Limitations of Clustering Using Quantum Persistent Homology
Niels Neumann, Sterre den Breeijen
Different algorithms can be used for clustering purposes with data sets. On of these algorithms, uses topological features extracted from the data set to base the clusters on. The…
A gate-tunable, field-compatible fluxonium
Marta Pita-Vidal, Arno Bargerbos, Chung-Kai Yang +7
Circuit quantum electrodynamics, where photons are coherently coupled to artificial atoms built with superconducting circuits, has enabled the investigation and control of macrosco…
Entanglement between a diamond spin qubit and a photonic time-bin qubit at telecom wavelength
Anna Tchebotareva, Sophie L. N. Hermans, Peter C. Humphreys +8
We report on the realization and verification of quantum entanglement between an NV electron spin qubit and a telecom-band photonic qubit. First we generate entanglement between th…
Protecting quantum entanglement from leakage and qubit errors via repetitive parity measurements
C. C. Bultink, T. E. O'Brien, R. Vollmer +9
Protecting quantum information from errors is essential for large-scale quantum computation. Quantum error correction (QEC) encodes information in entangled states of many qubits,…
A fast, low-leakage, high-fidelity two-qubit gate for a programmable superconducting quantum computer
M. A. Rol, F. Battistel, F. K. Malinowski +8
A common approach to realize conditional-phase (CZ) gates in transmon qubits relies on flux control of the qubit frequency to make computational states interact with non-computatio…
Error Mitigation by Symmetry Verification on a Variational Quantum Eigensolver
R. Sagastizabal, X. Bonet-Monroig, M. Singh +11
Variational quantum eigensolvers offer a small-scale testbed to demonstrate the performance of error mitigation techniques with low experimental overhead. We present successful err…
