LEGO_HQEC: Automating the Analysis, Construction, and Decoding of Holographic Quantum Codes

Junyu Fan, Matthew Steinberg, Alexander Jahn +3

Quantum error correction (QEC) is a crucial prerequisite for future large-scale quantum computation. Finding and analyzing new QEC codes, along with efficient decoding and fault-to…

Biased-Noise Thresholds of Zero-Rate Holographic Codes with Tensor-Network Decoding

Junyu Fan, Matthew Steinberg, Alexander Jahn +2

A crucial insight for practical quantum error correction is that different types of errors, such as single-qubit Pauli operators, typically occur with different probabilities. Find…

Far from Perfect: Quantum Error Correction with (Hyperinvariant) Evenbly Codes

Matthew Steinberg, Junyu Fan, Robert J. Harris +3

We introduce a new class of qubit codes that we call Evenbly codes, building on a previous proposal of hyperinvariant tensor networks. Its tensor network description consists of lo…

Universal fault-tolerant logic with heterogeneous holographic codes

Matthew Steinberg, Junyu Fan, Jens Eisert +3

The study of holographic bulk-boundary dualities has led to the construction of novel quantum error correcting codes. Although these codes have shed new light on conceptual aspects…

Near-Term Spin-Qubit Architecture Design via Multipartite Maximally-Entangled States

Nikiforos Paraskevopoulos, Matthew Steinberg, Brennan Undseth +4

The design and benchmarking of quantum computer architectures traditionally rely on practical hardware restrictions, such as gate fidelities, control, and cooling. At the theoretic…
