Simulating the Dynamics of Markovian Quantum Processes by Quantum Collision Models on Quantum Computers
Zeqing Wang, Julian D. Teske, Anshuman Bhardwaj +2
Hamiltonian dynamics have been widely implemented on noisy intermediate-scale quantum devices in recent years. In contrast, experimental demonstrations of Markovian quantum dynamic…
Driving Exchange Interaction in Spin Qubits with Quasi-Zero Pulses
Julian D. Teske, Remy L. Delva, Shobhan Kulshreshtha +6
The implementation of high-fidelity quantum gates for spin qubits requires accurate control of exchange interactions between electrons confined in quantum dots, but pulse distortio…
Data-Driven Qubit Characterization and Optimal Control using Deep Learning
Paul Surrey, Julian D. Teske, Tobias Hangleiter +2
Quantum computing requires the optimization of control pulses to achieve high-fidelity quantum gates. We propose a machine learning-based protocol to address the challenges of eval…
Strategies for enhancing spin-shuttling fidelities in Si/SiGe quantum wells with random-alloy disorder
Merritt P. Losert, Max Oberländer, Julian D. Teske +5
Coherent coupling between distant qubits is needed for any scalable quantum computing scheme. In quantum dot systems, one proposal for long-distance coupling is to coherently trans…
