Heterogeneous architectures enable a 138x reduction in physical qubit requirements for fault-tolerant quantum computing under detailed accounting

Pranav S. Mundada, Aleksei Khindanov, Yulun Wang +5

Quantum computer hardware is predicted to scale over hundreds of thousands of qubits coming online in the next decade. Despite significant theoretical and experimental QEC progress…

No need to calibrate: characterization and compilation for high-fidelity circuit execution using imperfect gates

Ashish Kakkar, Samuel Marsh, Yulun Wang +5

We propose and validate on real quantum computing hardware a new method for extended two-qubit gate set design, replacing iterative, fine calibration with fast characterization of…

Automated discovery of heralded ballistic graph state generators for fusion-based photonic quantum computation

Gavin S. Hartnett, Dave Kielpinski, Smarak Maity +3

Designing photonic circuits that prepare graph states with high fidelity and success probability is a central challenge in linear optical quantum computing. Existing approaches rel…

Achieving computational gains with quantum error-correction primitives: Generation of long-range entanglement enhanced by error detection

Haoran Liao, Gavin S. Hartnett, Ashish Kakkar +5

The resource overhead required to achieve net computational benefits from quantum error correction (QEC) limits its utility while current systems remain constrained in size, despit…

Resource-efficient context-aware dynamical decoupling embedding for arbitrary large-scale quantum algorithms

Paul Coote, Roman Dimov, Smarak Maity +3

We introduce and implement GraphDD: an efficient method for real-time, circuit-specific, optimal embedding of dynamical decoupling (DD) into executable quantum algorithms. We demon…
