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 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}(…
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…
Demonstration of Algorithmic Quantum Speedup for an Abelian Hidden Subgroup Problem
P. Singkanipa, V. Kasatkin, Z. Zhou +2
Simon's problem is to find a hidden period (a bitstring) encoded into an unknown 2-to-1 function. It is one of the earliest problems for which an exponential quantum speedup was pr…
