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…
Efficient Generation of Multi-partite Entanglement between Non-local Superconducting Qubits using Classical Feedback
Akel Hashim, Ming Yuan, Pranav Gokhale +8
Quantum entanglement is one of the primary features which distinguishes quantum computers from classical computers. In gate-based quantum computing, the creation of entangled state…
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…
Hardware-Assisted Parameterized Circuit Execution
Abhi D. Rajagopala, Akel Hashim, Neelay Fruitwala +6
Standard compilers for quantum circuits decompose arbitrary single-qubit gates into a sequence of physical X(pi/2) pulses and virtual-Z phase gates. Consequently, many circuit clas…
