Mitigating Dynamic Crosstalk with Optimal Control
Matthias G. Krauss, Luise C. Butzke, Christiane P. Koch
The prevalence of quantum crosstalk is an important barrier to scaling frequency-addressable qubit architectures, with dynamic crosstalk being particularly difficult to detect and…
Obstacles to Continuous Quantum Error Correction via Parity Measurements
Anton Halaski, Christiane P. Koch
Time-continuous quantum error correction, necessary to protect quantum information under time-dependent Hamiltonians, relies on weak continuous syndrome measurements. Implementing…
Motional entanglement in low-energy collisions near shape resonances
Yimeng Wang, Christiane P. Koch
Einstein, Podolsky, and Rosen discussed their paradox in terms of measuring the positions or momenta of two particles. These degrees of freedom can become entangled upon scattering…
Introduction to quantum control: From basic concepts to applications in quantum technologies
Christiane P. Koch
Quantum control refers to our ability to manipulate quantum systems. This tutorial-style chapter focuses on the use of classical electromagnetic fields to steer the system dynamics…
Achieving fast and robust perfect entangling gates via reinforcement learning
Leander Grech, Matthias G. Krauss, Mirko Consiglio +4
Noisy intermediate-scale quantum computers hold the promise of tackling complex and otherwise intractable computational challenges through the massive parallelism offered by qubits…
Scalable modular architecture for universal quantum computation
Fernando Gago-Encinas, Christiane P. Koch
Universal quantum computing requires the ability to perform every unitary operation, i.e., evolution operator controllability. In view of developing resource-efficient quantum proc…
