Comparing Schemes for Creating Qudit Graph States from 16- & 128-dimensional Hilbert Space using Donors in Silicon
Gözde Üstün, Simon J. Devitt
In this work, we compare two schemes for generating arbitrary qudit graph states using spin qudits in silicon. The first scheme proposes the creation of qudit linear graph states f…
Blind-spots of Randomized Benchmarking Under Temporal Correlations
Varun Srivastava, Abhinash Kumar Roy, Soumik Mahanti +3
Randomized benchmarking (RB) is a widely adopted protocol for estimating the average gate fidelity in quantum hardware. However, its standard formulation relies on the assumption o…
Expanding the Class of Free Fermions via Twin-Collapse Methods
Jannis Ruh, Samuel J. Elman
We present a novel graph-theoretic approach to simplifying generic many-body Hamiltonians. Our primary result introduces a recursive twin-collapse algorithm, leveraging the identif…
Approximation does not help in quantum unitary time-reversal
Kean Chen, Nengkun Yu, Zhicheng Zhang
Access to the time-reverse of an unknown quantum unitary process is widely assumed in quantum learning, metrology, and many-body physics. The fundamental task of unita…
Quantifying Spin Defect Density in hBN via Raman and Photoluminescence Analysis
Atanu Patra, Paul Konrad, Andreas Sperlich +6
Negatively charged boron vacancies () in hexagonal boron nitride (hBN) are emerging as promising solid-state spin qubits due to their optical accessibility, structu…
Noise-reduction of multimode Gaussian Boson Sampling circuits via Unitary Averaging
S. Nibedita Swain, Ryan J. Marshman, Alexander S. Solntsev +1
We improve Gaussian Boson Sampling (GBS) circuits by integrating the unitary averaging (UA) protocol, previously demonstrated to protect unknown Gaussian states from phase errors […
Fusion for High-Dimensional Linear Optical Quantum Computing with Improved Success Probability
Gözde Üstün, Eleanor G. Rieffel, Simon J. Devitt +1
Type-II fusion is a probabilistic entangling measurement that is essential to measurement-based linear optical quantum computing and can be used for quantum teleportation more broa…
Short-time quantum Fourier transform processing
Sreeraj Rajindran Nair, Benjamin Southwell, Christopher Ferrie
Algorithms for processing data in short-time batches are critical for both online and offline processing of streamed and large data respectively due to the quadratic relation betwe…
Machine Learning for Estimation and Control of Quantum Systems
Hailan Ma, Bo Qi, Ian R. Petersen +3
The development of quantum technologies relies on creating and manipulating quantum systems of increasing complexity, with key applications in computation, simulation, and sensing.…
Intermediate Excited State Relaxation Dynamics of Boron Vacancy Spin Defects in Hexagonal Boron Nitride
Paul Konrad, Mehran Kianinia, Lesley Spencer +5
Optically addressable spin defects in hexagonal boron nitride offer promising potential for 2D quantum sensing, though excited-state dynamics remain poorly understood. In particula…
Learning-Based Design of LQG Controllers in Quantum Coherent Feedback
Chunxiang Song, Yanan Liu, Guofeng Zhang +2
In this paper, we propose a differential evolution (DE) algorithm specifically tailored for the design of Linear-Quadratic-Gaussian (LQG) controllers in quantum systems. Building u…
The Complexity of Local Stoquastic Hamiltonians on 2D Lattices
Gabriel Waite, Michael J. Bremner
We show the 2-Local Stoquastic Hamiltonian problem on a 2D square qubit lattice is StoqMA-complete. We achieve this by extending the spatially sparse circuit construction of Olivei…
Near-deterministic photon entanglement from a spin qudit in silicon using third quantisation
Gözde Üstün, Samuel Elman, Jarryd J. Pla +3
Unlike other quantum hardware, photonic quantum architectures can produce millions of qubits from a single device. However, controlling photonic qubits remains challenging, even at…
Quantum Feature-Empowered Deep Classification for Fast Mangrove Mapping
Chia-Hsiang Lin, Po-Wei Tang, Alfredo R. Huete
A mangrove mapping (MM) algorithm is an essential classification tool for environmental monitoring. The recent literature shows that compared with other index-based MM methods that…
