanglement of transmon qubits using engineered measurement fields
C. Dickel, J. J. Wesdorp, N. K. Langford +6
While the on-chip processing power in circuit QED devices is growing rapidly, an open challenge is to establish high-fidelity quantum links between qubits on different chips. Here,…
Adaptive weight estimator for quantum error correction
S. T. Spitz, B. Tarasinski, C. W. J. Beenakker +1
Quantum error correction of a surface code or repetition code requires the pairwise matching of error events in a space-time graph of qubit measurements, such that the total weight…
Observation of the 4-periodic Josephson effect in indium arsenide nanowires
Dominique Laroche, Daniël Bouman, David J. van Woerkom +9
Quantum computation by non-Abelian Majorana zero modes (MZMs) offers an approach to achieve fault tolerance by encoding quantum information in the non-local charge parity states of…
SimulaQron - A simulator for developing quantum internet software
Axel Dahlberg, Stephanie Wehner
We introduce a simulator for a quantum internet with the specific goal to support software development. A quantum internet consists of local quantum processors, which are interconn…
The Small Stellated Dodecahedron Code and Friends
Jonathan Conrad, Christopher Chamberland, Nikolas P. Breuckmann +1
We explore a distance-3 homological CSS quantum code, namely the small stellated dodecahedron code, for dense storage of quantum information and we compare its performance with the…
Lowering qubit requirements for quantum simulations of fermionic systems
Mark Steudtner, Stephanie Wehner
The mapping of fermionic states onto qubit states, as well as the mapping of fermionic Hamiltonian into quantum gates enables us to simulate electronic systems with a quantum compu…
Majorana-based fermionic quantum computation
T. E. O'Brien, P. Rożek, A. R. Akhmerov
Because Majorana zero modes store quantum information non-locally, they are protected from noise, and have been proposed as a building block for a quantum computer. We show how to…
Demonstration of Entanglement Purification and Swapping Protocol to Design Quantum Repeater in IBM Quantum Computer
Bikash K. Behera, Swarnadeep Seth, Antariksha Das +1
Quantum communication is a secure way to transfer quantum information and to communicate with legitimate parties over distant places in a network. Although communication over a lon…
Entanglement and secret-key-agreement capacities of bipartite quantum interactions and read-only memory devices
Siddhartha Das, Stefan Bäuml, Mark M. Wilde
A bipartite quantum interaction corresponds to the most general quantum interaction that can occur between two quantum systems in the presence of a bath. In this work, we determine…
Evolution of Nanowire Transmons and Their Quantum Coherence in Magnetic Field
F. Luthi, T. Stavenga, O. W. Enzing +8
We present an experimental study of nanowire transmons at zero and applied in-plane magnetic field. With Josephson non-linearities provided by the nanowires, our qubits operate at…
