Breaking Memory Bottlenecks in Quantum Control Systems for More Precise Experiments and Higher Throughput Computing
Yicheng Guang, Neel Vora, Yilun Xu +2
As quantum computing continues to demonstrate promise and attract growing attention, there is an increasing need for more precise experiments to advance the development of quantum…
A Scalable Open-Source QEC System with Sub-Microsecond Decoding-Feedback Latency
Junyi Liu, Yi Lee, Yilun Xu +2
Quantum error correction (QEC) is essential for realizing large-scale, fault-tolerant quantum computation, yet its practical implementation remains a major engineering challenge. I…
Time-series based quantum state discrimination
Samuel Jung, Neel Vora, Akel Hashim +2
Accurate quantum state readout is crucial for error correction and algorithms, but measurement errors are detrimental. Readout fidelity is typically limited by a poor signal-to-noi…
Platform Architecture for Tight Coupling of High-Performance Computing with Quantum Processors
Shane A. Caldwell, Moein Khazraee, Elena Agostini +27
We propose an architecture, called NVQLink, for connecting high-performance computing (HPC) resources to the control system of a quantum processing unit (QPU) to accelerate workloa…
Multi-FPGA Synchronization and Data Communication for Quantum Control and Measurement
Yilun Xu, Abhi D. Rajagopala, Neelay Fruitwala +1
In the last decade, quantum computing has grown from novel physics experiments with a few qubits to commercial systems with hundreds of qubits. As quantum computers continue to gro…
First-principle crosstalk dynamics and Hamiltonian learning via Rabi experiments
Jan Balewski, Adam Winick, Yilun Xu +5
Coherent errors constitute a significant barrier to successful large-scale quantum computation. One such error mechanism is crosstalk, which violates spatial locality or the indepe…
