Classical Simulation of Quantum Noise
Daniel Crow, Robert Joynt
Dephasing decoherence induced by interaction of one qubit with a quantum bath can be simulated classically by random unitary evolution without the need for a bath and this random u…
Measurement-free implementations of small-scale surface codes for quantum dot qubits
H. Ekmel Ercan, Joydip Ghosh, Daniel Crow +4
The performance of quantum error correction schemes depends sensitively on the physical realizations of the qubits and the implementations of various operations. For example, in qu…
2-Designs and Redundant Syndrome Extraction for Quantum Error Correction
Vickram N. Premakumar, Hele Sha, Daniel Crow +2
Imperfect measurement can degrade a quantum error correction scheme. A solution that restores fault tolerance is to add redundancy to the process of syndrome extraction. In this wo…
Fault-tolerant quantum computation with a neutral atom processor
Ben W. Reichardt, Adam Paetznick, David Aasen +69
Quantum computing experiments are transitioning from running on physical qubits to using encoded, logical qubits. Fault-tolerant computation can identify and correct errors, and ha…
Quantum Subspace Correction for Constraints
Kelly Ann Pawlak, Jeffrey M. Epstein, Daniel Crow +4
We demonstrate that it is possible to construct operators that stabilize the constraint-satisfying subspaces of computational problems in their Ising representations. We provide an…
Improved error thresholds for measurement-free error correction
Daniel Crow, Robert Joynt, Mark Saffman
Motivated by limitations and capabilities of neutral atom qubits, we examine whether measurement-free error correction can produce practical error thresholds. We show that this can…
