Maximum-Likelihood Amplitude Estimation for Quantum Monte Carlo Integration on Trapped-Ion Hardware: Convergence, Noise-Floor Saturation, Depth-Dependent Bias
Aditi Lal, Alex Khan, Rut Lineswala +1
Quantum Amplitude Estimation promises to accelerate Monte Carlo integration by replacing the classical sampling law with the Heisenberg-limited $\var…
Measurement and reload costs in direct quantum simulation of nonlinear waves
Ziqing Guo, Viraj Dsouza, Alex Khan +3
Quantum processors encode an N-point field in log_2(N) qubits, which renders nonlinear wave equations an important application for quantum simulation. Nonlinear evolution, however,…
Variational Quantum Linear Solver via Block Encoding for the Poisson Equation
Viraj Dsouza, Ayush Singhal, Alex Khan +2
We present a variational quantum linear solver (VQLS) for the Poisson equation built on an exact block encoding of the discrete Laplacian, and demonstrate its performance on physic…
Quantum Approximate Walk Algorithm
Ziqing Guo, Jan Balewski, Wenshuo Hu +2
The encoding of classical to quantum data mapping through trigonometric functions within arithmetic-based quantum computation algorithms leads to the exploitation of multivariate d…
Vectorized Attention with Learnable Encoding for Quantum Transformer
Ziqing Guo, Ziwen Pan, Alex Khan +1
Vectorized quantum block encoding provides a way to embed classical data into Hilbert space, offering a pathway for quantum models, such as Quantum Transformers (QT), that replace…
Quantum parallel information exchange (QPIE) hybrid network with transfer learning
Ziqing Guo, Alex Khan, Victor S. Sheng +2
Quantum machine learning (QML) has emerged as an innovative framework with the potential to uncover complex patterns by leveraging quantum systems ability to simulate and exploit h…
Eavesdropping on the BB84 Protocol using Phase-Covariant Cloning: Experimental Results
Brian Pigott, Elizabeth Campolongo, Hardik Routray +1
Though the BB84 protocol has provable security over a noiseless quantum channel, the security is not proven over current noisy technology. The level of tolerable error on such syst…
