Efficient experimental design of high-fidelity three-qubit quantum gates via genetic programming
Amit Devra, Prithviraj Prabhu, Harpreet Singh +2
We have designed efficient quantum circuits for the three-qubit Toffoli (controlled-controlled NOT) and the Fredkin (controlled-SWAP) gate, optimized via genetic programming method…
Dynamical Decoupling using Universal Optimal Tracking
Amit Devra, Emanuel Malvetti, Niklas J. Glaser +7
Dynamical decoupling (DD) is a widely used and resource-efficient technique for error suppression, but conventional DD relies on periodically repeating a short pulse block to refoc…
Superconducting Qubit Gates Robust to Parameter Fluctuations
Emily Wright, Leo Van Damme, Niklas J. Glaser +14
State-of-the-art single-qubit gates on superconducting transmon qubits can achieve the fidelities required for error-corrected computations. However, parameter fluctuations due to…
Wigner State and Process Tomography on Near-Term Quantum Devices
Amit Devra, Niklas J. Glaser, Dennis Huber +1
We present an experimental scanning-based tomography approach for near-term quantum devices. The underlying method has previously been introduced in an ensemble-based NMR setting.…
Theory and Experimental Demonstration of Wigner Tomography of Unknown Unitary Quantum Gates
Amit Devra, Léo Van Damme, Frederik vom Ende +2
We investigate the tomography of unknown unitary quantum processes within the framework of a finite-dimensional Wigner-type representation. This representation provides a rich visu…
Tackling the Challenges of Adding Pulse-level Support to a Heterogeneous HPCQC Software Stack: MQSS Pulse
Jorge Echavarria, Muhammad Nufail Farooqi, Amit Devra +22
We study the problem of adding native pulse-level control to heterogeneous High Performance Computing-Quantum Computing (HPCQC) software stacks, using the Munich Quantum Software S…
