Systematic design of broadband parametric amplifiers, circulators, and frequency converters, is enabled by harnessing network-synthesis concepts and methods from microwave engineering.

Using pseudogenerators to dynamically induce an effective model with an enriched local symmetry, disorder-free localization is enhanced in an experimentally feasible setup.

A framework for the characterization of the influence of memory effects in the sequence of gate operation allows for the circumventing of those effects.

The spin relaxation time T1 in graphene quantum dots is shown to be on the order of tens of milliseconds, demonstrating the great potential of spin qubits in this novel material.

A computationally efficient classical algorithm is developed to minimize the resources needed for implementing a fault-tolerant surface code architecture.

A star-shaped, robust and scalable optical fiber network for simultaneous time-bin QKD is experimentally demonstrated with four participants including a field test and more than 100 km of fiber between users as well as full clock recovery.

Analysis shows that controlling Majorana transmon qubit via a gate-based parametric modulation can lead to fidelities close to 99.99%, qubit coherence in the millisecond timescale, and remarkable noise resilience.

An alternative method to confine the state of an oscillator to a cat qubit manifold is developed, leading to fast and bias-preserving gates with drastically improved performance.

Temporal correlations can be used to detect and quantify non-breaking channels without the need for bipartite entangled states, and to characterize resources in quantum information.

A method to create a continuum of dynamical sweet spots is experimentally demonstrated, greatly expanding the range of superconducting qubit frequencies achievable while protecting against noise.

APS Editor in Chief, Michael Thoennessen, discusses a new opportunity for communicating authors to include their pronouns together with their contact email in order to promote a more respectful, inclusive, and equitable environment.

I am delighted to introduce the first issue of PRX Quantum, the first open access, highly-selective topical journal in the Physical Review portfolio, published by the American Physical Society (APS).

It is our pleasure to introduce PRX Quantum to the quantum information science and technology research community.
