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…
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,…
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…
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…
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…
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…
