Demonstration of Exponential Quantum Speedup with Constant-Depth Compiled Circuits for Simon's Problem
Phattharaporn Singkanipa, Victor Kasatkin, Daniel A. Lidar
We demonstrate exponential algorithmic quantum speedup for a restricted-Hamming-weight version of Simon's problem, in which the hidden string is promised to satisfy $\text{HW}(…
Quantum Error Correction and Dynamical Decoupling: Better Together or Apart?
Victor Kasatkin, Mario Morford-Oberst, Arian Vezvaee +1
Quantum error correction/detection (QEC/QED) and dynamical decoupling (DD) are tools for protecting quantum information. A natural goal is to combine them to outperform either appr…
Demonstration of High-Fidelity Entangled Logical Qubits using Transmons
Arian Vezvaee, Vinay Tripathi, Mario Morford-Oberst +3
Quantum error correction (QEC) codes are necessary to fault-tolerantly operate quantum computers. However, every such code is inherently limited by its inability to detect logical…
Detecting Quantum and Classical Phase Transitions via Unsupervised Machine Learning of the Fisher Information Metric
Victor Kasatkin, Evgeny Mozgunov, Nicholas Ezzell +1
The detection of quantum and classical phase transitions in the absence of an order parameter is possible using the Fisher information metric (FIM), also known as fidelity suscepti…
