No need to calibrate: characterization and compilation for high-fidelity circuit execution using imperfect gates
Ashish Kakkar, Samuel Marsh, Yulun Wang +5
We propose and validate on real quantum computing hardware a new method for extended two-qubit gate set design, replacing iterative, fine calibration with fast characterization of…
A quantum annealing approach to the minimum distance problem of quantum codes
Refat Ismail, Ashish Kakkar, Anatoly Dymarsky
Quantum error-correcting codes (QECCs) is at the heart of fault-tolerant quantum computing. As the size of quantum platforms is expected to grow, one of the open questions is to de…
Spectrum of quantum KdV hierarchy in the semiclassical limit
Anatoly Dymarsky, Ashish Kakkar, Kirill Pavlenko +1
We employ semiclassical quantization to calculate spectrum of quantum KdV charges in the limit of large central charge . Classically, KdV charges generate completely…
Narain CFTs and Quantum Codes at Higher Genus
Johan Henriksson, Ashish Kakkar, Brian McPeak
Code CFTs are 2d conformal field theories defined by error-correcting codes. Recently, Dymarsky and Shapere generalized the construction of code CFTs to include quantum error-corre…
Characterizing Error Mitigation by Symmetry Verification in QAOA
Ashish Kakkar, Jeffrey Larson, Alexey Galda +1
Hardware errors are a major obstacle to demonstrating quantum advantage with the quantum approximate optimization algorithm (QAOA). Recently, symmetry verification has been propose…
Classical Codes and Chiral CFTs at Higher Genus
Johan Henriksson, Ashish Kakkar, Brian McPeak
Higher genus modular invariance of two-dimensional conformal field theories (CFTs) is a largely unexplored area. In this paper, we derive explicit expressions for the higher genus…
