Molecular nanomagnets (MNMs), molecules containing interacting spins, have been a
playground for quantum mechanics. They are characterized by many accessible low-energy …

The storage and processing of quantum information are susceptible to external noise,
resulting in computational errors. A powerful method to suppress these effects is quantum …

The typical time-independent view of quantum error correction (QEC) codes hides significant
freedom in the decomposition into circuits that are executable on hardware. Using the …

Abstract Recently, Hastings & Haah introduced a quantum memory defined on the
honeycomb lattice. Remarkably, this honeycomb code assembles weight-six parity checks …

Qubits in cavity quantum electrodynamic (QED) architectures are often operated in the
dispersive regime, in which the operating frequency of the cavity depends on the energy …

Qubit initialization is a critical task in quantum computation and communication. Extensive
efforts have been made to achieve this with high speed, efficiency and scalability. However …

Fault-tolerant quantum computing relies on the ability to detect and correct errors, which in
quantum error correction codes is typically achieved by projectively measuring multi-qubit …

Quantum algorithms often benefit from the ability to execute multi-qubit (> 2) gates. To date,
such multi-qubit gates are typically decomposed into single-and two-qubit gates, particularly …

Molecular Nanomagnets may enable the implementation of qudit-based quantum error-
correction codes which exploit the many spin levels naturally embedded in a single …

Parity detection is essential in quantum error correction. Error syndromes coded in parity are
detected routinely by sequential CNOT gates. Here, different from the standard CNOT-gate …
