Error-corrected Hadamard gate simulated at the circuit level
György P. Gehér, Campbell McLauchlan, Earl T. Campbell +2
We simulate the logical Hadamard gate in the surface code under a circuit-level noise model, compiling it to a physical circuit on square-grid connectivity hardware. Our paper is t…
GPAW: An open Python package for electronic-structure calculations
Jens Jørgen Mortensen, Ask Hjorth Larsen, Mikael Kuisma +44
We review the GPAW open-source Python package for electronic structure calculations. GPAW is based on the projector-augmented wave method and can solve the self-consistent density…
A real-time, scalable, fast and highly resource efficient decoder for a quantum computer
Ben Barber, Kenton M. Barnes, Tomasz Bialas +10
To unleash the potential of quantum computers, noise effects on qubits' performance must be carefully managed. The decoders responsible for diagnosing noise-induced computational e…
Tangling schedules eases hardware connectivity requirements for quantum error correction
Gyorgy P. Geher, Ophelia Crawford, Earl T. Campbell
Quantum computers have the potential to change the way we solve computational problems. Due to the noisy nature of qubits, the need arises to correct physical errors occurring duri…
The Electronic Structure of the Hydrogen Molecule: A Tutorial Exercise in Classical and Quantum Computation
Vincent Graves, Christoph Sünderhauf, Nick S. Blunt +2
In this educational paper, we will discuss calculations on the hydrogen molecule both on classical and quantum computers. In the former case, we will discuss the calculation of mol…
Neural network decoder for near-term surface-code experiments
Boris M. Varbanov, Marc Serra-Peralta, David Byfield +1
Neural-network decoders can achieve a lower logical error rate compared to conventional decoders, like minimum-weight perfect matching, when decoding the surface code. Furthermore,…
