Coupled charge and energy transfer dynamics in light harvesting complexes from a hybrid hierarchical equations of motion approach

Kavli Affiliate: David T. Limmer | First 5 Authors: Thomas P. Fay, David T. Limmer, , , | Summary: We describe a method for simulating exciton dynamics in protein-pigment complexes, including effects from charge transfer as well as fluorescence. The method combines the hierarchical equations of motion, which are used to describe quantum dynamics of […]

Benchmarking verified logic operations for fault tolerance

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Akel Hashim, Stefan Seritan, Timothy Proctor, Kenneth Rudinger, Noah Goss | Summary: The promise of quantum computing depends upon the eventual achievement of fault-tolerant quantum error correction, which requires that the total rate of errors falls below some threshold. However, most contemporary methods for benchmarking noisy quantum […]

Benchmarking quantum logic operations for achieving fault tolerance

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Akel Hashim, Stefan Seritan, Timothy Proctor, Kenneth Rudinger, Noah Goss | Summary: Contemporary methods for benchmarking noisy quantum processors typically measure average error rates or process infidelities. However, thresholds for fault-tolerant quantum error correction are given in terms of worst-case error rates — defined via the diamond […]

Demonstrating scalable randomized benchmarking of universal gate sets

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Jordan Hines, Marie Lu, Ravi K. Naik, Akel Hashim, Jean-Loup Ville | Summary: Randomized benchmarking (RB) protocols are the most widely used methods for assessing the performance of quantum gates. However, the existing RB methods either do not scale to many qubits or cannot benchmark a universal […]
