Practical challenges in simulating quantum systems on classical computers have been
widely recognized in the quantum physics and quantum chemistry communities over the …

Optimization, sampling and machine learning are topics of broad interest that have inspired
significant developments and new approaches in quantum computing. One such approach …

Performing large calculations with a quantum computer will likely require a fault-tolerant
architecture based on quantum error-correcting codes. The challenge is to design practical …

Neutral-atom arrays have recently emerged as a promising platform for quantum information
processing. One important remaining roadblock for the large-scale application of these …

In this work we introduce two code families, which we call the heavy-hexagon code and the
heavy-square code. Both code families are implemented by assigning physical data and …

The manipulation of topologically ordered phases of matter to encode and process quantum
information forms the cornerstone of many approaches to fault-tolerant quantum computing …

We compare two different implementations of fault-tolerant entangling gates on logical
qubits. In one instance, a twelve-qubit trapped-ion quantum computer is used to implement a …

Noise rates in quantum computing experiments have dropped dramatically, but reliable
qubits remain precious. Fault-tolerance schemes with minimal qubit overhead are therefore …

Lattice-surgery protocols allow for the efficient implementation of universal gate sets with two-
dimensional topological codes where qubits are constrained to interact with one another …

Logical gates constitute the building blocks of fault-tolerant quantum computation. While
quantum error-corrected memories have been extensively studied in the literature, explicit …
