A matching decomposition algorithm for simulating quantum walk Hamiltonians
Mostafa Atallah, Alvin Gonzales, Daniel Dilley +3
In this work, we present a new algorithm for generating quantum circuits that efficiently implement continuous time quantum walks on arbitrary simple sparse graphs. The algorithm,…
Gate Teleportation vs Circuit Cutting in Distributed Quantum Computing
Shobhit Gupta, Nikolay Sheshko, Daniel J. Dilley +3
Distributing circuits across quantum processor modules will enable the execution of circuits larger than the qubit count limitations of monolithic processors. While distributed qua…
QuantEM: The quantum error management compiler
Ji Liu, Quinn Langfitt, Mingyoung Jessica Jeng +7
As quantum computing advances toward fault-tolerant architectures, quantum error detection (QED) has emerged as a practical and scalable intermediate strategy in the transition fro…
Quantum Distribution Error Mitigation via the Circulant Structure of Pauli Noise
Alvin Gonzales
This work introduces distribution error mitigation (DEM), which mitigates the error in the output distribution of a quantum circuit. We provide a rigorous theoretical foundation. I…
Quantum Advantage in Distributed Sensing with Noisy Quantum Networks
Allen Zang, Alexander Kolar, Alvin Gonzales +5
We show that quantum advantage in distributed sensing can be achieved with noisy quantum networks which only distribute noisy entangled states. We derive a closed-form expression o…
QuCLEAR: Clifford Extraction and Absorption for Quantum Circuit Optimization
Ji Liu, Alvin Gonzales, Benchen Huang +2
Quantum computing carries significant potential for addressing practical problems. However, currently available quantum devices suffer from noisy quantum gates, which degrade the f…
Dynamic Resource Allocation with Quantum Error Detection
Quinn Langfitt, Alvin Gonzales, Joshua Gao +4
Quantum processing units (QPUs) are highly heterogeneous in terms of physical qubit performance. To add even more complexity, drift in quantum noise landscapes has been well-docume…
Extrapolating Pauli Checks for Expectation Value Estimation on Noisy Quantum Devices
Quinn Langfitt, Ji Liu, Benchen Huang +4
Pauli Check Sandwiching (PCS) is an error detection scheme that protects quantum circuits by inserting pairs of parity checks and discarding runs that signal errors. However, each…
Efficient Sparse State Preparation via Quantum Walks
Alvin Gonzales, Rebekah Herrman, Colin Campbell +4
Continuous-time quantum walks (CTQWs) on dynamic graphs, referred to as dynamic CTQWs, are a recently introduced universal model of computation that offers a new paradigm in which…
QuTracer: Mitigating Quantum Gate and Measurement Errors by Tracing Subsets of Qubits
Peiyi Li, Ji Liu, Alvin Gonzales +3
Quantum error mitigation plays a crucial role in the current noisy-intermediate-scale-quantum (NISQ) era. As we advance towards achieving a practical quantum advantage in the near…
