Encoding a qubit in a high-quality superconducting microwave cavity offers the opportunity
to perform the first layer of error correction in a single device but presents a challenge: how …

Approaches to developing large-scale superconducting quantum processors must cope with
the numerous microscopic degrees of freedom that are ubiquitous in solid-state devices …

With its rich dynamics, the quantum harmonic oscillator is an innate platform for
understanding real-world quantum systems and could even excel as the heart of a quantum …

We present a systematic method to design arbitrary energy-phase relations using parallel
arms of two series Josephson tunnel junctions each. Our approach employs Fourier …

Cat qubits, for which logical| 0⟩ and| 1⟩ are coherent states|±α⟩ of a harmonic mode, offer
a promising route towards quantum error correction. Using dissipation to our advantage so …

Dissipationless nonlinearities for three-wave mixing are a key component of many
superconducting quantum devices, such as amplifiers and bosonic qubits. So far, such third …

We introduce a general method based on the operators of the Dyson-Masleev
transformation to map the Hamiltonian of an arbitrary model system into the Hamiltonian of a …

In lumped-element electrical circuit theory, the problem of solving Maxwell's equations in the
presence of media is reduced to two sets of equations, the constitutive equations …

Following a consistent geometrical description previously introduced in Parra-Rodriguez et
al.(2023), we present an exact method for obtaining canonically quantisable Hamiltonian …
