- Abstract: We introduce Weyl Josephson circuits: small Josephson junction circuits that
simulate Weyl band structures. We first formulate a general approach to design
circuits that are analogous to Bloch Hamiltonians of a desired dimensionality
and symmetry class. We then construct and analyze a six-junction device that
produces a 3D Weyl Hamiltonian with broken inversion symmetry and in which
topological phase transitions can be triggered \emph{in situ}. We argue that
currently available superconducting circuit technology allows experiments that
probe topological properties inaccessible in condensed matter systems.

In condensed matter systems, non-trivial topology may manifest itself as singular features in the energy spectrum or the quantization of observable quantities.
We show that a superconducting circuit with three Josephson tunnel junctions in parallel can possess energy degeneracies indicative of $textrmemphintrinsic$ non-trivial topology.

For planar circuits, known circuit dualities are a natural canonical transformation on the classical phase space.
We discuss the extent to which such circuit dualities generalize to non-planar circuits.

and connections to phase-space and Keldysh field theory formulations [77.34726150561087]
We reformulate the technique of third quantization in a way that explicitly connects all three methods.
We first show that our formulation reveals a fundamental dissipative symmetry present in all quadratic bosonic or fermionic Lindbladians.
For bosons, we then show that the Wigner function and the characteristic function can be thought of as ''wavefunctions'' of the density matrix.

Unitary evolution under a time dependent Hamiltonian is a key component of simulation on quantum hardware.
We present an algorithm that compresses the Trotter steps into a single block of quantum gates.
This results in a fixed depth time evolution for certain classes of Hamiltonians.

We present a circuit design composed of a non-reciprocal device and Josephson junctions whose ground space is doubly degenerate and the ground states are approximate codewords of the Gottesman-Kitaev-Preskill (GKP) code.
We find that the circuit is naturally protected against the common noise channels in superconducting circuits, such as charge and flux noise, implying that it can be used for passive quantum error correction.
