Control Protocols for Entangling Gates for Group-IV Color-Centers in Diamond
Jurek Frey, Frank K. Wilhelm, Matthias M. Müller
Accurately controlling entangling gates remains a major challenge for quantum technology applications with solid-state spin qubits. Here, we study a group-IV color-center with a st…
Optimal Two-Qubit Gates for Group-IV Color-Centers in Diamond
Jurek Frey, Katharina Senkalla, Philipp J. Vetter +3
Color centers associated with group-IV dopants in diamond with long-lived nuclear spins have emerged as major candidates for distributed quantum computing nodes and quantum repeate…
Gate Optimization via Efficient Two-Qubit Benchmarking for NV Centers in Diamond
Alessandro Marcomini, Philipp J. Vetter, Tommaso Calarco +3
High-fidelity gate implementation requires sophisticated control pulses that steer the quantum system to undergo the desired transformation. Quantum Optimal Control allows to deriv…
High-Fidelity Single-Shot Readout and Selective Nuclear Spin Control for a Spin-1/2 Quantum Register in Diamond
Prithvi Gundlapalli, Philipp J. Vetter, Genko Genov +5
Quantum networks offer a way to overcome the size and complexity limitations of single quantum devices by linking multiple nodes into a scalable architecture. Group-IV color center…
High-Fidelity Electron Spin Gates for Scaling Diamond Quantum Register
Timo Joas, Florian Ferlemann, Roberto Sailer +9
Diamond is a promising platform for quantum information processing as it can host highly coherent qubits that could allow for the construction of large quantum registers. A prerequ…
Circuit Design for a Star-shaped Spin-Qubit Processor via Algebraic Decomposition and Optimal Control
Yaqing X. Wang, Tommaso Calarco, Felix Motzoi +1
As quantum processing units grow in size and precision we enter the stage where quantum algorithms can be tested on actual quantum devices. To implement a given quantum circuit on…
