Nanostructure modelling with early fault tolerant quantum computers
Zhu Sun, Christian Binder, Balint Koczor +1
Semiconductor nanostructures are central to many developing technologies. Notably, double quantum dots are especially important for semiconductor spin-qubit architectures, quantum…
A Folded Surface Code Architecture for 2D Quantum Hardware
Zhu Sun, Zhenyu Cai
Qubit shuttling has become an indispensable ingredient for scaling leading quantum computing platforms, including semiconductor spin, neutral-atom, and trapped-ion qubits, enabling…
Space and Time Cost of Continuous Rotations in Surface Codes
Zhu Sun, Balint Koczor
While Clifford operations are relatively easy to implement in fault-tolerant quantum computers,continuous rotation gates remain a significant bottleneck in typical quantum algorith…
Low Depth Phase Oracle Using a Parallel Piecewise Circuit
Zhu Sun, Gregory Boyd, Zhenyu Cai +7
We explore the important task of applying a phase to a computational basis state . The closely related task of rotating a target qubit by an angle…
