Benchmarking Gate Fidelities in a Si/SiGe Two-Qubit Device
X. Xue, T. F. Watson, J. Helsen +7
We report the first complete characterization of single-qubit and two-qubit gate fidelities in silicon-based spin qubits, including cross-talk and error correlations between the tw…
Efficient Unitarity Randomized Benchmarking of Few-qubit Clifford Gates
Bas Dirkse, Jonas Helsen, Stephanie Wehner
Unitarity randomized benchmarking (URB) is an experimental procedure for estimating the coherence of implemented quantum gates independently of state preparation and measurement er…
A new class of efficient randomized benchmarking protocols
Jonas Helsen, Xiao Xue, Lieven M. K. Vandersypen +1
Randomized benchmarking is a technique for estimating the average fidelity of a set of quantum gates. For general gatesets, however, it is difficult to draw robust conclusions from…
How to transform graph states using single-qubit operations: computational complexity and algorithms
Axel Dahlberg, Jonas Helsen, Stephanie Wehner
Graph states are ubiquitous in quantum information with diverse applications ranging from quantum network protocols to measurement based quantum computing. Here we consider the que…
