Special Issue Information
Dear Colleagues,
The superconducting circuit QED has emerged as a programmable platform for quantum simulation of many-body physics. In the circuit, arrays of qubits and resonators implement interacting light–matter Hamiltonians with lithographic scalability, in-situ tunability of frequencies, couplings, and dissipation, single-photon control/readout, and compatibility with parametric driving and reservoir engineering. These capabilities make circuit QED uniquely suited to emulate strongly correlated models—ranging from Bose–Hubbard/Jaynes–Cummings/Rabi lattices and spin–boson networks to driven-dissipative criticality, topological bands, localization/glassiness, and gauge-theory analogs—while directly interfacing with quantum-technology building blocks. Beyond faithful emulation, circuit QED supports digital-analog strategies, programmable nonlinearity, and noise/measurement engineering that enable access to nonequilibrium phases and critical dynamics that are hard to capture classically. The platform’s native microwave photonics allows for quantum-limited amplification, nonreciprocal transport, and bosonic encoding/stabilization to be co-designed with the simulator itself, and its hybrid compatibility extends the landscape of simulable Hamiltonians and probes. As devices grow in scale and coherence improves, circuit QED offers a realistic route to benchmarking quantum advantage in many-body dynamics and to translating simulated insights into deployable components for sensing, communications, and fault-tolerant computing. Continued investment in this line of research is therefore essential—not only to deepen our understanding of correlated quantum matter, but also to accelerate the maturation of practical quantum technologies built on controllable light–matter interactions.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
